Hi all:
I opened the cabinet under the kitchen sink to get out the dishwashing detergent and there was a puddle of water under there. After 15 minutes of poking around, I have come to the conclusion that the leak is coming from the side of the garbage disposer unit under the sink. Of course, the leak is on the back side, so I can't really get a good look at it. From what I can see, there are a number of chalky white spots (looking much like oxidized aluminum) in a ring around the periphery of the unit, and the water is coming from one of them. Do they make these out of aluminum? That might explain how it could wear through. I plan to pull it out and see for sure. For the sake of curiosity, I thought I'd ask if anyone has seen one wear through its housing. This unit is a 15 year old In-sink-erator Badger 5.
