1 Item #: 145 UPC ( ): SUBMITTER: Guy Wayne Harrison Josam Company RECOMMENDATION: Revise text as follows: Trap Seals. Each fixture trap shall have a water seal of not less than two (2) inches (51 mm) and not more than four (4) inches (102 mm), except where a deeper seal is found necessary by the Authority Having Jurisdiction. Where a trap seal is subject to evaporation, a trap seal primer valve shall be installed. The connection shall be above the water level of the trap weir. Traps shall be set true with respect to their water seals and, where necessary, they shall be protected from freezing. SUBSTANTIATION: By adding in the proposed language to the current provision of the 2006 Code will prevent installing a trap primer to a freeze plug or drainage plug fitting on existing traps (lower front and bottom), which is prohibited. By not clarifying the location of the trap primer connection, where freeze plugs and trap drainage plugs are located, solids and bacteria could cause unnecessary problems, such as stopping up and contaminations detrimental to the health and safety of the consumer. A trap seal must be deep enough to resist the pressures that can develop in a properly vented drainage system, but not so deep as to promote the retention of solids or the growth of bacteria. This reason alone is enough for concern to raise the trap primer connection above the water weir. 155

2 Item #: 146 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/REP Sure-Seal RECOMMENDATION: Revise text as follows: Trap Seal Protection. Floor drain or similar traps directly connected to the drainage system and subject to infrequent use shall be protected with a trap seal primer, except where not deemed necessary for safety or sanitation by the Authority Having Jurisdiction. Trap seal primers shall be accessible for maintenance. Floor drains and traps subject to evaporation due to infrequent use shall be protected with a water supplied trap seal primer, drainage supplied trap seal primer, or floor drain trap seal protection device. Water supplied trap seal primers shall be accessible for maintenance. SUBSTANTIATION: I submitted a similar change the previous cycle. Unfortunately, the standard regulating floor drain trap seal protection deices was not completed at the time. This section needs strong language to emphasize that trap seal protection is required. This is not something that is left to someone s discretion. One of the key factors in preventing the escape of sewer gas is the protection of trap seals that are subject to evaporation. Numerous articles have been published identifying loss of floor drain trap seals as a possible cause of he spread of SARS. There are three types of protection methods for trap seals: one is a water supplied device, one connects to the drain, and one provides a barrier. All three of these trap seal protection devices are listed. Furthermore, all three are regulated by standards. Hence, it is appropriate to identify that any one of the three methods is acceptable for providing trap seal protection. 156

3 Item #: 147 UPC ( ): SUBMITTER: Sidney Cavanaugh Cavanaugh Consulting/Rep. Thermaco RECOMMENDATION: Revise text as follows: Grease Interceptors Where it is determined by the Authority Having Jurisdiction that waste pretreatment is required, an approved type of grease interceptor(s) complying with the provisions of this section shall be correctly sized and properly installed in grease waste line(s) leading from sinks and drains, such as floor drains and floor sinks and other fixtures or equipment in serving establishments such as restaurants, cafes, lunch counters, cafeterias, bars and clubs, hotels, hospitals, sanitariums, factory or school kitchens, or other establishments where grease may be introduced into the drainage or sewage system in quantities that can effect line stoppage or hinder sewage treatment or private sewage disposal. A combination of interior (hydromechanical) and exterior (gravity) grease interceptors shall be allowed in order to meet grease separation needs of the Authority Having Jurisdiction when space or existing physical constraints of existing buildings necessitate such installations. A grease interceptor shall not be required for individual dwelling units or for any private living quarters. Water closets, urinals, and other plumbing fixtures conveying human waste shall not drain into or through the grease interceptor. SUBSTANTIATION: This code change recognized the need for combinations of grease interceptors for renovation projects involving existing buildings where there is insufficient space to install a large enough in-ground grease interceptor (gravity type) to meet local sewer ordinance requirements. While current code language needs a method for calculating overall separator capacity when multiple interceptors are installed, this is a move in the right direction and will helpfully open dialogue on the issue and, perhaps, generate a committee proposal or public comment to include a table for such sizing. Such as a weighing index for currently determining interior separator capacity versus the grease generating characteristics at the service point. The plumbing code currently ranks hydromechanical interceptors [mostly interior use] by a GPM rating and larger [mostly exterior] gravity interceptors by a capacity rating. A fixture grease discharge potential rating would seem to merge these into a workable table; for example, rotisserie oven [high grease discharge], wok range [moderately high grease discharge], and three-compartment pot washing sink [moderate grease discharge]. 157

4 Item #: 148 UPC (Table 10 2, ): SUBMITTER: Rand Ackroyd Chair, UPC Fog Task Group RECOMMENDATION: The following are the recommendations of the FOG Task Group (see the Fog Task Group Report #148). Item 1 Delete existing Table 10 2 and substitute as follows: Table 10 2 Hydro Mechanical Grease Interceptor (HGI) Sizing Chart* DFU HGI Flow (gpm) *Based on intermittent potentially full flow in drainage lines. Table 10 2 Hydro-mechanical Interceptor Sizing Using Gravity Flow Rates (1) Size of Grease Interceptor Diameter of Grease Maximum Full Pipe One-Minute Drainage Two-Minute Drainage Waste Pipe Flow (gpm) (2) Period (gpm) Period (gpm) (1) For interceptor sizing by fixture capacity see the example below. (2) ¼ (.240) slope per foot based on Manning s formula with friction factor N=.012 Item 2 Add new sizing example as follows: EXAMPLE FOR SIZING HYDROMECHANICAL INTERCEPTOR(S) USING FIXTURE CAPACITY Step 1: Determine the flow rate from each fixture. [Length] X [Width] X [Depth] / [231] = Gallons X [.75 fill factor] / [Drain Period (1 min or 2 min)] 158

5 Step 2: Calculate the total load from all fixtures that discharge into the interceptor. Fixtures Compartments Load (gallons) Size of Grease Interceptor One-Minute Drainage Two-Minute Drainage Period (gpm) Period (gpm) Compartment size 12 x 24 x Hydrant 3 Rated Appliance Item 3 Revise text as follows: Each plumbing fixture or piece of equipment connected to a hydromechanical grease interceptor shall be provided with discharge into an approved type of vented flow control installed in a readily accessible and visible location. Flow control devices shall be designed and installed so that the total flow through such device or devices shall at no time be greater than the rated flow of the grease interceptor. No flow-control device having adjustable or removable parts shall be approved. The vented flow-control device shall be located such that no system vent shall be between the flowcontrol and the grease trap interceptor inlet. The vent or air inlet of the flowcontrol device shall connect with the sanitary drainage vent system, as elsewhere required by this code, or shall terminate through the roof of the building, and shall not terminate to the free atmosphere inside the building. Exception: Listed grease interceptors with integral flow controls or restricting devices shall be installed in an accessible location in accordance with the manufacturers instructions. SUBSTANTIATION: Substantiation for Item 1 & 2 The actual flow in gpm per dfu is different for various fixtures. In existing Table 10 2, a dfu is equated at 2.5 gpm and another instance has a value of only 0.3 gpm. Performance standards for hydro-mechanical interceptors are based on actual peak gpm flow rate and not on average flow as compared to drainage fixture units. It is imperative that the code scientifically substantiate the result and removes any interpretive processes in sizing. The revision to Table 10 2 from dfu to gpm for sizing hydro-mechanical grease interceptors provides correlation with published consensus standards ASME A and PDI G101. The logical starting point is to base the size of the interceptor on the actual gallons per minute produced by the fixtures or, the size of the drainpipe leaving the establishment or the inlet of the interceptor. Without this revision to Table 10 2, current sizing methods permit undersized hydro-mechanical grease interceptors installed in various establishments. Substantiation for Item 3 The revision to Section provides a clarification that a vent flow control device is not required for each plumbing fixture but rather each fixture or equipment discharges into an approved type vented flow control device. this device is installed upstream from the interceptor that controls the rate of flow through the interceptor and a vent downstream, which allows air to be drawn into the flow stream and must be installed in accordance with the manufacturer s installation instructions thereby, negating the misconception. 159

Drainage Fixture Units 160

7 (DFU) are not an acceptable tool for sizing grease interceptors because DFU s are an averaging device based on intermittent flow estimations used to size drainage piping and so not provide precise statement of maximum flow possible. The DFU values in the current chart are not consistent either with this code, or the gpm rating within the chart [mathematically incorrect] and result in dangerously undersized interceptors. Current chart is inconsistent with ASME A dictating HGI performance, rating and sizing. This proposal is not original material; its reference/source is as follows: ASME A

8 Item #: 150 UPC (Table 10 2): SUBMITTER: Rand Ackroyd Rand Engineering RECOMMENDATION: Revise tables as follows: Delete existing Table 10 2 and substitute as follows: Table 10 2 Hydro Mechanical Grease Interceptor (HGI) Sizing Chart* DFU HGI Flow (gpm) *Based on intermittent potentially full flow in drainage lines.

10 Item #: 151 UPC ( , Table 10 3): SUBMITTER: Max Weiss Weiss Research RECOMMENDATION: Revise text as follows: Sizing Criteria Sizing. The volume of the interceptor shall be determined by using Table If drainage fixture units (DFUs) are not known, the interceptor shall be sized based on the maximum DFUs allowed for the pipe size connected to the inlet of the interceptor. Refer to Table 7 5, Drainage Piping, Horizontal. Table 10 3 Gravity Grease Interceptor Sizing DFUs (1) Interceptor Volume (2) gallons 21 (3) 750 gallons 35 1,000 gallons 90 (3) 1,250 gallons 172 1,500 gallons 216 2,000 gallons 307 (3) 2,500 gallons 342 3,000 gallons 428 4,000 gallons 576 5,000 gallons 720 7,500 gallons ,000 gallons ,000 gallons Notes (1) The maximum allowable DFUs plumbed to the kitchen drain lines that will be connected to the grease interceptor. (2) This size is based on: the DFUs, the pipe size from this code; Table 7 5; Useful Tables for flow in half-full pipes (ref: Mohinder Nayyar Piping Handbook, 3rd Edition, 1992). (3) Based on 30-minute retention time (ref.: Metcalf & Eddy, Inc. Small and Decentralized Wastewater Management Systems, 3rd Ed. 1998). Rounded up to nominal interceptor volume. Gravity Grease Interceptor Sizing Example: Given: A restaurant with the following fixtures and equipment. One food preparation sink; three floor drains one in the food prep area, one in the grill area, and one receiving the indirect waste from the ice machine; a mop sink; a dishwasher with a maximum discharge flow rate of 20 gpm discharging into a dedicated receptor; and two public restrooms, each with one water closet and one lavatory. Kitchen Drain Line DFU Count (from Table 7 3): 3 floor 2 DFUs each = 6 DFUs Mop 3 DFUs each = 3 DFUs Food prep 3 DFUs each = 3 DFUs 4 DFUs (Table 7 4) = 4 DFUs Total 16 DFUs Using Table 10 3, the grease interceptor will be sized at 750 gallons. TABLE 10 3 GRAVITY INTERCEPTOR SIZING DISCHARGE SIZING USING FIXTURE CAPACITY Calculation of fixture capacity: [Length} X [Width] X [Depth] / [231] = Gallons X [.75 fill factor] / [Drain Period (1 or 2)] Add hydrant capacity (gpm supply to faucet); Add rated appliances such as dishwasher, water wash hood at manufacturers ratings. 164

11 EXAMPLE: Fixture Compartment Size Compartments Load,gal 24x24x Total hydrant supply and rated discharges Total Discharge The selection listed is based on application of the sizing formula above. DISCHARGE SIZING USING PIPE SIZE & SLOPE Pipe Dia. Slope/Ft. (1) Full Pipe Flow (2) gpm gpm gpm gpm gpm (1) Inches drop per foot of run (Total vertical distance from atmospheric to invert of interceptor divided by length of pipe.) (2) Based on Mannings formula with friction factor N=.012; CAST IRON SOIL PIPE AND FITTINGS HANDBOOK; Ch 8, Flow Theory And Capacity; pp: [Full Pipe]; Cast iron Soil Pipe Institute (CISPI); 5959 Shallowford Road, Suite 419; Chattanooga, TN GRAVITY INTERCEPTOR SIZING Multiply the result of either Fixture Capacity or Pipe Size (above) by 30 to reflect required retention time (3). Ex gpm X 30 = 1,760 gal. capacity. (Using fixture content above to calculate maximum fixture capacity). Ex gpm X 30 = 1,760 gal. capacity. (Using 3 pipe slope to calculate maximum pipe capacity). (3) Based on 30 minute retention time (ref. Metcalf & Eddy Inc. 3 rd Edition. Small and Decentrailized Wastewater Management Systems 1998). SUBSTANTIATION: Current sizing methods in this code for gravity and hydromechanical grease interceptors requires one facility to discharge different volumes at different velocities depending on the type of interceptor connected obviously an unintended consequence of calculating from the interceptor to the facility. Grease interceptors must be sized to peak flow calculation to avoid scouring contents and or creating conduit flow through the interceptor. Drainage Fixture Units (DFU) are not acceptable tools for sizing grease interceptors because DFU s are an averaging device based on intermittent flow estimations used to size drainage piping and do not provide a precise statement of maximum flow possible from a given facility. All facilities discharge at peak flow all they are capable of discharging or all the connected drain is capable of carrying. The type of interceptor connected does not alter the facility discharge. Peak facility discharge is measured in and expressed as gallons per minute (gpm) and liters per minute (l/pm). Gravity interceptors retain a given number of gallons for a given number of minutes; the gallons must be the peak demand from the facility. The minutes of retention are designated by the AHJ. 165

