Query: Have an HE washer???? Buy two of these.

Wasn't aware of the water hammer issue until after we bought a (GE) HE washer. Hammer was apparent and strong from load 1. Researched the net a bit and bought two of these. Installed in 5 minutes (or less) with a pair of pliers simply to loosen/tighten connections. Connected on the washer end of the inlet hoses. 100% fix to hammer problem for not a lot of money. Should be included/required with all new HE washers
