Product review (4 stars): It was a bigger pain to install that I thought ...
It was a bigger pain to install that I thought. My advice is to pick up spare couplings, razors, and ice box graded tubing from the hardware store before you attempt a replacement. I suggest getting the 1/4" and 5"16" tubing and coupling to make the tubs that lead into this a bit longer, and do not do it with the actuator valves in the back of the fridge. So far though all is working well.
