Perhaps you’re planning a playroom for the kids, a rec room for the teenagers, or that long-awaited man cave. Essential to the plan is a basement bathroom so folks don’t have to pound up the stairs whenever nature calls. Every active home can always benefit from an extra bathroom, but adding one to a basement brings a few challenges. Check out these special plumbing needs before you forge ahead.
Some lucky homeowners may find that their sewer and wastewater lines are deep enough that their bathrooms can be constructed in the usual way, using gravity to drain the waste and water just like in upper bathrooms. There may already be stubs of plumbing pipes available for instant hook-up.
But even in this best-case-scenario, a plumber will have to make sure that the flow rate is fast enough for the fixtures you want to install. Also, a plumber will have to determine whether a back valve should be installed to the sewer line to prevent a smelly backflow to what will likely be the lowest access in your home.
