I'm getting close to drywall in my river house basement finish project.
Six years ago I did several things to dry up a wet corner, including installing a sump pit and pump. Apparently the combined improvements worked. Everything has been bone dry, including the sump.
Before I drywall over the sump discharge pipe I want to install radon mitigation forced venting. But I want to avoid installing a vent pipe at this time. ....I missed the chance to do this easily.
I see two approaches:
1) Tee the vent into the discharge pipe, with a backflow preventer in case the sump pump ever activates. (seems very unlikely). Seal the sump bucket cover and discharge. Cut the exhaust blower into the sump cover.
2) Seal the sump bucket cover and discharge. Cut in the blower, but use it to pressurize the pit. If there isn't enough outflow past the pump impeller, drill a few vent holes in the discharge pipe above the pump to cycle air through the pit.
Thoughts?
