“Super quiet as advertised, but after installing it, it bothered me that I couldn't hear it working. Because it is so quiet. So I thought it is better to know that my sump pump is working. So I put my old noisy one back on. Lol”
“Excellent check valve! It completely eliminated the water hammer/knocking. The video attached doesn’t convey the loud reverberation that existed with the previous valve. It was driving my wife and me nuts! Very glad we made the purchase. Don’t mind the sloppy primer”
“I thought it would help to reduce the "bang" when the valve closed but it made the whole system so quiet that I can't hear it running anymore... For roughly $30, don't you think plumbers would offer this as an upgrade?”
