Active Sump Pump
Posted by Frank Monaco on August 16, 19100 at 09:16:17:
I had a new Zoeller Sump pump installed in my basement. It works well, but quite often. I noticed that the pit water fills up though no water is going into it from the incoming drain line. It appears the pit fills with water from the bottom of the pit up.
There is also a 8 second sound of "sucking air" after the sump cycles off.
Is this a faulty pump, check valve etc ?

My old pump did not have these problems>