13 EXAMPLE: Fixture Compartment Size, in. Compartments Load,gal Recommended Interceptor Size, Based on 30 minute retention time Rounded up to the next nominal size 24x24x gallons SUBSTANTIATION: It was never the intent of a DFU in the Code to have a direct equivalent in GPM. The actual flow in GPM per DFU is different for different fixtures. In Table 10 3 a DFU is equated at 2.5 GPM in one instance and a DFU in another instance has a value of only 0.3 GPM! The GPM's associated with DFU's is different for the each size interceptor within the Table This is obviously a serious flaw in introducing DFU's into this table for sizing. All the performance standards for interceptor design and performance are based on actual peak GPM flow. DFU's are an average flow, not peak flows. It is imperative that the CODE "be able to scientifically substantiate the result." The correction is simple, replace DFU's with actual peak GPM's for sizing. It is logical to simply base the size of the interceptor on the maximum gallons per minute flow of the drain pipe leaving the establishment entering the inlet of the interceptor. A retention time of 30 minutes is widely recognized for sizing gravity interceptors. 167

14 Item #: 153 UPC ( ): SUBMITTER: Max Weiss Weiss Research RECOMMENDATION: Revise text as follows: Hydromechanical Grease Interceptors Each All plumbing fixtures or piece of equipment connected to a hydromechanical grease interceptor shall be provided with discharge through an approved type of vented flow control installed in a readily accessible and visible location. Flow control devices shall be designed and installed so that the total flow through such device or devices shall at no time be greater than the rated flow of the connected grease interceptor. No flowcontrol device having adjustable or removable parts shall be approved. The vented flow-control device shall be located such that no system vent shall be between the flow control and the grease trap inlet. The vent or air inlet of the flow-control device shall connect with the sanitary drainage vent system, as elsewhere required by this code, or shall terminate through the roof of the building, and shall not terminate to the free atmosphere inside the building. Exception: Listed grease interceptors with integral flow controls or restricting devices shall be installed in an accessible location in accordance with the manufacturers instructions. SUBSTANTIATION: As currently worded each fixture would be required to have a separate flow control dedicated to that fixture. That was not the TG intent. The intent was to ensure all connected fixtures discharged through the flow control and the aggregate flow did not exceed the rating of the interceptor. Originally discussed in the assigned Task Group. This proposal is not original material; its reference/source is as follows: Originally discussed in the assigned Task Group 168

15 Item #: 154 UPC ( (New) ): SUBMITTER: Sherrill Bond City of Los Angeles, Industrial Waste Management Division, FOG Program RECOMMENDATION: Add new text as follows: Sizing Criteria Sizing. The volume of the interceptor shall be determined by using Table If drainage fixture units (DFUs) are not known, the interceptor shall be sized based on the maximum DFUs allowed for the pipe size connected to the inlet of the interceptor. Refer to Table 7 5, Drainage Piping, Horizontal Additional Sizing Factors. To allow for adequate grease storage capacity, the Authority Having Jurisdiction may require the gravity grease interceptor size to be increased by a factor of 1.5 for 12 hours of operation, 2 for 16 hours of operation and 3 for 24 hours of operation when food is prepared on-site using grills, fryers, wok ranges, barbecues, or similar devices causing grease waste to be generated. SUBSTANTIATION: The 2006 UPC does not consider the grease waste loading as relevant to sizing the gravity grease interceptor (GGI). Consequently, the 2006 sizing method may result in an insufficient grease storage capacity and therefore require an excessively high GGI cleaning frequency. Ultimately, cleaning and maintenance charges can be saved when sizing the GGI. 169

16 Item #: 155 UPC (Table 11 1 (New)): SUBMITTER: Matt Bell d.b.a. Plumbing Systems Design RECOMMENDATION: Delete Table 11 1 and footnotes and substitute as follows: TABLE 11 1 Sizing Roof Drains, Leaders, and Vertical Rainwater Piping 2, 3 Size of Drain, Maximum Allowable Horizontal Projected Roof Areas Leader, or Pipe, Flow, Inches gpm1 Square Feet at Various Rainfall Rates 1in./h 2 in./h 3 in./h 4 in./h 5 in./h 6 in./h 7 in./h 8 in./h 9 in./h 10 in./h 11 in./h 12 in./h ,880 1, ,800 4,400 2,930 2,200 1,760 1,470 1,260 1, ,400 9,200 6,130 4,600 3,680 3,070 2,630 2,300 2,045 1,840 1,675 1, ,600 17,300 11,530 8,650 6,920 5,765 4,945 4,325 3,845 3,460 3,145 2, ,000 27,000 17,995 13,500 10,800 9,000 7,715 6,750 6,000 5,400 4,910 4, ,000 58,000 38,660 29,000 23,200 19,315 16,570 14,500 12,890 11,600 10,545 9,600 TABLE 11 1 (Metric) 2, 3 Sizing Roof Drains, Leaders, and Vertical Rainwater Piping Size of Drain, Maximum Allowable Horizontal Projected Roof Areas Leader or Square Meters at Various Rainfall Rates Pipe, Flow, mm L/s mm/h mm/h mm/h mm/h mm/h mm/h mm/h mm/h mm/h mm/h mm/h mm/h , , , , , , , , , , Notes: 1. Maximum discharge capacity, gpm (L/s) with approximately 13/4-inch (44.5 mm) head of water at the drain. 2.For rainfall rates other than those listed, determine the allowable roof area by dividing the area given in the 1-inch/hour (25 mm/hour) column by the desired rainfall rate. 3.Vertical piping may be round, square, or rectangular. Square pipe shall be sized to enclose its equivalent round pipe. Rectangular pipe shall have at least the same cross-sectional area as its equivalent round pipe, except that the ratio of its side dimensions shall not exceed 3 to 1. SUBSTANTIATION: During the amalgamation process from the 1994 UPC to the 1997 UPC, the original roof leader in Table 11 1 was replaced with a Table from an unknown source. The values given for gpm and tributary areas were reduced and sizing data for vertical conductors, leaders and drains were based on the pipes flowing 7/24 full. In order to provide consistency based on the sizing methods that have not changed in over 12 years this proposed table for sizing roof drains, leaders and vertical rainwater piping is based on the 1994 UPC and the current ASPE Data Book. In comparing with other model codes the same tributary areas and gpm flow rate is identical. 170

17 Item #: 156 UPC ( ): SUBMITTER: Matt Bell d.b.a. Plumbing Systems Design RECOMMENDATION: Revise text as follows: Combined System. The secondary roof drains shall connect to the vertical piping of the primary storm drainage conductor downstream of any horizontal offset below the roof. A flow sensor or other approved method of identifying flow shall be installed in the secondary drain line before it connects to the primary line. The sensor or other approved method of identifying flow shall notify building maintenance if there is any flow in the secondary system. The primary storm drainage system shall connect to the building storm water that connects to an underground public storm sewer. The combined secondary and primary roof drain systems shall be sized in accordance with Section based on double the rainfall rate for the local area. SUBSTANTIATION: The current language of 2006 UPC does not have any provision for the maintenance personnel to observe flow from the secondary system, as you would in a separate system. Part of the intent of a secondary roof drain system is to identify problems with the primary roof drain system, by the observance of flow from the secondary system, so he maintenance personal can address and correct the problem. Adding the proposed language will satisfy that intent. 171

18 Item #: 157 UPC ( (New), Table 14 1): SUBMITTER: Robert Evans American Society of Plumbing Engineers RECOMMENDATION: Add new text as follows: Siphonic Roof Drainage System. A siphonic roof drainage system shall be designed in accordance with ASPE 45. MANDATORY REFERENCED STANDARDS TABLE 14 1 Standards for Materials, Equipment, Joints, and Connections Where more than one standard has been listed for the same material or method, the relevant portions of all such standards shall apply. Standard Number Standard Title Application ASPE Siphonic Roof Drainage System Design Manual (Note: Standard not included with proposal) SUBSTANTIATION: ASPE has published a new standard for siphonic roof drainage systems. this standard provides the design criteria that must be followed for the proper operation of a siphonic roof drainage system. By referencing this new standard, the Authority Having Jurisdiction will understand which standard to follow when evaluating a siphonic roof drainage system. 172

19 Item #: 158 UPC ( , ): SUBMITTER: Michael Cudahy Plastic Pipe and Fitting Association (PPFA) RECOMMENDATION: Revise text as follows: Methods of Testing Storm Drainage Systems. Except for outside leaders and perforated or openjointed drain tile, the piping of storm drain systems shall be tested upon completion of the rough piping installation by water or air, except that plastic pipe shall not be tested with air, and proved tight. The Authority Having Jurisdiction may require the removal of any cleanout plugs to ascertain whether the pressure has reached all parts of the system. Either One of the following test methods shall be used: Water Test. After piping has been installed, the water test shall be applied to the drainage system, either to the entire system or to sections. If the test is applied to the entire system, all openings in the piping shall be tightly closed except for the highest opening, and the system shall be filled with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged except for the highest opening of the section under test, and each section shall be filled with water, but no section shall be tested with less than a ten (10) foot (3,048 mm) head of water. In testing successive sections, at least the upper ten (10) feet (3,048 mm) of the next preceding section shall be tested so that no joint of pipe in the building (except the uppermost ten (10) foot (3,048 mm) of a roof drainage system, which shall be filled with water to the flood level of the uppermost roof drain) shall have been submitted to a test of less than a ten (10) foot (3048 mm) head of water. The water shall be kept in the system or in the portion under test for at least fifteen (15) minutes before inspection starts; the system shall then be tight at all points Air Test. The air test shall be made by attaching an air compressor testing apparatus to any suitable opening after closing all other inlets and outlets to the system, forcing air into the system until there is a uniform gauge pressure of five (5) psi (34.5 kpa) or sufficient pressure to balance a column of mercury ten (10) inches (254 mm) in height. This pressure shall be held without introduction of additional air for a period of at least fifteen (15) minutes. Schedule 40 plastic DWV systems shall not be tested by the air test method. SUBSTANTIATION: The existing language varies from language used in previous sections of the code. This change brings this section into a similar format regarding air testing of plastic pipe. 173

20 Item #: 159 UPC ( (New)): SUBMITTER: John Rattenbury Rainwater Management Solutions RECOMMENDATION: Add new text as follows: Siphonic Roof Drainage Permitted. Engineered siphonic roof drainage systems shall be permitted provided that the submitted design and documentation complies with Section and ASPE Siphonic Roof Drains. Siphonic roof drains shall comply with the provisions of ASME A Pipe and Fittings. Pipe and fittings used for siphonic roof drainage systems shall comply with Section , and ASPE 100. Plastic pipe and fittings shall be designed and installed in accordance with ASTM F SUBSTANTIATION: Siphonic roof drainage is a mature and time-proven technology with many thousands of installations around the world and a growing number in the United States. IAPMO Research and Testing recognizes and acknowledges the efficiency of the technology through siphonic roof drain product listing (see attached Listing Certificate for one product) and the existence of ASME A Siphonic Roof Drains as the qualifying product standard. However, despite these facts and the fact that the UPC permits alternative engineered systems in Section 301.2, many local plumbing inspectors are reluctant to give consent for engineered systems not specifically addressed in the body of the Code simply because they don t understand them. By including the proposed sub-section to Chapter 11 Storm Drainage, we hope local code enforcement officials will have better guidance and direction through referenced standards and IAPMO s acknowledgment of the technology. 174

