I have an Emerson E20-27 garbage disposal that starting leaking from the bottom of the unit today. Before it starting leaking I was running the disposal. Something was in the disposal that wasn't supposed to be. It didn't jam, seize, or trip the breaker, but I could hear something in there. I can't find any manuals or solutions. I haven't removed the unit yet, but I'm concerned that I may have cracked the casing. What broke? A seal or maybe the case?
