What Does the Diagram Show?
A riser diagram shows all the drain, waste, and vent (DWV) pipes that will be installed by you or the plumber. The building department wants you to prove to them that you know the correct size for each drain and vent for each fixture.
The drawing also shows the correct fittings to use. Many DIYrs use the wrong fittings. Clogs can happen with ease when you use the wrong fitting at a junction point where one pipe connects to another.
Follow the UPC
The Uniform Plumbing Code (UPC) must be followed when you design your basement bathroom. The code is very complex. It has its own lexicon that will seem like a foreign language should you not be a plumber.
Gravity Flow vs. Sewage Ejection Pumps
The best basement bathroom has gravity flow. Gravity flow is achieved when your septic tank or the city sewer tap outside your home is lower in elevation by several feet from the underside of your basement slab.
A sealed sewage ejection pit and pump is required where there is no gravity flow. The waste from the basement bathroom flows to a sealed pit or sump. A pump inside the sump then pumps the waste up to the main building drain where it can flow by gravity to your septic tank or the city sewer.
Special dedicated vents are required for these sewage ejection systems.
