Review on Powerful Sioux Chief 660 HB Hammer Arrestor for Reliable Plumbing Solutions by Marcus Chavva

I ordered this to replace the 660-H I bought a few years ago. I use it on the back of my LG washing machines which have been causing rattling in my pipes. He began to bother and the knocking returned. This version has a stainless steel flash hider, which is not silver in the photo but is actually silver. The flame arrestor is also higher than the 660-H. After the replacement the noise was completely gone. no noise Hopefully it will last longer than the old all-copper version. If you are comparing it to 660-H I would recommend it as it has a higher capacity (higher) and stainless steel is probably a bit stronger than copper.
