Good quality check valve
Would RecommendCheck valve works well and I used it to replace a cheap check valve that failed but unfortunately I did experience it leaking initially. You can only get the provided clamps so tight so I used some sealant at the ends to stop the leaking.

Silent as advertised.
Would RecommendThis is a fantastic product. The check valve that was installed with my sump pump was very loud when the sump pump would shut off. This valve was silent. I highly recommend it.

Rubber coupling Leaks
Would Not RecommendJust like I read in other reviews it is subject to leaks at couplings. I have gradually tightened the clamps to stop outlet end leaks. To no avail. Now I added a second clamp next to the one provided. We'll see! Not hopeful.
