Tee Water Hammer Arrestor，Clean Brass,1/2" Pex x 1/2" Pex

The media could not be loaded. It took literally 1 minute to install this water hammer and I’m not exaggerating, I literally forgot to review it because what used to be a house rattling series of thumps every time the washer would fill (6 loads a day) for pre-wash, wash, rinse, 2nd rinse is now nearly silent. Seriously it is worth every penny.

Our sprinkler timer would make our pipes violently “thud” when the water shut off, as there is around 70ft of water hammer in the lines. But this device definitely reduced (but did not eliminate) the noise the lines make when the valve closes by around 75%

I bought this for the timer on my outside faucet for the sprinkler to stop the hammering of the pipes. It was easy to install, but it did not stop the hammering. It seems that I will have to install two arrestors on the piping. I will buy one like the ones that I have one my washing machine and install it outside between the timer and faucet and keep the one in the inside plumbing. I tried it and it seemed to lessen the hammering so far.

Very Good and I'm happy

I upgraded the toilet in my RV and when you flushed it water line would shake not good could cause a potential leak after installing the air hammer arrestor waterline does not move a bit definitely worth the investment highly recommend

I'm not sure if this is good or not, didn't work for us but ended up being another issue.

I used product for my RV toilet water line , but it didnt work for my application. I believe my problem lies in the toilet flush valve spring.

Easy installation and eliminates the water hammer effects in the plumbing. I also like the compact design.
