Straight tees, elbows, and crosses may be used on vent lines. Make no change in direction of flow greater than ninety (90) degrees. Where different sizes of drainage pipes or pipes and fittings are to be connected, use standard increasers and reducers of proper size. Reduction of size in horizontal drainage piping in direction of flow is prohibited. 3. Drilling and tapping of drains, soil, waste, or vent piping, and use of saddle hubs and bands are prohibited. 4. Connect piping to fixtures or equipment by couplings or unions so that devices may be replaced with no disturbance to piping. B. Exterior Drainage Systems: 1.
