will a sump pump drain work as a vent?
Posted by Jerry Cooper on March 12, 2002 at 22:40:49:
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?