21 Item #: 160 UPC (TIA UPC Chapter 12): SUBMITTER: Joseph A. Sternola Permagas Inc. RECOMMENDATION: Revise text as follows: General. The regulations of this chapter shall govern the installation of all fuel gas piping in or in connection with any building or structure or within the property lines of any premises up to 5 psi, other than service pipe. Fuel oil piping systems shall be installed in accordance with NFPA 31. Exception: Gas piping, meters, gas-pressure regulators, and other appurtenances used by the serving gas supplier in distribution of gas, other than undiluted LP-Gas [NFPA 54: (16)] The following regulations, as set forth in this section and in Section , Required Gas Piping Size, shall be the standard for the installation of gas piping. All natural gas regulations and tables are based on the use of gas having a specific gravity of sixty hundredths (0.60), supplied at six (6) to eight (8) inches ( mm) water column pressure at the outlet of the meter or regulator. Where the natural gas supplier cannot maintain a minimum inlet pressure of six (6) inches (152 mm) water column pressure, Table 12 7 allowing a maximum pressure drop of 0.3-inch (7.6 mm) water column shall be used. For undiluted liquefied petroleum gas, gas piping may be sized for 2,500 Btu per cubic foot (25.9 Watt-hours/L) at eleven (11) inches (279 mm) water column pressure at the outlet of the meter or regulator and specific gravity of one and fifty-two hundredths (1.5250) Where the maximum demand does not exceed two hundred fifty (250) cubic feet per hour (2 L/sec.) and the maximum length of piping between the meter and the most distant outlet is not over two hundred fifty (250) feet (76,200 mm), the size of each section and each outlet of any system of gas piping shall be determined by means of Table 12 7 for steel pipe, or Table for copper tubing systems, or Table for CSST systems. Other Systems within the range of Table 12 7 or or Table may be sized from that table or by means of the methods set forth in Section Pipe Sizing Methods Where the pipe size is to be determined using any of the methods in Sections through , the diameter of each pipe segment shall be obtained from the pipe-sizing tables in Section or from the sizing equations in Section [NFPA 54: 6.1] Longest Length Method. The pipe size of each section of gas piping shall be determined using the longest length of piping from the point of delivery to the most remote outlet and the load of the section (see calculation example in Figure 12 2). [NFPA 54: 6.1.1] Branch Length Method. Pipe shall be sized as follows: [NFPA 54: 6.1.2] (A) Pipe size of each section of the longest pipe run from the point of delivery to the most remote outlet shall be determined using the longest run of piping and the load of the (B) section. The pipe size of each section of branch piping not previously sized shall be determined using the length of piping from the point of delivery to the most remote outlet in each branch and the load of the section Hybrid Pressure. The pipe size for each section of higher-pressure gas piping shall be determined using the longest length of piping from the point of delivery to the most remote line pressure regulator. The pipe size from the line pressure regulator to each outlet shall be determined using the length of piping from the regulator to the most remote outlet served by the regulator. [NFPA 54: 6.1.3] Tables for Sizing Gas-Piping Systems. Tables 12 7 through shall be used to size gas piping in conjunction with one of the methods described in Sections through [NFPA 54: 6.2,6.3] Sizing Equations. The inside diameter of smooth-wall pipe or tubing shall be determined by the sizing equations 12 1 or 12 2, using the equivalent pipe length determined by Sections through [NFPA 54: 6.4] Equation 12 1 Low-Pressure Gas Formula (Less than 1.5 psi [10.3 kpa]): [NFPA 54: 6.4.1] (Remains unchanged.) Equation 12 2 High-Pressure Gas Formula (1.5 psi [10.3 kpa] and above): [NFPA 54: 6.4.2] ( Remains unchanged.) Table 12 4 Cr and Y for Natural Gas and Undiluted Propane at Standard Conditions [NFPA 54: Table 6.4.2] 175

22 (To be renumbered accordingly.) Figure 12 2 Example Illustrating Use of Tables 12 1 and Solution: (1) Maximum gas demand of outlet A - 32 cubic feet per hour (0.21 L/sec.) (from Table 12 1). Maximum gas demand of outlet B - 3 cubic feet per hour (0.02 L/sec.) (from Table 12 1). Maximum gas demand of outlet C - 59 cubic feet per hour (0.46 L/sec.) (from Table 12 1). Maximum gas demand of outlet D cubic feet per hour (1.1 L/sec.) (150,000 Btu/hour [43,950 W]) divided by 1,100 Btu per cubic foot (11.4 Watt-hour/L) (2) The length of pipe from the gas meter to the most remote outlet (outlet A) is 60 feet (18,288 mm). (3) Using the length in feet column row marked 60 feet (18,288 mm) in Table 12-78: Outlet A, supplying 32 cubic feet per hour (0.21 L/sec.), requires one-half (1/2) inch (15 mm) pipe. Section 1, supplying outlets A and B, or 35 cubic feet per hour (0.24 L/sec.) requires one-half (1/2) inch (15 mm) pipe. Section 2, supplying outlets A, B, and C, or 94 cubic feet per hour (0.7 L/sec.) requires three-quarter (3/4) inch (20 mm) pipe. Section 3, supplying outlets A, B, C, and D, or 230 cubic feet per hour (1.8 L/sec.), requires one and one quarter (1-1/4) inch (32 25 mm) pipe. (4) Using the column marked 60 feet (18,288 mm) in Table (no column for actual length of 55 feet [16,764 mm]: Outlet B supplying 3 cubic feet per hour (0.02 L/sec.), requires one-half (1/2) inch (15 mm) pipe. Outlet C, supplying 59 cubic feet per hour (0.46 L/sec.), requires one-half (1/2) inch (15 mm) pipe. (5) Using the column marked 50 feet (15,240 mm) in Table : Outlet D, supplying 136 cubic feet per hour (1.1 L/sec.), requires (1 3/4) inch (25 20 mm) pipe To determine the size of each section of pipe in any system within the range of the Table 12 7, proceed as follows: (1A) Measure the length of the pipe from the gas meter location to the most remote outlet on the system. (2B) In Table 12 7 sselect the length in feet column and row showing that distance, or the next longer distance if the table does not give the exact length. (3C) Starting at the most remote outlet, find in the row just selected the gas demand for that outlet. If the exact figure of demand is not shown, choose the next larger figure in the row. (4D) At the top of this column will be found the correct size of pipe. (5E) Using this same row, proceed in a similar manner for each section of pipe serving this outlet. For each section of pipe, determine the total gas demand supplied by that section. Where gas piping sections serve both heating and cooling equipment and the installation prevents both units from operating simultaneously, only the larger of the two demand loads needs to be used in sizing these sections. (6F) Size each section of branch piping not previously sized by measuring the distance from the gas meter location to the most remote outlet in that branch and follow the procedures of steps 2 B, 3 C, 4 D, and 5 E above. Note: Size branch piping in the order of their distance from the meter location, beginning with the most distant outlet not previously sized For conditions other than those covered by Section , such as longer runs or greater gas demands, the size of each gas piping system shall be determined by standard engineering methods acceptable to the Authority Having Jurisdiction, and each such system shall be so designed that the total pressure drop between the meter or other point of supply and any outlet when full demand is being supplied to all outlets, will at no time exceed five-tenths (0.5) inches (12.7 mm) water column pressure Where the gas pressure may be higher than fourteen (14) inches (356 mm) or lower than six (6) inches (152 mm) of water column, or when diversity demand factors are used, the design, pipe, sizing, materials, location, and use of such systems first shall be approved by the Authority Having Jurisdiction. Piping systems designed for pressures higher than the serving gas supplier's standard delivery pressure shall have prior verification from the gas supplier of the availability of the design pressure. Systems using undiluted liquefied petroleum gas may be sized using Table for steel pipe and Table for CSST for eleven (11) inches (279 mm) of water column and in accordance with the provisions of Sections and For copper tubing systems using undiluted liquefied petroleum gas, the capacity of the tubing shall be determined by multiplying the values of Table by the appropriate factor from Table

23 SUBSTANTIATION: Technical Merit: 1. The exception to section is a duplication and is not required. 2. Table 12 7 allowing a maximum pressure drop of 0.3-inch water column was added to the code without any explanation or reason for the addition. If this table was routinely used in would result in oversizing of the system. The 2500 BTU per cubic foot heating value for LPG was removed from NFPA 54 and is not required for sizing an LPG system. All the new LPG tables in the code reflect a specific gravity of one and fifty hundredths (1.50). 3. Section is no longer applicable to the new tables in the code. The designer of the system must select the table which best describes the piping material and the source of gas supplied. Section through Section including equations 12 1 and 12 2 are relocated to Section so that pipe sizing is covered in one location in the code instead of two. 4. Figure 12 2 Example Illustrating the use of Table 12 1 and 12 7 is amended to illustrate the use of Table 12 8 which provide for a pressure drop of 0.5 inches water column. This is the most commonly used table instead of Table 12 7 which as stated in the amended Section is for systems that cannot supply a minimum pressure of six (6) inches water column pressure. 5. Section is amended to remove reference to any specific table as the method described would apply to all of the tables. Section is amended to remove the last two sentences as separate tables for LPG are now provided. Emergency Nature: In processing the 2006 edition, tables were added, taken from NFPA 54, National Fuel Gas Code. As these tables cover a greater number of conditions, such as pressure and pressure drop, which were not previously included in the Uniform Plumbing Code. The changes to the UPC are needed to explain the use of these new tables. (Below are the Council Comments) The Council notes that the identical changes are proposed to the 2006 edition of the Uniform Mechanical Code in proposed TIA-UMC and the Council addresses both requests simultaneously. Proposed TIA UPC was balloted through the Plumbing Technical Committee in accordance with the Regulations Governing Committee Projects to determine if there existed the necessary three-forths majority support on technical merit and emergency nature to establish the recommendation for issuance. In each case, the letter ballot failed to achieve the required three-forths majority to establish the recommendation for issuance although a majority of committee members voted to recommend the issuance of the TIA on both accounts. The identical issue was presented to the Mechanical Technical Committee who recommended by three-forths majority on both accounts to issue TIA-UMC In determining whether or not to issue a TIA, the Council looks to the TC letter ballot for a recommendation of support, which was not achieved by the Plumbing TC in this instance. Notwithstanding the absence of a clear recommendation by the Plumbing TC, the Council agrees by unanimous vote that the substantial reasons exist for the issuance of the TIA requested by proponent. The Council is persuaded by the compelling argument made by the proponent within the body of the proponent s submission and notes that the issuance of this TIA will serve to further harmonize the 2006 edition of the Uniform Plumbing Code with the National Fuel Gas Code. The Council concurs with the substantiation set forth by the proponent and after a full review and consideration of all of the information available to it, the Council voted to issue proposed TIA UPC (attached). Parenthetically, the Council also notes the issuance of TIA UMC placing the identical language into the 2006 edition of the Uniform Mechanical Code. 177

24 Item #: 161 UPC ( ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: Gas-Piping System Any arrangement of gas piping supplied by one (1) meter or pressure regulator, and each arrangement of gas piping serving a building, structure, or premises, whether individually metered or not. SUBSTANTIATION: The current definition excludes most systems where propane is the fuel, as they do not have a meter. 178

25 Item #: 162 UPC ( ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: (Revise Section 1209 by identifying the following paragraphs as extracts from NFPA 54:) [NFPA 54: 5.1.1] [NFPA 54: 5.1.2] [NFPA 54: 5.2] [NFPA 54: 5.3] [NFPA 54: 5.3.1] [NFPA 54: 5.3.2] [NFPA 54: 5.4] [NFPA 54: 5.4.1] [NFPA 54: 54.2] Exception: [NFPA 54: 54.2] [NFPA 54: (1)] [NFPA 54: (2)] [NFPA 54: (3)] SUBSTANTIATION: These paragraphs extracted from NFPA 54 are not identified in the 2006 edition. This omission is corrected with this proposal. This proposal is not original material; its reference/source is as follows: NFPA 99, Standard for Health Care Facilities 179

26 Item #: 163 UPC ( , Table 14 1 (New)): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/REP Viega NA RECOMMENDATION: Add new text as follows: Copper Press Connection Joints. Copper press connection fittings shall comply with ANSI LC-4. (Renumber remaining sections) MANDATORY REFERENCED STANDARDS TABLE 14 1 Standards for Materials, Equipment, Joints, and Connections Where more than one standard has been listed for the same material or method, the relevant portions of all such standards shall apply. Standard Number Standard Title Application ANSI LC-4 Press-Connect Copper and Copper Fittings Alloy Fittings For use in Fuel Gas Distribution Systems SUBSTANTIATION: ANSI LC-4 is the latest standard for coper press connection fittings for use in gas piping systems. This change adds the appropriate reference to Chapter 12 and the standard reference to Table

