Rated 2.3 out of 5 by 3 reviewers.
Rated 1.0 out of 5.0 by Not Klunkless I had two of these valves installed. They did not get rid of the noise. Don't buy this check valve. February 5, 2016
Rated 1.0 out of 5.0 by Doesn't Reduce the Noise As Much As I Expected From the design it seems like it should work, but it just doesn't. It does SLIGHTLY reduce the noise, but the noise is still about 75% of what it originally was. I was simlpy disapointed. I thought it would work but it just didn't, after the expense and the effort I can't recommend it. April 22, 2014
