Review: Small job, large return - These arrestor did a great job and they are very easy to place. Every time I used my washer it sounds like it was banned several times and after reading on Google, I found out that it was a problem with getting air in my water pipes leading to the washer. We attached these and we've had no trouble since.
Review: Inexpensive and solved a major problem - After getting a new washing machine, we were getting water hammer in our pipes. Thought the pipes were going to pop out of the walls. Plumbers, appliance techs, etc. kept pointing fingers at each other. This was recommended to me by a relative. Problem solved immediately. So simple. So smart.
