What is the proper slope for a drain pipe in a DWV systems?
The local code dictates what slope is required for each pipe size. Typically, 3" and smaller DWV pipe should pitch no less than 2% or 1/4" per foot. Larger than 3" should pitch 1% or 1/8" per foot. The pitch also can be dictated by the amount of fixtures connected to a particular pipe. You may be able to pitch steeper with more fixtures connected without changing or increasing the pipe size. This all would have to be checked with the local building and or plumbing code.
