Had to do a little repair work this afternoon - the garbage disposal had been leaking. Once carol removed all the items from down below the water damaged wood revealed the extent of it. Ugh. Luckily, replacing a garbage disposal is really not that difficult. Kill the power at the breaker; remove the unit from the power; disconnect from the plumbing; rotate it off the mounting ring at the sink; take to home depot and buy a (slightly) better one; come home and do it all backwards.
If i wanted to modify my plumbing, i could have bought a much quieter, more powerful version than the Insinkerator, but seeing as how i didn't want to spend all afternoon doing this - i went with the same brand (same hookup) and popped it back in in 15 minutes. 3 year In-home warranty.
