Kyle: Replaced my noisy sump pump check valve with this one. There are several great features about this one:
1. Its spring loaded so its quiet(er)
2. Its clear so you can tell if its working
3. It uses rubber fittings and clamps instead or requiring PVC solvent and cleaner. That makes replacing it much easier
Overall good design and has been working well for about 6 months in the basement right under our bedroom. No more bang everything it shuts.

jmonico: Time will tell if it holds up. Easy to install. Spring and latch seem well made. At least it is see through so you can monitor it for blockages and function. I have good hopes for this product.

D. DeFalco: This particular silent check valve was the only clear-bodied one I could find that had slip connectors, versus the glue connectors. It was an easy replacement for my super loud existing valve -- which literally shook the entire house with a big boom! every time the sump pump ran. This Raybend valve is gloriously silent. The only thing I hear now is a quiet hum of the pump, and maybe some soft gurgling sounds in the pipes. Most times I can't tell when the pump is running, and it's wonderful. And it's cool to see the valve flap doing its thing. If your sump pump is a-thumpin, get yourself one of these, stat!

Chuck M: I couldn't believe these were actually working when I first hooked them up. I have two sump pumps, a primary and a backup. I replaced the check valve on the primary pump first. When I fired up the pump, I couldn't hear any water rushing through the check valve, and it made absolutely no sound when the valve closed. The basic check valve installed by the plumber on my new construction house had a significant "Bang" every time it closed, which is every 42 seconds with the amount of water flowing into my sump crock. I knew I didn't want to live with that sound more than 80 times per hour, so I searched for silent check valves. These are perfect! I send a photo of the box and an installed valve to my builder and told him they was no noise at all from them, and he said he'd pass on the info to his plumber for use in his houses going forward. If you currently have a check valve bang, replace it with one of these and the problem will disappear.

Nathan M.: Got a different style "silent" check valve from Home Depot last year that worked great for about 3 cycles then emits the loud clunk. Took it apart and drained it, reinstalled and same thing happened. After living with it for a year I picked up this valve. Works like a champ, no noise at all. Even made me get up in the middle of the night to check it as I couldn't hear it and I knew the basement was taking rain. My only hope is that the inner spring is made of a decent metal that won't corrode being wet all the time. I'll update my review if it breaks. No noise though!

Robert K.: I bought this check valve for my sump pump replacement project. The check valve was very easy to install. It is important to measure and cut the right size of opening in the outlet pipe to prepare for the check valve installation. I managed to get this exactly right, making the installation "easy as pie". Of course, time will tell if leaks develop around the joints, and how durable the product is (it has a 2-year warranty). Our sump pump seldom runs, so wear and tear shouldn't be an issue for some time. The one issue that was annoying was that I ordered the valve on November 27th and it didn't arrive till December 29th. It got hung up with the customs broker, or Canada Post, or a combination of the two, for 12 days. It wasn't clear to me when I ordered it that it would be coming from outside Canada (from the US).

Amazon Customer: The water hammer in my sump pump was getting so bad (and loud) that it was actually loosening the clamp connections on the check valve. The day I took a look at it and water squirted out of one of the connections and sprayed me was the day I started shopping for solutions.

Confession time: I actually bought another product first, one that required purple primer and glue fittings. I wasn't thrilled with the idea of that much effort, but I was desperate. USPS to the rescue! They lost the package, Amazon gave me a refund, and I got to re-order. This time I saw the Raybend product with flexible connections and stainless hose clamps. Second time's the charm.

It arrived today and it literally took me more time to walk to the mailbox to get it than it did to install it.

I plugged the sump pump in and held my breath. Amazing. I want to be clear, this device didn't diminish the water hammer, it didn't dampen it, it completely eliminated it. When the pump stopped, there was NO SOUND AT ALL. Zip, zero, nada.

As I've been writing this review, I've heard my sump pump cycle twice. Just the faint hum of the pump motor. And then no sound. I'm still braced for the sound...