27 Item #: 164 UPC ( ): SUBMITTER: Philip Campbell UA Training Specialist RECOMMENDATION: Revise text as follows: Plastic Piping, Joints, and Fittings. Plastic pipe, tubing, and fittings shall be joined in accordance with the manufacturers' instructions. The following shall be observed when making such joints: [NFPA 54: 5.6.9] (A) No change (B) Heat-fusion joints shall be made in accordance with qualified procedures that have been established and proven by test to produce gastight joints at least as strong as the pipe or tubing being joined AWS B2.4 Specification for Welding Procedure and Performance Qualification for Thermoplastics. Joints shall be made with the joining method recommended by the pipe manufacturer. Heat-fusion fittings shall be marked ASTM D (C) No change (D) No change SUBSTANTIATION: The referenced standard AWS B2.4 Specification for Welding Procedures and Performance Qualification for Thermoplastics was approved by ANSI on February 16, The standard was prepared by AWS B2 Committee on Welding Qualification, which consists of many knowledgeable volunteers from the mechanical and thermoplastics industries, representing varied viewpoints and interests to achieve consensus. The various methods of welding thermoplastics pipe and fittings are now becoming widely used for joining such pipe and fittings. The code currently does not provide adequate requirements to ensure that these installations are being performed using recommended methods by qualified installers. 181

28 Item #: 165 UPC ( ): SUBMITTER: Robert Torbin Cutting Edge Solutions LLC RECOMMENDATION: Delete text without substitution: Excess Flow Valve. When automatic excess flow gas shutoff devices (valves) are used, they shall be listed and approved and shall be sized for the maximum flow anticipated for the main or branch of the fuel gas system in which the excess flow valve is installed. SUBSTANTIATION: I am currently performing an engineering study and computer simulations on EFV and bypass flow. The results to date indicate that the bypass feature will create a secondary hazard of equal danger to the consumer as having no EFV at all. In other words, the gas leakage through the valve (when installed in a confined space such as a utility closet) will allow a plume to form and reach the LEL in a short period of time. The automatic reset feature is permitted by the EFV standard, which permits up to 10-scfh of gas to pass through the EFV even after it has been activated. The use of EFV should be prohibited until such time as the bench standard is upgraded to a nationally recognized standard, and the bypass feature is either significantly reduced or eliminated from the standard. As currently designed and operated, the EFV is a potentially dangerous device, but sold as a safety improvement. Research result will be presented at the Technical Committee meeting. 182

29 Item #: 166 UPC ( ): SUBMITTER: Bryan Popp Dormont Manufacturing Company RECOMMENDATION: Delete text without substitution: Excess Flow Valve. When automatic excess flow gas shutoff devices (valves) are used, they shall be listed and approved and shall be sized for the maximum flow anticipated for the main or branch of the fuel gas system in which the excess flow valve is installed. SUBSTANTIATION: There is no consensus standard to which these devices are listed. There are complex and potentially dangerous issues associated with recognizing and allowing these nonstandard devices in the fuel piping system. These issues include but are not limited to: a misperception that the excess flow valve closes or shuts-off the flow of gas; nuisance trips associated with flow surges and improper installation; many current designs can be installed backwards; failure to trip without adequate pressure drop; no consensus standard for design certification for intended temperature range and no consensus standard for durability. 183

30 Item #: 167 UPC ( ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: Systems Containing Flammable Gas-Air Mixtures. Systems containing flammable gas-air mixtures shall be in accordance with NFPA 54. SUBSTANTIATION: Flammable gas-air piping systems are rare, and usually are engineered, or part of proprietary industrial machinery. As such they will rarely be encountered by plumbers and code officials and are thus the specific requirements can be referenced to NFPA 54 rather than repeating them in the UPC. 184

31 Item #: 168 UPC ( ): SUBMITTER: William Rich Omegaflex, Inc. RECOMMENDATION: Revise text as follows: Electrical Bonding and Grounding. (A) Each aboveground portion of a gas piping system that is likely to become energized shall be electrically continuous and bonded to an effective ground-fault current path. Gas piping shall be considered to be bonded when it is connected to gas utilization equipment that is connected to the equipment grounding conductor of the circuit supplying that equipment. [NFPA 54: ] (A) Gas piping systems shall be bonded to the electrical service grounding electrode systems downstream from the point where the gas service enters the building. The bonding jumper shall not be smaller than 6 AWG copper wire. (B) No change SUBSTANTIATION: This proposal will increase the safety of the gas piping system, life safety for the building occupants and the public. Bonding of the gas piping system to the building ground has long been a requirement of the National Electrical Code and more recently the UPC; the provision that the equipment grounding conductor shall be permitted to serve as the bonding means disregards the fact that the equipment rounding wire is not sufficient to handle voltages imposed by lighting, line surges or unintentional contact with higher voltage lines which may be imposed upon the electrical grounding system (NFPA 70 Art ) The current bonding provision of the UPC can provide only potential protection and falls short of long established bonding practice for water piping and other metallic mechanical systems. A low impedance bonding conductor for the gas piping is necessary to safely down lightning energy once it has entered the building and to protect the gas piping system. 185

32 Item #: 169 UPC ( (New) ): SUBMITTER: Richard Sekerchak Dormont Manufacturing Co. RECOMMENDATION: Add new text as follows: Connecting Gas Equipment. Gas utilization equipment shall be connected to the building piping in compliance with Sections and by one of the following: [NFPA 54: 9.6.1] (1) (7) no changes (8) Commercial Cooking Appliances. Commercial cooking appliances that are moved for cleaning and sanitation purposes shall be connected in accordance with the connector manufacturer s installation instructions using a listed appliance connector complying with Z21.69 SUBSTANTIATION: Connectors that not are reinforced are being used to connect stationary appliances (appliances on legs) and on counter-top appliances. Damage is being reported with this installation arrangement due to the movement for cleaning and related activities. Reinforced connectors provide a significant increase to resistance to damage and with the installation of restraining devices thereby reducing the forces imparted to the connector. The proposed text requires movable appliance connectors for commercial cooking appliances that can be moved. The intent is to address issues with damage when using non-reinforced connectors (safety related issues). Additional Note: This text has been accepted by the National Fuel Gas Code (NFPA 54) and by the International Fuel Gas Code Committee. Acceptance will make codes consistent along with a consistent level of safety across the United States. 186

33 Item #: 170 UPC ( (6) ): SUBMITTER: Bryan Popp Dormont Manufacturing Company RECOMMENDATION: Revise text as follows: Connecting Gas Equipment. Gas utilization equipment shall be connected to the building piping in compliance with Sections and by one of the following: [NFPA 54: 9.6.1] (1) Rigid metallic pipe and fittings. (2) Semirigid metallic tubing and metallic fittings. Aluminum alloy tubing shall not be used in exterior locations. (3) Listed flexible gas connectors in compliance with ANSI Z21.24, Standard for Connectors for Gas Appliances. The connector shall be used in accordance with the terms of their listing that are completely in the same room as the equipment. (4) CSST where installed in accordance with the manufacturer's instructions. (5) Listed nonmetallic gas hose connectors in accordance with (6) Gas-fired food service (commercial cooking) equipment listed for use with casters or otherwise subject to movement for cleaning, and other large and heavy gas utilization equipment that can be moved, shall be connected in accordance with the connector manufacturer's installation instructions using a listed appliance connector complying with ANSI Z21.69, Standard for Connectors for Movable Gas Appliances. Appliances with casters shall have a restraining device that limits the movement. [NFPA 54: ] (7) In (2), (3), and (5), the connector or tubing shall be installed so as to be protected against physical and thermal damage. Aluminum alloy tubing and connectors shall be coated to protect against external corrosion where they are in contact with masonry, plaster, or insulation or are subject to repeated wettings by such liquids as water (except rain water), detergents, or sewage. SUBSTANTIATION: The additional sentence clarifies that a restraining device is required for caster mounted movable appliances. This proposed language increases safety by reducing the risk of fugitive fuel gas from improperly used connectors, potential fires and subsequent losses in commercial kitchens. Specific improvements include: 1. Reducing dangerous strain on improperly applied connectors in the commercial kitchen. 2. Increases the likelihood that manufacturer s instructions will be safely followed. 3. Increases awareness among designers, installers, users and code officials that restraining devices are required for the safe use of caster mounted movable appliances. This proposal closely matches existing language in NFPA 54 and a current proposal to NFPA

34 Item #: 171 UPC ( (New) ): SUBMITTER: Bryan Popp Dormont Manufacturing Company RECOMMENDATION: Add new text as follows: Commercial Cooking Appliance Gas Supply Orientation. The building gas supply outlet for a commercial cooking appliance shall be installed as follows: (1.) The gas supply outlet connection shall be installed in the vertical position. (2.) The bottom of the gas supply outlet connection shall be located not less than 30 (762 mm) inches above the finished floor. (3.) The gas supply outlet connection shall be directly behind the appliance it serves and not obstructed. (Renumber remaining sections) SUBSTANTIATION: The proposed language will improve the likelihood that a commercial cooking appliance and its connector will be safely installed by preventing inadequacies in the building fuel gas piping supplying the commercial cooking appliance. Specific safety improvements include: 1. Reducing dangerous strain on improperly installed connectors for Moveable Gas Appliances. 2. Standardized configuration of building gas supply piping in commercial kitchens so that designers, installers, code officials and users have consistent and safe building gas supply arrangements in commercial kitchens. 3. Increases the likelihood that the connector manufacturer s installation and use instructions will be followed, due to safety implications. This additional language increases safety by reducing the risk of fugitive gas resulting from improperly used connectors, potential fires and subsequent losses in commercial kitchens. Similar language is being proposed to the Uniform Mechanical Code, National Fuel Gas Code and other model codes. 188

35 Item #: 172 UPC ( ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: Support of Chimneys. All portions of chimneys shall be supported for the design and weight of the materials employed. Listed factory-built chimneys shall be supported and spaced in accordance with their listings and the manufacturers' instructions. [NFPA 54: ] SUBSTANTIATION: The paragraph is extracted from NFPA 54, and the citation was not included in the 2006 UPC. 189

36 Item #: 173 UPC ( ): SUBMITTER: Douglas Kirk PHCC of California RECOMMENDATION: Revise text as follows: Where the gas appliances to be installed have not been definitely specified, Table 12 1 may be used as a reference to estimate requirements of typical appliances. To obtain the cubic feet per hour (L/sec.) of gas required, divide input of appliances by the average Btu (Watthour) heating value per cubic foot (L) of the gas. The average Btu (Watt-hour) per cubic foot (L) of gas in the area of the installation may be obtained from the serving gas supplier as follows: (1) The serving gas supplier or; (2) Refer to recent gas bill from the serving gas supplier in the area of installation. Locate the therm multiplier and multiply by The sum equals the average Btu (Watt-hour) heating value per cubic foot (L) of the gas supplied. SUBSTANTIATION: The proposed text provides additional information in order to obtain the BTU per cubic feet of gas supplied. Current text indicates that this information may be obtained by the serving gas supplier. However, when contacted, they were unable to obtain this information. 190

37 Item #: 174 UPC ( ): SUBMITTER: Robert Torbin Cutting Edge Solutions LLC RECOMMENDATION: Revise text as follows: For conditions other than those covered by Section , such as longer runs or greater gas demands, the size of each gas piping system shall be determined by standard engineering methods acceptable to the Authority Having Jurisdiction, and each such system shall be so designed that the total pressure drop between the meter or other point of supply and any outlet when full demand is being supplied to all outlets, will at no time exceed fivetenths (0.5) inches (12.7 mm) water column pressure shall comply with the requirements of Section SUBSTANTIATION: The proposed change will make the selection of the maximum pressure drop consistent within the code and with the National Fuel Gas Code. Currently, there is a conflict within the code between Section and Section and Section regarding allowable pressure drop. 191

38 Item #: 175 UPC (Chapter 12 ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: (Revise all extracts from NFPA 54 in Chapter 12 to the 2009 edition of NFPA 54). SUBSTANTIATION: To update the extracted sections of the UPC to the latest edition of NFPA

39 Item #: 176 UPC (1304.0, ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: Psychiatric Patient Rooms. Piping and drain traps in psychiatric patient rooms shall be concealed. Fixtures and fittings shall be resistant to vandalism. [NFPA 101] Locations for Ice Storage. Ice makers or ice storage containers shall be located in nursing stations or similarly supervised areas to minimize potential contamination. [See NFPA 101] SUBSTANTIATION: Delete reference to NFPA 101 in Sections and The subjects are not covered in NFPA 101, Life Safety Code. This proposal is not original material; its reference/source is as follows: NFPA 99, Standard for Health Care Facilities 193

40 Item #: 177 UPC (1309.1, ): SUBMITTER: Krista Braaksma Washington State Building Code Council RECOMMENDATION: Revise text as follows: Part II Medical Gas and Vacuum Systems Application The provisions herein shall apply to the design installation, testing, and verification of medical gas and, vacuum piping systems, and related permanent equipment in hospitals, clinics, and other health care facilities The purpose of this chapter is to provide requirements for the design, installation, testing, and verification of medical gas and, medical vacuum systems, and related permanent equipment, from the central supply system to the station outlets or inlets. SUBSTANTIATION: This proposal provides for more consistency between the two sections and makes the scope more comprehensive. This clarifies the chapter is applicable to other associated equipment used. This proposal is not original material; its reference/source is as follows: This is an existing Washington State Uniform Plumbing Code Amendment developed through our Technical Advisory Group. 194

