I purchased a house with working sump pump/radon mitigation system. I was
concerned if the sump pump was working. I unplugged both plugs and just
plugged in the pump and it worked. However since its sealed shut for the
radon mitigation system, I didn't know if it was possible to remove the lid to
test the arm that goes up and down to tell it to run. I checked this morning
after the rain and there was some water on top sump pump lid. Is it there a
procedure to remove the lid and break the seal of the radon mitigation system
or should I just hire a plumber?
