“This relieved me of the constant banging of my old check valve.”
“Pretty easy to install. Gets rid of the water hammering noise instantly.”
“I no longer get a huge flap closing noise in the middle of the night. It's built very strong.”
“Completely eliminated the loud clunking sound my old valve made.”
“Spent two years listening to a loud clunk every time our sump pump ran. This got rid of it completely. Highly recommend.”
“Bought the other ones etc and ehh worked ok. But my thump thump thump is gone…”
“Works but sometimes causes the sump pump to gurgle when it shuts down. I can hear this because it’s my room is directly over the sump.”
“It’s so quiet I went to see if it was working.”
