Product review (1 stars): *WARNING* RISK OF FLOODING DUE TO UNIT FAILURE!!!
Don't waste your time and money on this cheap alternative. I, like another reviewer, experienced the horror of finding water dispensing itself all over my kitchen floor 4 days after installing this valve. The valve was stuck in the open position, allowing water to flow freely out of the refrigerator door dispenser. Had this not been caught quickly after it started happening, there would have been major flood damage to my kitchen.

What if the problem had occurred while we weren't home?

Supco is just asking for a lawsuit by producing a unit that fails in such spectacular fashion.