41 Item #: 178 UPC ( ): SUBMITTER: Theodore C. Lemoff NFPA International RECOMMENDATION: Revise text as follows: Station Outlet An inlet point in a piped medical/surgical vacuum distribution system at which the user makes connections and disconnections. [NFPA ] SUBSTANTIATION: A reference to NFPA 99 is updated. 195

42 Item #: 179 UPC ( ): SUBMITTER: Joseph Kerze Gilbert, AZ RECOMMENDATION: Revise text as follows: Burred ends of all tubing shall be rolled smooth with a chipless reamer or deburred using a deburring tool to the full bore of the tube, and all chips shall be removed. SUBSTANTIATION: Issues and concerns regarding the cut ends of tubing include the following: (1) All references to reaming in the current and past codes states or implies that the burr has to be cut out by removing material therefore forbidding new technologies or innovation in dealing with the problem of de-burring copper pipe that does not remove material. (2) Governing plumbing authorities not familiar with newer technologies for preparing the end of copper pipe for assembly may reject (and have rejected) the use of a tool that does not cut or remove the burr (traditional and stated process) [NFPA ] and UPC 2006 IS but re-forms or smoothes the burr to the full inside diameter of the pipe without removing material. (3) When a burr is removed from a copper pipe by cutting it with a blade type reamer, sharp chips and debris (down to the microscopic level) are created. The chips may become lodged in valves or other devises causing problems or if ingested or inhaled by the end user a health hazard may occur. A chipless reamer reforms the burr without removing material therefore debris is not produced in the process. This may be useful in addressing UPC and NFPA (field contamination of pipe). (4) A sharp clean deburring tool used to ream the tube has sharp surfaces that have the potential to cut or injure the installer particularly if the plumber is in a hurry. A chipless reamer has no sharp edges and prepares the copper pipe in less time than the tools mentioned in the current code therefore decreasing the chance of injury and saving time in the process. (5) When reaming installed hard drawn in the vertical position with a blade reamer most of the chips and debris cut from the pipe falls down the tubing contaminating the system. A chipless reamer does not produce debris in the process of meeting the installation standard of. [NFPA ] (See image on page 196 1) 196

47 Item #: 183 UPC ( ): SUBMITTER: Joseph Kerze Gilbert, AZ RECOMMENDATION: Revise text as follows: Tube ends shall be cut square using a sharp tubing cutter to avoid deforming the tube. [NFPA ] The cutting wheels on tubing cutters shall be free from grease, oil, or other lubricant not suitable for oxygen service. [NFPA ] The cut ends of the tube shall be rolled smooth with a chipless reamer to the full diameter of the tube or deburred with a sharp, clean deburring tool, taking care to prevent chips from entering the tube. [NFPA ] SUBSTANTIATION: Issues and concerns regarding the cut ends of tubing include the following: (1) All references to reaming in the current and past codes states or implies that the burr has to be cut out by removing material therefore forbidding new technologies or innovation in dealing with the problem of de-burring copper pipe that does not remove material. (2) Governing plumbing authorities not familiar with newer technologies for preparing the end of copper pipe for assembly may reject (and have rejected) the use of a tool that does not cut or remove the burr (traditional and stated process) [NFPA ] and UPC 2006 IS but re-forms or smoothes the burr to the full inside diameter of the pipe without removing material. (3) When a burr is removed from a copper pipe by cutting it with a blade type reamer, sharp chips and debris (down to the microscopic level) are created. The chips may become lodged in valves or other devises causing problems or if ingested or inhaled by the end user a health hazard may occur. A chipless reamer reforms the burr without removing material therefore debris is not produced in the process. This may be useful in addressing UPC and NFPA (field contamination of pipe) (4) A sharp clean deburring tool used to ream the tube has sharp surfaces that have the potential to cut or injure the installer particularly if the plumber is in a hurry. A chipless reamer has no sharp edges and prepares the copper pipe in less time than the tools mentioned in the current code therefore decreasing the chance of injury and saving time in the process. (5) When reaming installed hard drawn in the vertical position with a blade reamer most of the chips and debris cut from the pipe falls down the tubing contaminating the system. A chipless reamer does not produce debris in the process of meeting the installation standard of [NFPA ] (See image on page 200 1) 200

Standard Number Standard Title Application ASSE Stack Air Adminttance Valves DWV Components For Sanitary Drainage Systems ASSE Individual and Branch Type DWV Components Air Admittance Valves for Sanitary Drainage Systems SUBSTANTIATION: In plumbing installations it has been necessary to extend vent pipes to the atmosphere. This has resulted in problems relating to extensive vent piping, roof penetrations requiring vent pipe flashings that eventually leak, floor penetrations requiring fire-stopping devices, weakening of building frames, and frost closures as well as pollution of the environment and indoor air by sewer gas. Air admittance valves (AAVs) can resolve problems since they permit a relatively easier solution than venting to the atmosphere. Since there are less open pipes, the possibility of water entering the building through vent pipe roof flashings is substantially reduced. The AAV opens under negative pressure conditions allowing air to enter the DWV system preventing siphonage of the water trap. The valve closes by gravity under neutral and positive pressure, preventing the escape of sewer gas. It operates by means of a pressure/gravity-activated sealing assembly that acts as a one-way valve. Positive pressure will find relief through the open pipe relief vent required on the building drain when AAVs are installed. Systems in which AAVs are installed in conjunction with a minimum of one open vent pipe protect fixture traps against siphonage and backpressure, and air circulation is ensured throughout all parts of the system in compliance with the intent of Section of the UPC. Studies have proven that by installing AAVs in the DWV system both positive and negative pressure transients are reduced and better controlled than in an open pipe system. Installation of AAVs has no adverse effect on the operation of the system and provides benefits in terms of trap seal protection under all conditions. AAVs have been installed in Europe since 1972 and in the USA since The valves have been field tested and have proven to be a safe alternative to open pipe vents. The performance standards for AAVs are ASSE 1050 and 1051 and NSF

189 Item #: 217 UPC ( ): SUBMITTER: Michael Cudahy Plastic Pipe and Fitting Association (PPFA) RECOMMENDATION: Revise text as follows: Valves and Piping. (See Figures 16 1, 16 2, 16 3, and 16 4.) Gray water piping discharging into the holding tank or having a direct connection to the sanitary drain or sewer piping shall be downstream of an approved water seal type trap(s). If no such trap(s) exists, an approved vented running trap shall be installed upstream of the connection to protect the building from any possible waste or sewer gases. All gray water piping shall be marked purple (Pantone color #512) in color and shall be imprinted or have a continuous purple (Pantone color #512) color tape or banding marked with black uppercase lettering, with the words CAUTION: NONPOTABLE WATER, DO NOT DRINK. The minimum size of the letters and length of the color field shall conform to Table 6 1. Where used, a colored identification band shall be indicated every twenty (20) feet (6096 mm), not less than once per room, and shall be visible from the floor level. with the words DANGER UNSAFE WATER. All valves, including the three-way valve, shall be readily accessible and approved by the Authority Having Jurisdiction. A backwater valve installed pursuant to this code shall be provided on all holding tank drain connections to the sanitary drain or sewer piping. SUBSTANTIATION: This section applies to gray water systems for subsurface irrigation. This edit brings the code closer to the marking requirements in other parts of the code. 237

190 Item #: 218 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/REP Water Saver Technologies RECOMMENDATION: Revise text as follows: Reclaimed Water Systems General. (A) The provisions of Part II of this chapter shall apply to the installation, construction, alteration, and repair of reclaimed water systems intended to supply water closets, and urinals, and trap primers for floor drains and floor sinks. Use is limited to these fixtures. that are located in nonresidential buildings. Fixtures within residential buildings are excluded from the list of approved uses. The reclaimed water system shall have no connection to any potable water system, with or without mechanical backflow prevention devices. If reclaimed water is utilized on the premises, all potable water supplies shall be provided with appropriate backflow protection, as required by the Authority Having Jurisdiction. Except as otherwise provided for in this appendix, the provisions of this code shall be applicable to reclaimed water system installations. SUBSTANTIATION: In LEEDs buildings, reclaimed water is used for flushing water closets and urinals in residential buildings. When properly installed, there is no problem with the use of reclaimed water in any building. There is no need to mention the use of reclaimed water for priming traps since this is already permitted with waste type trap seal primers. Apparently, this text preceded the inclusion of this standard in the UPC The last two sentence of this section are left over from when these requirements appeared in the appendix. When they were moved into the body of the code, the statements are no longer necessary. The backflow protection requirements always apply. The other sentence refers to this appendix. 238

191 Item #: 219 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Revise text as follows: Definitions. Reclaimed Water Wastewater and/or storm water that is treated so that is water that, as a result of tertiary treatment of domestic wastewater by a public agency, is suitable for a direct beneficial use or a controlled use that would not otherwise occur. The level of treatment and quality of the reclaimed water shall be approved by the public health Authority Having Jurisdiction. For the purpose of this chapter, tertiary treatment shall result in water that is adequately oxidized, clarified, coagulated, filtered, and disinfected so that at some location in the treatment process, the seven (7) day median number of total coliform bacteria in daily samples does not exceed two and two-tenths (2.2) per one hundred (100) milliliters, and the number of total coliform bacteria does not exceed twenty-three (23) per one hundred (100) milliliters in any sample, and. The water shall be filtered so that the daily average turbidity does not exceed two (2) turbidity units upstream from the disinfection process. Specifically excluded from this definition is gray water, which is defined in Part I of this chapter. SUBSTANTIATION: A definition should not include mandatory requirements. There should only be a definition of a term similar to the definitions that appear in Chapter 2. Reclaimed water has taken on a broader meaning with the use in green building design. Storm water and gray water are used as reclaimed water for flushing fixtures. If the water meets the quality requirements, it can be used for flushing fixtures. 239

192 Item #: 220 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Revise text as follows: Pipe Material/Pipe Identification. Reclaimed water piping pipe, valves and fittings shall be as required in this code for potable water piping and fittings conform to the requirements of Sections 604.0, and All reclaimed water pipe and fittings shall be identified in accordance with Section continuously wrapped with purple-colored Mylar tape. The wrapping tape shall have a minimum nominal thickness of five ten-thousandths (0.0005) inch (0.127 mm) and a minimum width of two (2) inches (51 mm). Tape shall be fabricated of poly(vinyl chloride) with a synthetic rubber adhesive and a clear polypropylene protective coating or approved equal. The tape shall be purple (Pantone color #512) and shall be imprinted in nominal onehalf (1/2) inch (12.7 mm) high, black uppercase letters, with the words CAUTION: RECLAIMED WATER, DO NOT DRINK. The lettering shall be imprinted in two (2) parallel lines, such that after wrapping the pipe with a one-half (1/2) inch width overlap, one (1) full line of text shall be visible. Wrapping tape is not required for buried PVC pipe manufactured with purple color integral to the plastic and marked on opposite sides to read CAUTION: RECLAIMED WATER, DO NOT DRINK in intervals not to exceed three (3) feet (914 mm). All valves, except fixture supply control valves shall be equipped with a locking feature. All mechanical equipment that is appurtenant to the reclaimed water system shall be painted purple to match the Mylar wrapping tape. SUBSTANTIATION: Section has specific requirements for labeling all non-potable water systems. This section is in conflict with Section It is more appropriate to use the specific labeling requirements of Section If this section remains in the code, reclaimed water piping systems would have to be dual marked, one in accordance with this section, the other in accordance with Section

193 Item #: 221 UPC ( ): SUBMITTER: Michael Cudahy Plastic Pipe and Fitting Association (PPFA) RECOMMENDATION: Revise text as follows: Pipe Material/Pipe Identification. Reclaimed water piping and fittings shall be as required in this code for potable water piping and fittings. All reclaimed water pipe and fittings shall be continuously wrapped with purple-colored Mylar PVC, polypropylene or approved equivalent tape. The wrapping tape shall have a minimum nominal thickness of five ten-thousandths (0.0005) inch (0.127 mm) and a minimum width of two (2) inches (51 mm). Tape shall be fabricated of poly(vinyl chloride) with a synthetic rubber adhesive and a clear polypropylene protective coating or approved equal. The tape shall be purple (Pantone color #512) and shall be imprinted in nominal onehalf (1/2) inch (12.7 mm) high, black uppercase letters, with the words CAUTION: RECLAIMED WATER, DO NOT DRINK. The lettering shall be imprinted in two (2) parallel lines, such that after wrapping the pipe with a one-half (1/2) inch width overlap, one (1) full line of text shall be visible. Wrapping tape is not required for buried PVC concealed plastic or composite pipe manufactured with purple color integral to the plastic pipe and marked on opposite sides to read CAUTION: RECLAIMED WATER, DO NOT DRINK in intervals not to exceed three (3) five (5) feet (914 mm) (1524 mm.) All valves, except fixture supply control valves shall be equipped with a locking feature. All mechanical equipment that is appurtenant to the reclaimed water system shall be painted purple to match the Mylar wrapping tape or plastic pipe color. SUBSTANTIATION: This section of the code applies to reclaimed water, or water that is municipally treated to a level suitable for human contact, but not drinking. There is also a conflict here as wrapping (marking) tape cannot be Mylar (polyester), PVC and polypropylene. Other plastic pipes than PVC can be colored purple, including composite piping, and in the future, use of purple pipes will become more common in these systems. 241

