PumpSpy Silent Sump Pump Check Valve - 1-1/2 with Buna-N Couplings, Model CV-150, Spring-Loaded Flapper, Quiet Check Valve, Sump Pump Life Expectancy Increase, Includes Steel Clamps Fit 1-1/2″ Pipe

We replaced both of our sumps and check valves but the valves we bought would make a loud banging sound when the pump shut off. We installed these and no more noise! Easy to install, Definitely worth buying!

After living my house for 30 years, always heard the pump going off in the house. The past few months it was getting louder, replaced the check value and after a few days the banging sounds are back. Did a little research online, and came across this check value. Don’t hear a sound now when it’s going off, don’t wait any longer to purchase!

Was exactly what I wanted, works as promised.

Quietest check valve Ive ever used. Appears to be a quality piece. Time will tell. Its been in for a few months and so far so good!

Quite I’ve done 3 different versions this is actually quite no hammering or loud noise. Easy install 30mins to do both my main and backup sump. Highly recommend this product. 2 year warranty on parts.

ITS UNREAL I WENT FROM A CLUNK THROUGHOUT THE WHOLE HOUSE. ITS A BIG HOUSE 5000 SQ FT TO NOTHING. I MEAN NOTHING. I CAN THEAR THE WATER GOING TO THE PIPE IN THE BASEMENT WHEN I AM THERE TO ZERO. BUY THIS........

My 35 years old well pump and plumbing has seen many component replacements. My most troublesome component has been the check-valve. Up until now I had used brass valves with spring loaded axial shutoffs and each one had a disappointing short useful life. This valve has a flapper shutoff which I truly believe will outlast all the others. Time will tell, of course, but this design is simple, old, and proven. The installation was a breeze and the buna-n rubber couplings did not leak one drop.

Needed a check valve since my installation didnt have one to begin with. Took 5 min to install (PVC cutter made it a piece of cake). Very efficient valve, doesnt make any sound. Plus, its visually satisfying to watch it operate. Highly recommend!

Sump pump in basement directly under master bedroom. This was our first spring in the house. The Ck valve on the sump pump would close very loud effected our sleep. Found this Ck valve and gave it a try. No more noise, would recommend and would repurchase.

Now Im concerned whether my sump pump is working or not! I cant here the hammer sound anymore! My pump runs constantly end of winter/spring so Ill be really impressed if this lasts 2-3 years....
