2PC EFIELD Tee Water Hammer Arrestor,3/8" OD Comp. X 3/8" OD Female Comp | Stainless Steel Water Arrestor For Faucet, Dishwasher Connection,MH-231-2-FM-HAMMER013(2)

Wife had noticed some very mild hammering with her bathroom sink. We tried the free method of shutting off water main and opening taps; that didn't work. These were easy to install in minutes, and the noise vanished and has not returned.

Well made product, meets expectations. Works well

total waste of money. i've installed two on each of my toilets as was getting a loud pipe bang when the flapper inside toilet would close. the bang still is present.

As a plumber these are great items. Very easy to install and perform perfectly with no leaking. Extremely durable and affordable price. Perfect for homeowners looking to fix that water hammer for a great price and cutting the plumber out.

Install at toilet and kitchen faucet. Hammering pipe stopped

Got them and installed today. Once you identified which fixture causes the water hammer, install it on the supply line or lines to that fixture and it will work. How long will it last, we will see.

Just received it today and installed it inline from the water shut-off valve for use on the automatic sensor faucet. Easy to install: 1) Shut off the water valve. 2) Remove water lines. 3) Attach the arrestor to the valve. 4) Attach the water line to the arrestor. After installation, the loud banging noise from the pipes was reduced. Hoping that it continues to work for a while as I saw in another review that it only worked for 2 months.

I installed these in the supply lines for a faucet. One of them worked and stopped the water hammer. The other one did not work at all. I reached out to the manufacturer a week ago about a remedy for the defective water hammer arrestor, but have not heard back yet. I purchased another two hoping that at least one would work and I could finish the faucet. However, neither of the two new ones worked. Poor quality and poor value

Works perfectly, no water hammer when the new Delta H2O faucet solenoid closes.

Facile à installer. Pour l’instant, il semble bien faire le travail pour lequel je les ai achetés.

I purchased four of these water arrestors. The connections on three leaked. After wasting time trying different options to stop the leaks, I threw them away.

I did see the bad reviews on this arrestor, but gave it a try, since it's half the cost of the Sioux Chief equivalent (660-GTR1B). Those previous arrestors lasted about 3 years, which I think is a decent lifespan, given the hardness of the water in this area. The installation was straightforward, and this device did stop the water hammer effect on our cold water supply line for the kitchen sink. I can't give it a 5 star because length of service is important in these devices. If it lasts 2+ years, I'd give it a 5 then.

Basically didn't do anything. The sound may be slightly less loud than before, but no exactly what I expected.
