In response to Re: will a sump pump drain work as a vent?
: I'm adding a sink and washing machine to a basement. I can easily drain them into the main stack. But finding a place to vent each is difficult. Nearby is a sump pump and a 2 inch drain pipe that goes up to the ceiling, accross to the outside wall, then down about 6 feet, and out the back of the house. Can I tie the new vents into the sump pump drain--even though it goes up and down--since the end of the drain is outside?


No you can't,even if you pipe it so the pump can't dicharge down the vent and sink drains the sewer gas will still come out of the pipe. There are "cheater vents" available and may be legal in your area
