This worked for us, thank goodness! Our pump was klunking so loudly in the basement it would wake me up during the night. Almost sounded like a door slamming!

Clunking still very loud after installing. Disappointed. Don't waste your money.

Leaks at the seem out of the box. I was able to fix the leak by tightening the four screws that hold the assemble together. However it had no effect on the water hammer. Save yourself the trouble avoid this value.

Rated 5.0 out of 5.0 by Csquared2 Very quiet check valve!
Our previous check valve was incredibly loud. Not sure why we lived with it for years. I saw this product passing by the aisle at Home Depot and am so glad I purchased it. It works well, no leaking and we can't hear it when the sump pump runs.
I installed it when adding a backup sump pump so the overall install was time consuming but this part was simple.

Rated 2.0 out of 5.0 by Plumber Klunkless - leaks at seam
Leak at seam on all 4 sides upon first test, brand new, out-of-the-box. Disassembled, inspected, reassembled, still leaks. Off to the return counter.

Rated 5.0 out of 5.0 by mare57mare This is the best purchase ever.
I had a plumber install it for $200 and the part was only $19. My daughters bedroom was right above the sump pump and whenever it rained she had to sleep on the couch. It mad a swish noise and then a boom, no longer can hear anything but a little tap. I just wish they would have made this 10 years ago. Maybe any bad reviews are from people who tried to install it themselves.

Rated 1.0 out of 5.0 by Spardon Junk, much better ones out there.
Installed this and tested it out and it had water leaking out of the seam where the two pieces join within seconds. There are a few reviews out there mentioning these valves leaking right out of the box. Guess I should have heeded their advice. It's a very easy install and actually is quiet, but they seem to have a quality problem in that the valve leaks. So no matter how quiet it is, or how easy it is to install it doesn't make much sense if it is going to leak.
