Product review (5 stars): Jon F.
We installed a new dishwasher a few months back and it works fine.  However, when the water supply solenoid swiched on and off it sounded like someone was whacking the kitchen floor with a brick.  We tried securing the supply pipe and insulating it from any adjacent wood to no avail.  A friend, who is a plumber, mentioned that many new dishwashers have this problem and that we needed a water hammer arrestor. This unit installed in minutes and totally eliminated all of the noise.
