Product review (5 stars): Easy to install - eliminated pipe hammer.
My house was built in 1961 and has pipe hammer fairly frequently. This outlet box and arrestor were easy to install and the annoying pipe hammer that happened with my old fridge setup are gone. I am not a plumber, but working with PEX pipe and SharkBite fittings could not be much easier. The outlet box made for a very tidy and professional looking installation.
