Product review (5 stars): Water Inlet Valve
I had a problem with inlet water supply leading to my ice maker not shutting off properly.  After filling the ice tray the water would continue to slowly leak by causing the line to freeze and making an icy mess of my freezer.  After coming home one morning and finding about 10 gallons of water on my floor and seeing water constantly flowing from my ice maker, I did some research and found that the problem I was experiencing was caused by a bad water inlet valve.  Purchasing and installing this valve corrected my problem.