194 Item #: 222 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Revise text as follows: Installation. (A) Hose bibbs shall not be allowed on reclaimed water piping systems. (B) The reclaimed water system and the potable water system within the building shall be provided with the required appurtenances (valves, air/vacuum relief valves, etc.) to allow for deactivation or drainage as may be required by this chapter. (CB) Reclaimed water pipes shall not be run or laid in the same trench as potable water pipes. A ten (10) foot (3,048 mm) horizontal separation shall be maintained between pressurized, buried reclaimed and potable water piping. Buried potable water pipes crossing pressurized reclaimed water pipes shall be laid a minimum of twelve (12) inches (305 mm) above the reclaimed water pipes. Reclaimed water pipes laid in the same trench or crossing building sewer or drainage piping shall be installed in compliance with Sections and of this code. Reclaimed water pipes shall be protected similar to potable water pipes. SUBSTANTIATION: The paragraph proposed for deletion makes no sense when the former appendix was placed in the body of the code. There are no requirements listed, nor is there a requirement for drainage listed. This section can be deleted without any impact to the overall use of the reclaimed water section. 242

195 Item #: 223 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Revise text as follows Signs. (A) Room Building Entrance Signs. All installations using reclaimed water for water closets and/or urinals shall be identified with signs. Each sign shall contain one half (1/2) inch (12.7 mm) letters of a highly visible color on a contrasting background. The location of the sign(s) shall be such that the sign(s) shall be visible to all users. The number and location of the signs shall be approved by the Authority Having Jurisdiction and shall contain the following text: TO CONSERVE WATER, THIS BUILDING USES RECLAIMED WATER TO FLUSH TOILETS WATER CLOSETS AND URINALS. (B) Equipment Room Signs. Each equipment room containing reclaimed water equipment shall have a sign posted with the following wording in one (1) inch (25.4 mm) letters on a purple background: CAUTION RECLAIMED WATER, DO NOT DRINK. DO NOT CONNECT TO DRINKING WATER SYSTEM. NOTICE CONTACT BUILDING MANAGEMENT BEFORE PERFORMING ANY WORK ON THIS WATER SYSTEM. This sign shall be posted in a location that is visible to anyone working on or near reclaimed water equipment. (C) Where tank-type water closets are flushed with reclaimed water, the tank shall be labeled: RECLAIMED WATER DO NOT DRINK (D) Valve Access Door Signs. Each reclaimed water valve within a wall shall have its access door into the wall equipped with a warning sign approximately six (6) inches by six (6) inches (152 mm x 152 mm) with wording in one half (1/2) inch (12.7 mm) letters on a purple background. The size, shape, and format of the sign shall be substantially the same as that specified in subsection (B) above. The signs shall be attached inside the access door frame and shall hang in the center of the access door frame. This sign requirement shall be applicable to any and all access doors, hatches, etc., leading to reclaimed water piping and appurtenances. (E) Valve Seals. Each valve or appurtenance shall be sealed in a manner approved by the Authority Having Jurisdiction after the reclaimed system has been approved and placed into operation. These seals shall either be a crimped lead wire seal or a plastic breakaway seal which, if broken after system approval, shall be deemed conclusive evidence that the reclaimed water system has been accessed. The seals shall be purple with the words RECLAIMED WATER and shall be supplied by the reclaimed water purveyor or by other arrangements acceptable to the Authority Having Jurisdiction. SUBSTANTIATION: The signs indicating that the building uses reclaimed water are at the entrance to the building. The designation room is misleading. It is better to use Building. The fixtures are water closets, hence, the flushing should indicate water closets, not toilets. Not all equipment is located in equipment rooms. The deletion of equipment will help to clarify that any room having equipment for reclaimed water must be labeled. The sealing of meters or valves is a jurisdictional requirement that does not belong in the code. Not all reclaimed water is supplied by public authorities. This section is left over from when this appeared as a stand alone appendix. 243

196 Item #: 224 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Revise text as follows: Inspection and Testing. (A) Reclaimed water piping shall be tested as outlined in this code for testing of potable water piping. (B) An initial and subsequent annual crossconnection inspection and test shall be performed on both the potable and reclaimed water systems as follows. (1) Visual Dual System Inspection. Prior to commencing the cross-connection testing, a dual system inspection shall be conducted by the Authority Having Jurisdiction and other authorities having jurisdiction. (i) Meter locations of the reclaimed water and potable water lines shall be checked to verify that no modifications were made, and that no cross-connections are visible. (ii) All pumps and equipment, equipment room signs, and exposed piping in equipment room shall be checked. (iii) All valves shall be checked to ensure that valve lock seals are still in place and intact. All valve control door signs shall be checked to verify that no signs have been removed. (2) Cross-Connection Test. The following procedure shall be followed by the applicant in the presence of the Authority Having Jurisdiction and other authorities having jurisdiction to determine whether a crossconnection occurred. (i) The potable water system shall be activated and pressurized. The reclaimed water system shall be shut down and completely drained. (ii) The potable water system shall remain pressurized for a minimum period of time specified by the Authority Having Jurisdiction while the reclaimed water system is empty. The minimum period the reclaimed water system is to remain depressurized shall be determined on a case-by-case basis, taking into account the size and complexity of the potable and reclaimed water distribution systems, but in no case shall that period be less than one (1) hour. (iii) All fixtures, potable and reclaimed, shall be tested and inspected for flow. Flow from any reclaimed water system outlet shall indicate a cross-connection. No flow from a potable water outlet would indicate that it may be connected to the reclaimed water system. (iv) The drain on the reclaimed water system shall be checked for flow during the test and at the end of the period. (v) The potable water system shall then be completely drained. (vi) The reclaimed water system shall then be activated and pressurized. (vii)the reclaimed water system shall remain pressurized for a minimum period of time specified by the Authority Having Jurisdiction while the potable water system is empty. The minimum period the potable water system is to remain depressurized shall be determined on a case-bycase basis, but in no case shall that period be less than one (1) hour. (viii) All fixtures, potable and reclaimed, shall be tested and inspected for flow. Flow from any potable water system outlet shall indicate a cross-connection. No flow from a reclaimed water outlet would indicate that it may be connected to the potable water system. (ix) The drain on the potable water system shall be checked for flow during the test and at the end of the period. (x) If there is no flow detected in any of the fixtures which would have indicated a cross connection, the potable water system shall be repressurized. (3) In the event that a cross-connection is discovered, the following procedure, in the presence of the Authority Having Jurisdiction, shall be activated immediately: 244

197 (i) Reclaimed water piping to the building shall be shut down at the meter, and the reclaimed water riser shall be drained. (ii) Potable water piping to the building shall be shut down at the meter. (iii) The cross-connection shall be uncovered and disconnected. (iv) The building shall be retested following procedures listed in subsections (B)(1) and (B)(2) above. (v) The potable water system shall be chlorinated with fifty (50) ppm chlorine for twenty-four (24) hours. (vi) The potable water system shall be flushed after twenty-four (24) hours, and a standard bacteriological test shall be performed. If test results are acceptable, the potable water system may be recharged. (C) An annual inspection of the reclaimed water system, following the procedures listed in subsection J 8 (B)(1), shall be required. Annual cross-connection testing, following the procedures listed in subsection J 8 (B)(2), shall be required by the Authority Having Jurisdiction, unless site conditions do not require it. In no event shall the test occur less often than once in four (4) years. Alternate testing requirements may be allowed by the Authority Having Jurisdiction for institutional buildings. The health officer or other designated appointee may substitute for the Authority Having Jurisdiction in the above- mentioned inspections and tests. SUBSTANTIATION: These section were necessary when the reclaimed water requirements were a stand alone appendix. When the text was moved to the body of the code, the requirements are already addressed by other section of the code. Cross-connection control is adequately covered in Section 603. The inspection requirements are covered in Chapter 1. ASSE Series 5000 is listed in Chapter 14 for the procedures to follow for annual testing of backflow preventers 245

198 Item #: 225 UPC ( ): SUBMITTER: Julius Ballanco JB Engineering and Code Consulting PC/Rep. Water Saver Technologies RECOMMENDATION: Delete text without substitution: Approved Uses of Reclaimed Water. Reclaimed water is allowed in all non-residential buildings to supply fixtures as specified in this chapter, except where prohibited by statute, regulation, or ordinance. SUBSTANTIATION: Section addresses where reclaimed water can be used in a building. There is no need to duplicate the requirements at the end of the chapter. 246

199 Item #: 226 UPC (Appendix A, A-2 ): SUBMITTER: Bob Adler Chair, Correlation Task Group RECOMMENDATION: The following is a recommendation from the Correlation Task Group. Revise text as follows: Table A-2 Water Supply Fixture Units (WSFU) and Minimum Fixture Branch Pipe Sizes 3 Shower per head; Urinal 1.0 GPF Flushometer Valve; Urinal greater than 1.0 GPF Flushometer Valve. SUBSTANTIATION: These entries were inadvertently left out of Table A-2 and should correlate with Table

200 Item #: 227 UPC (Appendix A, A 3.3 ): SUBMITTER: Dave Kokosenski RCR Companies RECOMMENDATION: Add new text as follows: Appendix A A 3.3 Whenever a water filter, water softener, or similar water treating device, backflow prevention device, tankless water heater, or similar device is installed in any water supply line, the pressure loss through such devices shall be included in the pressure loss calculations of the system. The water supply pipe and meter shall be adequately sized to provide for any such pressure loss. No water filter, water softener, backflow prevention device, or similar device regulated by this Code shall be installed in any potable water supply piping when the installation of such device produces an excessive pressure drop in any such water supply piping. In the absence of specific pressure drop information, the diameter of the inlet or outlet of any such device or its connecting piping shall not be less than the diameter of such water distribution piping to the fixtures served by the device. All such devices shall be of a type approved by the Authority Having Jurisdiction and shall be tested for flow rating and pressure loss by an approved laboratory or recognized testing agency to standards consistent with the intent of this Appendix. (Renumber remaining sections) SUBSTANTIATION: The current code does not require us to include tankless water heaters in the pressure loss calculations of a system. These tankless water heaters do in fact produce a greater pressure drop when compared to a water meter, pressure reducing valve, filter, softener, backflow device, or elevation. By adding this section the losses through a tankless water heater would be accounted for and velocities of 5 feet per second would not be exceeded. When sizing these heaters, typically they are only flowing 2 shower heads. When sizing our piping we must account for all losses within the system. When I requested an IAPMO interpretation regarding this, the response was the losses must be included and was covered with the words other similar devices, which could be misinterpreted. By adding these words it would be clear. Sections , and Installation Standard 3, Section of the 2001 California Plumbing Code limit the velocities in copper hot water piping to 5 feet per second. The Copper Development Association's, "The Copper Tube Handbook", also limits the velocities in copper hot water piping to 5 feet per second. The 2003 Illustrated Training Manual mentions 4 feet per second on hot. These velocities will be exceeded when installing a single tankless water heater. See the attached below.

