Review: Perfect fit - Works great, both blocking water backup and smell.
Review: Great to have a check valve - After reading a few other reviews I decided to check the material type. Screws and spring are all nonmagnetic indicating they are stainless steel. Brass plates are also nonmagnetic, everything looks good. I loosened up the screws until they were just attached then pressed in the rubber sleeve until it was free from friction contact to the brass plates. I then was able to push the unit into the 4" pipe by hand. Then tightened the screws a little bit going across like you tighten lug nuts on a wheel. This is the second check valve like this I used. The first one worked good for 15 years, just decided it was time. My neighbors had backwash problems but I didn't. After removing the original valve I saw turds at the surface of the water... Flushed them down with a hose and was very happy I had a check valve in place.

### ⭐⭐⭐⭐ Does the job!
*by J***K on March 23, 2026*

Great product! Best advice. Inspect periodically as the spring may break. And to make it much easier to remove, make sure the drain wall is as clean and smooth as possible and lube up the rubber seal with anti-seizing lubricant.
