Review on 🚰 Solimeta Water Hammer Arrestor with 3/4" GHT Thread for Washing Machine, Toilet, and Air - Set of 2 Pieces by John Iverson

For years the pipes in our house would bang against the walls while we were doing the laundry. We recently got a new washing machine and I realized I had to do something about it. I bought them and installed them in the washing machine faucets (along with the inlet hoses). Instant difference! I would say about 95% of the knock is gone. I only hear that now if something else in the house is using the water at the same time as doing laundry (e.g. someone showering at the same time). I suppose it's because of the added dynamics of the water when two things work. Even then, it's not as bad as it used to be. I would definitely buy again.
