TT FLEX Stainless Steel Water Hammer Arrestor 3/8" male compression and 3/8" female compression For For Dishwasher and Toilet Stop Hammering Reduce Banging

I gave these a five star rating understanding "how" they work and how "well" they should work where I put them. They are of good build quality and easy to install and use. As they have a spring in them, they are not noisy and, in the supply line to my main home toilet and my refrigerator water supply, they stop the "hammer". However, at the very end of the house with only one way for the water to go (back against the 80 psi supply pressure) they are less successful in reducing the hammer...but they help! I am satisfied with cost and recognize that in a few years I'll need to replace them (as the spring wears out) but I'm happy with that and them. I'd buy them again.

These fixed my water hammer issue on my bathroom sinks. Both sinks come off the same line, but I had to put one on each sink, so glad this was a 2 pack. Easy to install.

Works like a charm! when I removed the dishwasher I started getting the water hammer noise. And that line had a suppressor but the regular hot water did not.Very easy to install in about 5 minutes. Great price,seems very sturdy and super easy to remove. They fit perfectly

Worked great, easy to install and stopped water hammer when turning off sink.

Works as intended and easy to install.

Easy to install, but did not help reduce pipe banging after water close.

Solid construction. Easy to install. Not completely solved my problem but muffled the noise.

I bought 2 of them to fix the water hammer problem in my kitchen sink. i installed them one in the cold and one in the hot water line.in the. I am very disappointed that they did not fix my problem. The noise from the water hammer stays the same as before.
