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

I bought this valve because the one installed by the builder is so noisy and wake me up at night everytime the pump runs. After installing this valve, it is super quiet, I cannot even hear it and have a good sleep. Love it.

The old one knocked off so hard and loud I thought the neighbors could hear! Now I need to check and see that the sump pump is on! Silent! Did it myself - easy.

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!

Best thing to buy for my sub pump. No more noise and super easy to install. Would highly recommend.

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.

Works just as described.

Compared to the valve it replaced, this thing is a gem. The thump thump thump (17 times each cycle) is gone. Slightly longer pump cycle time, but very reasonable. Easy installation, real test is coming this spring.

Does not make thumping sound, clean and gives you confidence thats working. Easy to install. Highly recommend it.

Tired of the cheap builder grade hammering loud check valve and bought this gem. Wish I knew this company was local and I would stop by and just bought it. Excellent valve and 100% quiet

packaged well, product features, and nice qualitu
