Product review (4 stars): Didn't need it!
I had bought a new set of braided hoses for our washing machine. After installing the hoses there was no cold water to the washer. I believed the valve had gone bad but it turned out the hoses were a type with a restrictor inside to prevent overflow. Installing the new valve didn't help the problem. The hose was blocked and the original washer valve was okay. An expensive lesson in washer repair.
