Soux Chief 653-B Hydra ester Water Hammer Arrester for Piping Systems

The installation is simple and straightforward. Size is a bit larger than I anticipated. Apparently to be well built and it's Made in the US. Works instantly and totally eliminated the annoying pipe noise.

Installed it on my washing machine hot and cold and on my dishwasher. I now forget sometimes I am washing as I got so use to the pipe sounds to tell me the washer is done. Banging of the water pipes is completely gone. Strong build , it seems durable as there was no metal flaking or compression while tightening it to the dishwasher line or washing machine line. Had no leaking.

This water hammer worked perfectly. It stopped the banging on each of my 5 sprinkler zones.

We had really bad hammering from our LG washer and I knew the little baby hammer arresters they sell at HD wouldn't cut it. I bought some 1/2" to 3/4" T's with a threaded 3/4" insert. Works perfect. Not even a little hammering. Silence! Only down side was, as others mentioned, the threads on these are awful. Minus 1 star. Absolutely use both Teflon tape and Plummer goo for no leaks.

Works great. I put it just upstream off my sprinkler valve manifold. Used to have a pretty loud banging from the pipes when the sprinklers went on and off, now there is no noise at all! $22 and some elbow grease, yesss!

I first purchased and installed the recommended AA size for my washing machine. On first use, the water pressure forced the pistons to the top of their travel and therefore had no effect on the water hammer. These larger unites did the trick! All good now. A bit of a hassle getting the proper fittings, but that’s to be expected. I’m including a photo of the finished installation. Only two recommendations. Use plenty of teflon pipe thread tape on the pipe threads, and minimize the use of garden hose thread fittings, as they tend to loosen easily. Good Luck!

just installed lawn sprinkler system. All is well but the water hammer at each and every zone shutoff time driving me crazy. no matter how to secure pipes, etc no help.found this one, 3/4in with 3/4 in pex tee and installed at the position right after the water valve in the basement where goes to the sprinkler system outside underground. amazing thing happened, no nosie, no more water hammer noise any more. wow, great.so anyone want to get rid of the annoying and dangerous water hammer, do it and you will be so relieved by the result.

Like others have said, the threads will likely be damaged. They really should have a plastic cover over them during manufacturing to protect them from damage as they are likely tossed in a bin before being boxed up. As it was, it leaked the first time, so I had to take it apart and file on the threads a bit to smooth them out.As for the hammering, it has helped, but not eliminated it. I still get one or two hits before it kicks in, but it is better than before.Other issue is that it says one day shipping, but it was two days for me, which seems to be an issue with a lot of Prime products any more. Tell me up front it will be two (or three) rather than suckering me into ordering it because you claim it will be next day.
