Product review (4 stars): Could  have used a few more instructions.
This valve looked the same as the one I replaced on my  Whirlpool fridge and was easy to install.  One large set of plugs, one small.  Tubing on one side slightly larger than the other, no problem.  Then when I went to try in out, the door water side was flowing into the ice cube tray - what a mess.  What the instructions don't mention is that you may have to reverse the connections on the valve by flipping the two regulators on top  of the valve.  After awhile of trying to figure out how to make this valve work on my fridge, I came up with the fix myself - no thanks to the instructions.  Otherwise, the valve works fine and I now have much more water pressure to my door water and a full tray of cubes.
