Camis CC00SL15 - 1-1/2" Clear Silent Check Valve

Replaced a noisy check valve with this model. Very easy to install, and this check valve ended the loud thud at the end of the pump's cycle. Now I will have to get used to a pump that cycles quietly, and trust that silence is golden and that everything is working properly without the added noise. Couldn't be more pleased (actually a little proud that I was able to install this check valve and correct the problem myself), and really glad to have found this solution on Sump Pumps Direct.

Well it worked for the first 3 days then it stopped sealing and leaked back to the pump. I have been pumping steady for a week. We have bad flooding in my area and I did not need this now. It will be over a week before I can replace it. It was somewhat silent when it worked but I would never buy one again. And I hope this does not damage my pump.

My husband & I purchased an 8 yr. old home the end of October 2016. We knew there were 2 sump pumps in the basement, one at the front of the house & one towards the back. We never heard a peep out of them until after our 1st snow storm Dec/Jan ? & everything began to melt. It was every 45 seconds sometimes less, we would hear a loud clunk sequentially. It even kept my husband awake some nights. Eventually they slowed up until April/May showers . Once again the constant loud clunking. This is when my husband began researching & found your valves. They are utterly amazing! We hear absolutely nothing at all. I helped him install them, it was easy. We would highly recommend these valves, we know longer regret purchasing our home.

Works as advertised. You can see it working, very quiet and easy to install.

This is the second I've purchased for a reason, no clunking when the pump shuts off. This is a replacement for one I purchased about two years ago on a pump that runs quite a bit. It's right below my bed so when it went bad it woke me up, not anymore. Keep up the quality products and you'll have my business unless I move to the dessert.

Works great! before installing this my sump pump was very loud when it shut off, a loud thud could be heard everywhere in the house, this is super quite, I can't hear it at all. Well worth the purchase.

I have not used it yet but the quality is great. I did make a back up sump pump with it so if the other one goes out I can put it in and I'm good to go. Had to have a good quality everything cause water in the wrong places is not good.

I replaced a very loud, annoying flapper check valve with the Camis and it is essentially silent. Easy to install, made in the USA, what's not to like.

This was worth every penny! So tired of the clunk of old check valve. My sump pump goes off a lot. So quiet now! Thanks for the recommendation! Haven't had long enough to know quality. I am sure it will last a long time.

Very quiet as advertised. Was easy to install (1/2 hr.) and is so silent, I don't even know that I have a sump pump. This product is great and worth every penny.

The check valve that I replaced worked but sounded like someone bouncing a basket ball in the basement every time the sump pump would run (it drove me nuts). The Camis silent check valve is just that "silent" the pump runs and stops then nothing not a sound. You can't hear the sump pump run unless your standing right over it.