207 Item #: 232 UPC (TIA UPC , Appendix K, Sections K1(A), K1(D), K5(K), Table K-1): SUBMITTER: John Ingargiola FEMA Mitigation RECOMMENDATION: Revise text as follows: K 1 Private Sewage Disposal General (A) Where permitted by Section the building sewer may be connected to a private sewage disposal system complying with the provisions of this appendix. The type of system shall be determined on the basis of location, soil porosity, and groundwater level, and shall be designed to receive all sewage from the property. The system, except as otherwise approved, shall consist of a septic tank with effluent discharging into a subsurface disposal field, into one (1) or more seepage pits, or into a combination of subsurface disposal field and seepage pits. The Authority Having Jurisdiction may grant exceptions to the provisions of this appendix for permitted structures which have been destroyed due to fire or natural disaster and that cannot be reconstructed in compliance with these provisions provided that such exceptions are the minimum necessary. (D) Disposal systems shall be located outside of flood hazard areas. Exception: Where suitable sites outside of flood hazard areas are not available, disposal systems may be located in flood hazard areas on sites where the effects of inundation under conditions of the design flood are minimized. Re-letter existing K1(D) and subsequent subsections. K 5 Septic Tank Construction (K) Structural Design. (1) General. Each such tank shall be structurally designed to withstand all anticipated earth or other loads. All septic tank covers shall be capable of supporting and earth load of not less than three hundred (300) pounds per square foot (14.4 kpa) when the maximum coverage does not exceed three (3) feet (914 mm). (2) Flood Loads. In flood hazard areas, tanks shall be anchored to counter buoyant forces during conditions of the design flood. The vent termination and service manhole of the tank shall be a minimum of 2 feet (610 mm) above the design flood elevation or fitted with covers designed to prevent the inflow of floodwater or outflow of the contents of the tanks during conditions of the design flood. Table K-1 Location of Sewage Disposal Systems (See attached, Page 254 1) Note: 7. These minimum clear horizontal distances shall also apply between disposal fields, seepage pits, and the ocean mean higher high-tide line. SUBSTANTIATION: Technical Nature: These code changes result in consistency with the National Flood Insurance Program provisions relating to new and replacement onsite waste disposal systems, as set forth in federal regulations at 44 CFR 60.3(a)(6). The NFIP regulations require that sanitary sewage systems be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into floodwaters and that onsite waste disposal systems be located to avoid impairment to them or contamination from them during flooding. The most effective way to achieve this is to site systems outside of flood hazard areas if practicable, or at locations where the impacts of flooding are minimized, generally on higher ground. With respect to location of sewage disposal systems, the term streams may not be sufficiently inclusive to capture other names for bodies of water such as creeks, runs, bayous, sloughs, rivers, and the like. In addition, in floodplain management, the most common reference in coastal areas is the mean high tide (although many states and communities have adopted coastal setback lines that apply to installation of sewage disposal systems and buildings. Emergency Nature: Local jurisdictions that have been identified as subject to flooding as indicated on maps prepared for the National 253

208 Flood Insurance Program (NFIP) are required to regulate development in flood hazard areas in order to qualify for certain forms of federal disaster assistance and for their citizens to be able to purchase federal flood insurance. To protect citizens and their property, it is important that the codes that govern construction include provisions to minimize damage and exposure to flooding. In addition, many local jurisdictions participate in the NFIP s Community Rating System (CRS). The CRS offers discounts on federal flood insurance premiums in communities that administer floodplain management programs that exceed the NFIP minimum requirements. The U.S. Department of Homeland Security/FEMA has determined that the proposed changes to the UPC will result in consistency with the NFIP regulations. Because of the multi-hazard benefits that accrue from administration of building codes, especially codes that include flood-resistant provisions, communities that adopt the UPC and other NFIP-consistent codes will qualify for additional points under the CRS. (Below are the comments of the Council) The proposed TIA was balloted through the Plumbing Technical Committee in accordance with the Regulations Governing Committee Projects to determine if there existed the necessary three-fourths majority support on technical merit and emergency nature to establish the recommendation for issuance. The letter ballot passed with only one negative vote on both accounts. In determining whether or not to issue a TIA, the Council looks to the TC letter ballot for a recommendation of support, and in this case, that support exists. The Council notes the Technical Committee s concurrence with the substantiation provided proponent on the issues of emergency nature and technical merit and concurs with said substantiation. The Council also notes the public comment submitted by RC Quinn Consulting Inc. dated September 23, 2005 in support of the proposed TIA and public comment heard in support of the proposed TIA during the public hearing. Upon a full review and consideration of all the information available to it, the Council voted to accept the recommendation of the Technical Committee and issue proposed TIA UPC In accordance with section 5 8 of the Regulations Governing Committee Projects, this TIA shall also apply to the 2006 edition of the Uniform Plumbing Code. 254

210 Item #: 233 UPC (Appendix L, L-1, L-2, L 4.0 ): SUBMITTER: Bob Adler Chair, Correlation Task Group RECOMMENDATION: Revise text as follows: The following are the recommendation of the Correlation Task Group (see Correlation Task Group Report Item #233) Appendix L TABLE L-1 Water Supply Fixture Units (WSFU) for Private or Private Use 1, 2 Bathroom Groups Serving 3 or more Individual Dwelling Units Dwelling Units Private Use Private Use Bathroom Group Bathroom Group Appendix L Table L-2 Drainage Fixture Unit Values (DFU) for Private or Private Use Bathroom Groups Serving 3 or more Individual Dwelling Units Dwelling Units Private Use Private Use Bathroom Group Bathroom Group L 4.0 Fixture Unit Values for Private or Private Use Bathroom Groups. SUBSTANTIATION: In various sections throughout the code the terms dwelling units, multi-dwelling units, single-family dwelling units, single dwelling units, individual dwelling units and three or more dwelling units are used for specific applications. The code does not define any of these terms and the application on some of these sections applies to plumbing fixtures. In order to determine the application based on plumbing fixtures these terms should be reviewed for relevance and replaced with either public or private use where reference is made to plumbing fixtures. The suggested revision is to correlate the requirements based on public and private use. The code defines private or public as it applies to plumbing fixtures for the types of fixtures required in those occupancies. Current text contains language that is not defined in the UPC such as dwelling unit and public building. 255

211 Item #: 234 UPC (Appendix L, L-1 ): SUBMITTER: Gary Klein California Energy Commission RECOMMENDATION: Revise text as follows: Section L 4.2 The listed water supply fixture unit values in Table L-1 reflect the load of entire bathroom groups of the hot and cold water distribution systems on the cold-water service. Individual hot and cold water branch piping to the fixtures should be sized according to Chapter 6 and Appendix A. The sizes indicated in Chapter 6 and Appendix A shall be used unless approved engineering calculations indicate that a smaller diameter is acceptable or that a larger diameter is required. TABLE L-1 Water Supply Fixture Units (WSFU) for Bathroom Groups 1,2 Individual Dwelling Units Serving 3 or more Dwelling Units COLD HOT 3 COLD HOT Bathroom Groups Having up to 1.6 GPF Gravity-Tank Water Closets Half-bath or Power Room Bathroom Group /2 Bathrooms Bathrooms /2 Bathrooms Bathrooms Each Additional ½ Bath Each Additional Bathroom Group Bathroom Groups Having up to 1.6 GPF Pressure-Tank Water Closets Half-bath or Power Room Bathroom Group /2 Bathrooms Bathrooms /2 Bathrooms Bathrooms Each Additional ½ Bath Each Additional Bathroom Group Bathroom Groups Having 3.5 GPF Gravity-Tank Water Closets Half-bath or Power Room Bathroom Group /2 Bathrooms Bathrooms /2 Bathrooms Bathrooms 12.0 Each Additional ½ Bath 0.5 Each Additional Bathroom Group 1.0 Bath Group (1.6 GPF Flushometer Value) Bath Group (3.5 GPF Flushometer Value) Kitchen Group (Sink and Dishwasher) Laundry Group (Sink and Clothes Washer) Notes: 1. A bathroom group, for the purposes of this table, consists of one water closet, up to two lavatories, and either one bathtub or one shower. 2. A half-bath or powder room, for the purposes of this table, consists of one water closet and one lavatory. 3. Multi-Unit dwellings with individual water heaters use the same WFSU as for individual dwellings. 256

212 SUBSTANTIATION: The purpose of this proposal is to revise the Water Supply Fixture Units (WSFU) for Bathroom Groups, Individual Dwelling Units (Table L-1) to separate hot and cold water in the same way that we proposed revisions to Table 6-4 and for the same reasons. As in Chapters 2 and 6, the proposal in this appendix distinguishes between hot and cold potable water and stipulates that the pipe sizes listed in Chapter 6 and Appendix A are to be used unless engineering calculations indicate that a smaller diameter is acceptable or that a larger diameter is required. In addition, Table L-1 has been revised so that hot water has the same relative diversity factor for hot water consuming fixtures as cold water does for cold water consuming fixtures. It also reflects the reduction in WSFUs to ¾ for combined hot and cold water fixtures as reflected in Table 6 5 and Table A-2. The California Energy Commission, its supporting research organizations and other collaborators have been investigating the impact of the hot water distribution system s design on the overall energy and water performance of a building s hot water system. While our research and investigations are likely to lead to modifications in the Building Energy Efficiency Standards portion of California s Building Standards Code (Title 24), a number of potential ways to enhance the performance of these systems is influenced or governed by the requirements of plumbing codes including the Uniform Plumbing Code (UPC). Based on our research, the key factor in determining the performance of hot water distribution systems is to design and build them to have the smallest volume of water within that portion of the system between the plumbing fixture and the source of hot water. The length and the internal diameter of the pipe(s) determine the volume of water contained within the distribution system. Systems with the least internal volume waste the least amount of energy and water. They also typically provide hot water to the plumbing fixture with the shortest waiting period typically the most important consideration to the hot water user. Unfortunately, the current plumbing codes do not differentiate between hot and cold water piping in the design and installation of a distribution system. Without this differentiation, current hot water distribution systems typically become over-sized while following the guidance provided by plumbing codes. Excessive pipe size has little or no negative water or energy conservation impact on cold water systems but it is a big factor in reducing the performance of hot water distribution systems. A review of the UPC identified several areas (listed in our proposals) that could be changed in order to reduce water and energy wasted in hot water distribution as well as the waiting period for hot water to arrive at the fixture. We believe that the changes we have proposed improve energy and water performance while appropriately addressing the hydrodynamic factors of velocity (erosion, noise and water hammer) and friction losses (pressure drop and restrictions due to length and fittings). In addition, since our recommendations decrease the time it takes to get hot water from the source to the fixtures, hot water will be available more quickly when a faucet is opened. This is particularly important in food service and public restrooms, where these changes will support the health code s intent to have hot water readily available at all times during all operating hours. The diversity factors implied in the current Table L-1 for cold and hot water supplies are not equal. For example, for 1 Bathroom Group the WSFUs for all cold water fixtures (from Table 6 4) is 7.5 while the WSFUs for all hot water fixtures is 5.0. Table L-1 (for 1 Bathroom Group) uses 5.0 WSFU for both hot and cold. Thus the diversity factor for cold is 7.5 / 5.0 = 0.66, while for hot it is 5.0 / 5.0 = 1.0. The other diversity factors are as follows: Bathroom Grouping Cold WSFUs Cold Cold Water Hot WSFUs Hot WSFU Hot Water Table 6 5 WSFUs Diversity Table 6 5 (75%) Table L-1 Diversity Table L-1 Factor Factor Half-bath or Power = Room 1 Bathroom Group = = /2 Bathrooms = = Bathrooms = = / = = Bathrooms 3 Bathrooms = = Each Additional ½ Bath Each Additional

213 Bathroom Group The following table shows compares the relative hot and cold water diversity factors: Bathroom Grouping Cold Water Hot Water Diversity Factor Diversity Factor Half-bath or Power Room Bathroom Group /2 Bathrooms Bathrooms /2 Bathrooms Bathrooms Each Additional ½ Bath Each Additional Bathroom Group As can be seen above, the diversity factor for hot water is at least 50% higher that for cold water which dramatically reduces its impact. Since the diversity factor reflects the probability of concurrent use, it is reasonable and logical that the factor for both hot and cold water be the same for each bathroom group. The proposed revisions to Table L-1 reflect the same diversity factor among both hot and cold water. It also reflects the reduction in WSFUs to ¾ for combined hot and cold water fixtures as reflected in Table 6 5 and Table A-2. We have also proposed that bathroom groups with 3.5 gallons per flush be removed from the table. This is consistent with the changes made to Tables 6 5 and A-2 made during the 2006 code revision cycle and it is consistent with EPAct which limits toilets to 1.6 gallons per flush. 258

L 6.1 Batteries of Fixtures (Battery Venting). L A maximum of eight (8) floor-outlet water closets, showers, bathtubs, or floor drains connected in battery on a horizontal branch drain shall be permitted to be battery-vented. The drain from each fixture being battery-vented shall connect horizontally to the horizontal wet-vented drain branch. The horizontal wet-vented branch drain shall be considered as a vent extending from the downstream fixture drain connection to the most upstream fixture connection. L Back-outlet water closets having carriers conforming to Section shall be permitted to be batteryvented provided they connect horizontally to the horizontal wet-vented section. L Trap arm lengths for fixtures shall not exceed those as indicated in Table L A battery vent shall be connected to the horizontal wet-vented branch drain between the two (2) most upstream fixture drains.

