Campbell FBA_B-0823-20 CHECK VALVE QUIET WHT 2" [Misc.], No Size, No Color

Product works no more hard thud when the pump shuts off problem solved! I gave it 4-stars since it was a solvent weld vs. no hub install. But it works great. You will still hear water pass through it but definitely no more thud at pump shut off.

Easy install and eliminates the bang when the valve closes.

Easy to install comes with everything you need to install on 2in pvc besides the pvc glue and primer. Took away the water hammering which has been waking the kids up for years. Don’t even hear it anymore!

Working great

Consider that I am a DIY home fixer as you read this review.For years I have done business with the largest plumbing supply company in my town of 500,000, have an account with them, and consider their advice to be near golden. For all those years I have maintained a sewage sump pump in our basement which has required replacement of the 2" check valve about every 10 or so years. The last one this supply house sold me had a spring in it, operating a ball type valve, and it was relatively quiet and flawless in operation until years later the ball seat began to leak. So, I went back to buy another only to be told: "You don't want a spring operated valve!" A web search brought this check valve to my attention and you can understand my consternation when I read that it was operated by a stainless steel spring. Well, I just finished installing it and my response is one word: WOW. The thing is so quick and quiet that I have to stand next to it to know if it is working.So what about the spring problem? Well, remember the last one the supply house sold me was spring operated? It lasted years, and reading up on the subject showed me that several companies now manufacture large, up to 11 or more inches, spring operated check valves for industry. So, I am willing to take my chances. In the meantime, my sump pump, house, and occupants are enjoying the gentle closing of the valve, rather than the wall rattling jarring typical of flapper style valves.2016 UPDATE: This check valve has been flawlessly working since it was installed and I am happy it is still stocked by Amazon.

Couldn't find a local store with a 2" quiet check valve, so was happy to find it on Amazon! I just installed a new ejector pump, but went with the standard check valve and ended up having to listen to a thump every time the pump ran. Replaced it with this one and am absolutely satisfied that I won't have to listen to that noise again. Obviously can't comment on longevity, but if I have to replace it every year, that's fine by me. Do yourself a favor by following code and install a ball valve downstream or you'll have a potential mess to deal with if you need to replace the check valve.

This check valve has solved by loud banging noise on my ejector pump. For years I was trying to figure out why my pump was so loud. A friend then recommended I and a new check valve so of course the first place I came was amazon.I found this valve, purchased it, relatively easy to install (some handy man skills required) and ta-da....no more noise.The flap inside of this valve must be a slow close so that it does not bang at all anymore when the pump stop shooting the water up the pipe. The noise I use to have was so annoying it would shake my entire house and even wake me up in the middle of the night. This valve stopped all of that noise and has functioned well since installing it!If your pump emits a loud "bang" after it stops pumping, odds are you have an old school check valve that slams shut! I would highly recommend this valve to help you stop that "banging" sound!

I had a new bathroom and ejector pit installed in my basement a few months back and of course the contractor used the cheapest check valve he could find ( that's construction ) and it slammed shut and you could here it though out the house. I installed the Campbell valve this morning and ran the water to check how quiet the new valve was, I was standing right next to it and you could barely hear it. So I am back on Amazon buying Campbell's 1" 1/2 quiet check valve for my sump pump which i can here when it goes off, but I'm sure after I install the new valve I will never hear again.

J'ai installé le clapet dans fosse de rétention au sous sol et on entend que l'eau qui coule plus de bang lorsque la pompe arrête merveille de silence bravo

As many others has already stated, this valve is very quiet. Our old valve rattled the pipes so badly you could "feel" it in the floor upstairs. I was worried that the shaking would eventually damage a drain pipe and cause a water leak. The new valve is amazing. The only noise I hear now is the gurgling of water that is flowing though the pipe. When the sump pump turns off there is no clunking or vibration. Its music to my ears!

the valve solved the annoying hammer noise from standard check valve on my sump pump in my basement. it is quiet. it performs as advertised and is worth every penny.

its is quiet
