Product review (5 stars): Worked perfect. Water was down to a trickle and ice ...
Worked perfect.  Water was down to a trickle and ice was nonexistent.  I figured that the hard water/calcium buildup was the culprit.
Was able to install in about 40 minutes.  Much of that time was spent cleaning up the water that came out of the last hose I took off from the old unit.  There must be a holdin reservoir in the fridge, and when I disconnected the last hose for the old unit, water came running out.  Probably close to 4 cups worth.
Once that had drained, I put the new one in place and reconnected the hoses, connected the wiring terminals and tightened on the compression fitting for the water.
Had good water flow in seconds.  Was worried about ice because I didn't see water going into the tray.
After 2 hours hiwever I heard new cubes "clunk" into the ice holder and new everything was golden.  This new valve worked perfectly for me.
