Product review (5 stars): Works great!
My wife found a leak under the washing machine.  I took the back apart and couldn't figure out where it was coming from because it would leak when it was on, but the water wasn't coming straight down from the valve because the spinning drum would shoot the water to the sides.  Then I took the top of the machine off and by luck saw the water pooling around the vertical white shaft of the valve.

Good thing the washing machine's panels were easy to remove and this valve was easy to change out.
