Product review (2 stars): Sad to say, it did not work for my water dispenser issue
I have a Whirlpool side by side frig with the ice maker attached inside the door. This gadget did not work to fix my water issue. I inserted boiling water into it 3 times......nothing.  Maybe it is b\c my ice-maker stopped making ice. We manually fill up ice bucket on the door to load it into the glasses outside the door.

 I was greatly disappointed!
