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.

Quiet valve

Would Recommend

Works great. Our old valve started water-hammering at 1:30 in the morning, needless to say we needed to replace it. This pump is quiet, pumps the water out, and was easy to install

Easy and cheap upgrade

Would Recommend

Works incredibly well, took away the noise that sounded like a mini van door slamming every time the sump pump cycled. Can still hear water gurgle when it runs so not 100% silent but huge improvement and at least some audile confirmation that the pump is working since I don't go down to the crawl space often
