Hi,
I recently decided to cover my sump pit properly to ensure lower radon levels. I therefore decided to replace my pedestal pump with a submersible pump since it was easier to cover. I barely ever seen water in the pit in the 20 years since we've purchased (new) that house.
Now, I wonder why do I have a return pipe to the sewer as well as a pump. Also, given the return pipe to the sewer, should my sump pump be set to pump when the water level is lower that the return pipe or the pump is just there in case the return pipe can't suffice? Any help is appreciated!
