I thought I'd share my fantastic trick to unplug a sink disposal. I mean a really bad one where you can't just spin ice or fill the sink with hot soapy water overnight or use a toilet plunger (when a dishwasher airlock is there to break the suction). And you don't want the mess of disassembling plumbing which may not be that simple due to old style pipes, and of course you don't want to call a plumber (last one charged me quintuple of what's fair and stole some of my supplies).
The trick is a wine cork. Stick it into the dishwasher drain hole in the sinkerator, whittling it down if needed. I did it from the inside to avoid any messy disassembly, with my fingers just clear of the chopper blades - you can do as you like. Now partially fill the sink and pump with a toilet plunger and voila! Remove the cork and say thank you Sir Dumbstruck! I hope some of you will be joining me at the ceremonies to give me the Nobel prize in amateur plumbing.
P.S. the root cause of this was insufficient water flow while using the disposal due to a cheapo one handled faucet rebuild kit. I got a plastic ball to replace the metal one and worried about it's floppy guide peg. Sure enough it went loose and made it hard to turn water all the way off or on. Gotta find the old metal ball and refit...
