Product review (5 stars): leaky fridge
My brother's Whirlpool refrigerator started occasionally pooling water on the floor. Discovered online it was the rubber valve on the drain tube getting dirty and not opening. This supposedly was the fix. I bought 2 as I have the same fridge only newer. I haven't had the trouble yet but replaced it anyway. I could see the rubber valve was already quite dirty. Very sticky. Would not be easy to clean. Replaced my brothers' and have not had the leak since. It's been over a month.
