I have a sp-330d sump pump. When it shuts off,it sounds like a gun shot going off. You can hear it all through the house. I have tighten the discharge line down. That did not seem to help. I am also looking for a checkvalve that screws into this pump. Home Depot people can't seem to help me in obtaining one. Can anybody tell me who else carries it ? Thanks everyone.