The battery venting section was replaced with a more up to date L7.0 on circuit venting. The bathroom group wet venting provisions were added to Chapter 9. Hence, this section is no longer needed in the code. 262

220 Item #: 237 UPC (TIA UPC Appendix L, L 8.6): SUBMITTER: Nasser Nikravi State of California/Rep. OSHPD RECOMMENDATION: Revise text as follows: L 8.6 Additional venting required. Additional venting shall be provided when more than one water closet is on a horizontal branch and where the distance from a fixture trap to the stack exceeds the limits in Section L8.4. Where additional venting is required, the fixture(s) shall be vented by individual vents, common vents, wet vents, circuit vents, or a combination waste and vent pipe. The dry vent extensions for the additional venting shall connect to a branch vent, vent stack, stack vent, air admittance valve, or be extended outdoors and terminate to the open air. SUBSTANTIATION: Emergency Nature: The UPC Technical Committee did not intend to include Air Admittance Valves in this Section. The committee has consistently declined to approve the use of Air Admittance Valves for all of the reasons previously stated by the committee in the 2004 Report on Proposals and 2005 Report on Comments. Inclusion of the phrase air admittance valve in this Section is an error that was overlooked during the revision process. Technical Basis: In support of this oversight the committee declined to approve the addition of standards ASSE Performance Requirements for Stack Air Admittance Valves for Sanitary Drainage Systems and ASSE Performance Requirements for Individual and Branch Type Air Admittance valves for Sanitary Drainage Systems, to Table Therefore, there is no recognized standard in the UPC for this product. (Comments by the Council are below) Upon a full review and consideration of all of the information available to it including testimony presented at the hearing, the Council concludes that the Plumbing Technical Committee did not intend to include the phrase air admittance valve when it approved comment sequence #088 and therefore the Council votes to issue TIA UPC (Council members Edward Saltzberg, Terry Swisher and Phillip Ribbs recused themselves from voting). The Council agrees with the reasons set forth by the proponent and notes that the Technical Committee has consistently declined to approve the use of air admittance valves. The Council is aware that the 2006 edition of the Uniform Plumbing Code does not contain any standards related to the installation of air admittance valves nor is a definition of air admittance valve contained within the text of the 2006 Uniform Plumbing Code. 263

221 Item #: 238 UPC (Appendix L, L-9.0, L 9.1 and Table L 9.0 (New) ): SUBMITTER: Gary Klein California Energy Commission RECOMMENDATION: Add new text as follows: L 9.0 Pipe Insulation. L 9.1 Where required. Hot water distribution piping shall be completely insulated with at least the amount of insulation specified in Table L 9.0, and installed in accordance with the manufacturer s instructions. Pipe supports shall be installed on the outside of the pipe insulation. For purposes of determining completeness, pipe insulation shall be installed to within ¼ inch of all appliances, appurtenances, fixtures, structural members or a wall where the pipe passes through to connect to a fixture within 24 inches. Exception: Where hot water distribution piping is buried within attic, crawlspace or wall insulation. In attics and crawlspaces the insulation shall cover the pipe at least 4 inches further away from the conditioned space. In walls, the insulation must completely surround the pipe with at least 1 inch of insulation. If burial within the insulation will not completely or continuously surround the pipe, then this exception does not apply. (See attached Table L 9.0 Minimum Wall Thickness of Pipe Insulation on page 264 1) SUBSTANTIATION: (See attached document Substantiation on page through 264 7) 264

223 UPC 2009 (Appendix L, L9.0) Substantiation: The purpose of this proposal is to add the requirement for the insulation of hot water distribution piping. The California Energy Commission, its supporting research organizations and other collaborators have been investigating the impact of the hot water distribution system s design on the overall energy and water performance of a building s hot water system. While our research and investigations are likely to lead to modifications in the Building Energy Efficiency Standards portion of California s Building Standards Code (Title 24), a number of potential ways to enhance the performance of these systems is influenced or governed by the requirements of plumbing codes including the Uniform Plumbing Code (UPC). A review of the UPC identified several areas (listed in our various proposals) that could be changed in order to reduce water and energy wasted in hot water distribution as well as the waiting period for hot water to arrive at the fixture. We believe that the changes we have proposed improve energy and water performance while appropriately addressing the hydrodynamic factors of velocity (erosion, noise and water hammer) and friction losses (pressure drop and restrictions due to length and fittings). In addition, since our recommendations decrease the time it takes to get hot water from the source to the fixtures, hot water will be available more quickly when a faucet is opened. This is particularly important in food service and public restrooms, where these changes will support the health code s intent to have hot water readily available at all times during all operating hours. Based on our research, another important factor in determining the performance of hot water distribution systems (beyond having the smallest volume of water within the system) is to insulate the pipes. From the energy perspective, insulation reduces energy waste during a hot water event. Just as important, insulation is particularly beneficial for those occupancies with consecutive draws on the same line from the source of hot water that are clustered reasonably close together in time, such as food service operations and the morning rush hour and evening plateau patterns found in many households. In these cases, insulation extends the time it takes for the hot water in the pipes to cool down. This increasing the number of hot water events in which hot water will arrive at the plumbing fixture with less waste of water and energy and in less time an important consideration to the hot water user, and to health officials alike. Unfortunately, the current plumbing codes do not require the installation of insulation on a hot water distribution system. Substantiation for Proposal: Hot water events A typical hot water event is depicted in the figure below. Each hot water event has three phases: delivery, use, and cool down. When a fixture valve is opened, hot water leaves the water heater and heads through the hot water piping toward the fixture. Ideally, we want this delivery time to be as short as possible. (See attached image 1 on page 264-6) The Delivery Phase may be short at some fixtures and long at others. It may be short or long at the same fixture depending on when hot water was last needed on the same line serving another fixture elsewhere in the building. The use phase is whatever length it takes to perform the task for which hot water is desired. The cool down phase begins the moment the fixture is turned off. If the time until the next hot water event is short enough, the water in the pipes all the way back to the water heater will be hot enough to use immediately. If it is too long, water coming from the water heater for that next event will be run down the drain until water hot enough to use arrives at the fixture. The Use Phase The next figure compares the performance of nominal ½- and ¾-inch diameter copper piping, both insulated and uninsulated. The graph is based on steady-state flow rates with the hot water entering the pipe at 135 F and the 264-2

224 UPC 2009 (Appendix L, L9.0) ambient air temperature surrounding the pipe at 67.5 F over a length of 100 feet. (See attached image 2 on page 264-6) As shown in the figure above, insulation reduces the heat loss overall. For a given flow rate, insulation causes the temperature drop to be roughly halved. Insulation also reduces the difference in temperature drop between ½- and ¾-inch diameter piping. The Cool-Down Phase We learned that insulation extends the time it takes for the pipes to cool down to a given temperature. The real question is: how long does it take to cool down to a non-useful hot water temperature? This depends upon the starting temperature of the water in the pipes, the diameter of the pipes, the amount of pipe insulation, the environmental conditions in which the pipes are located, and the temperature of water needed for the next hot water event. The figure below compares how long it took for the water in ½-inch diameter copper pipes to cool down from a given starting temperature to 105 F. The ambient temperature surrounding the pipes was between 65 and 70 F and the pipes were located in air. Without insulation, it took between 5 and 20 minutes for the temperature to reach 105 F. Use of the ¾ inch thick insulation (>R-4) roughly doubled the cool down time. The ½-inch wall thickness insulation did almost as well. Time Required for ½-Inch Diameter Pipes to Cool Down to 105 F, With and Without Pipe Insulation (See attached image 3 on page 264-7) Time Required for ¾ -Inch Diameter Pipes to Cool Down to 105 F, With and Without Pipe Insulation (See attached image 4 on page 264-7) Although the time it took the water in the uninsulated pipes to cool down was very similar for the ½-inch and ¾- inch diameter pipes, when insulation was added, the water in the ¾-inch pipes took roughly 1.5 times as long to reach the same temperature as the ½-inch pipes. Insulation is the best way to improve a hot water event during the use and cool down phases. Regardless of whether you have already improved performance by reducing the volume of water in the pipe, reducing the effective pipe length and getting the hot water to the fixture more quickly, pipe insulation will help maintain the temperature during the event and reduce the rate at which the pipes cool down when the fixture is turned off. Delaying the cool down time effectively increases the number of times there are hot starts in the delivery phase. The preceding paragraphs were adapted from an article that appeared in the September/October 2006 issue of the Official Magazine, entitled Hot Water Distribution Research. Please refer to that article for a more complete discussion. Since that article was published, additional empirical research has been completed that shows that uninsulated hot water pipes installed in soil such as found under slab-on-grade construction have significantly larger heat loss than pipes installed in air. While not surprising, these recent findings support the case for insulating all hot water distribution piping. Impact of water use patterns Some people will ask if insulation should be required because it primarily benefits those occupancies where the hot water events on the line from the source of hot water are clustered relatively closely together in time. The difficulty is determining which use pattern (clustered or spread out) will be the primary pattern in a given building 264-3

225 UPC 2009 (Appendix L, L9.0) over the lifetime of the plumbing. For individual dwelling units, the most common hot water use pattern is a morning peak and an afternoon-toevening plateau. This pattern is typical for weekdays of working households and those with children in school. Weekends are different and in general, the pattern is more spread out. The pattern may get more spread out as the household changes over time; the children leave the house and the adults no longer leave for work every day. However, when these occupants leave, something that happens roughly 5-7 years on average, a new group of occupants will move in, and they will have their own hot water use pattern. Food service operations experience peaks during meal times, but many have some level of regular business throughout their hours of operation. At the other extreme are occupancies where the hot water fixtures are used only intermittently, sometimes for only a small portion of the day or only a few times a week. Under a contract with the California Energy Commission, Oak Ridge National Laboratory (ORNL) developed a computer program to simulate the energy, water and time impacts of hot water use patterns in buildings with different hot water distribution systems, or different hot water use patterns in buildings with the same hot water distribution system. Given concerns in California at the time the research was conducted, ORNL looked at the impact that pipe insulation would have on a standard hot water use pattern in several different residential floor plans used in the development of California s Building Energy Efficiency Standards. The standard hot water event pattern used in the calculations is shown in the following table: Schedule of Hot Water Events Used in Title-24 Analysis Event Flowrate Time Before Event Flowrate Time Before Description (gpm) Event (min) Description (gpm) Event (min) 1 MBR shower MBR sink MBR sink K sink MBR sink K sink BR2 shower K sink BR2 shower K sink BR2 sink MBR sink BR2 sink BR2 sink BR2 sink BR2 sink K sink BR2 sink ORNL found that: 1. Adding insulation to copper and CPVC pipes exposed to air in attics and crawl spaces significantly reduces energy and water waste (about 50%). 2. Adding pipe insulation to copper and CPVC pipes buried below a floor slab reduces energy and water waste even more (about 65-75%). 3. Insulation of pipes dramatically reduces the waiting period for hot water to arrive for typical uses. 4. There is no benefit to adding pipe insulation on pipes buried in attic insulation. These results are significant because the standard draw pattern used in the simulations is based on 18 hot water events that are spread at least 15 minutes apart. As can be seen in the cool down graphs above, uninsulated ½ and ¾ inch diameter copper pipes that are exposed to room temperature air cool down in less than 15 minutes when the pipe temperature is 120F. They will cool down even more quickly in environmental conditions with colder temperatures, such as those found in crawl spaces, unheated basements, under floor slabs and in attics throughout most of the country during all but the summer months. Underslab environments can be even worse if they are damp, a situation which creates a more conductive heat loss condition. Only three of the 18 events would not benefit from pipe insulation: the first event in the morning (1), the first event in the afternoon or evening when people return home (10) and the first event in the late evening when preparing for bed (15). In each of these cases, the pipes will have cooled down whether or not they were insulated

226 UPC 2009 (Appendix L, L9.0) Since it is not known what the hot water use patterns will be in a given building over the lifetime of the plumbing system and there are significant benefits when the piping is insulated, it is reasonable to require insulation as part of the plumbing code. During the use phase insulation provides benefits by making hotter water available at the fixtures and appliances. During the cool-down phase, insulation provides benefits by extending the time it takes for the pipes to cool down, resulting in a greater percentage of hot water events when the delivery phase is significantly shorter. The greatest benefit will be found for those occupancies with consecutive draws on the same line from the source of hot water that are clustered reasonably close together in time. For occupancies with very intermittent hot water use patterns, it makes sense to install the water heater close to each fixture grouping minimize the volume of of water in the pipe between the water heater and the fixtures. The now shorter piping in these intermittently used occupancies should also be insulated, since the occupants will benefit during any clustered hot water use periods. We reviewed the pipe insulation provisions in California s Title 24 Building Energy Efficiency Standards, and the International Energy Conservation Code in the preparation of this proposal. Their emphasis is on recirculating hot water distribution system piping, although run-outs are included, as are the first 5 to 8 feet of pipe next to the water heater. Both codes allow for different insulation levels depending on the pipe diameter. It is our observation that it is harder to ensure that the correct level actually installed a wide variety of wall thicknesses are allowable. In order to simply the specification, installation and inspection for architects, engineers, builders, plumbers and inspectors, we have proposed only 2 wall thicknesses that are to be applied to all hot water distribution piping. These wall thicknesses are consistent with values found in both codes
