Product review (5 stars): Efficient Replacement of a Failed Drain Design with One that Works
What an incredible practical DIY solution for a leaking refrigerator defrost system.  This YouTube video (http://youtu.be/Tk24ISRzSRs) was very helpful though my Whirlpool refrigerator is a different model.  The DIY explanation and repair is a great example of how the internet can provide information and guidance that was otherwise unavailable "in the old days".  I would have been charged at least 100 to fix a problem for which this part cost me less than 20 and an hour's time on my hands and knees behind the refrigerator.
