What Customers Are Saying

The product appears to be an effective and quiet solution for addressing water hammer issues caused by sump pumps. Most customers report that it virtually eliminates the loud banging and hammering noises, allowing for peaceful sleep. Many praise the valve's quiet operation, with several noting it is "very quiet" or "silent" when the sump pump shuts off. The clear casing is also highlighted as a useful feature for visual inspection. While a few reviewers noted minor issues, the overall consensus is that the product effectively solves the common problem of noisy sump pump check valves.

Lid/valve spring is too strong?

The lid/valve stuck shut after the first use. I suspect because the silt from the stirred up sump was creating some kind of unintended seal. Pump I have is strong enough, so I don't know... it has worked since, but I am scared now and have to keep checking. Might have to change it.

One if our 2 sump pumps began banging after the pump shut off. I looked to Lowe’s online and this product caught my eye. Easy install and eureka! This check valve made absolutely no noise. I definitely recommend!
