Product review (5 stars): solves a potentially expensive problem cheaply
Since Kenmore/Whirlpool isn't decent enough to own up to the poor design of their original duckbill drain valve for certain models of their refrigerators, this aftermarket part is your best option. This solves the problem of water pooling in the bottom freezer until it spills out of the bottom and onto your floors. Installation is relatively easy if you're handy.
