Okay, so I'm not exactly your regular ol' handyman. My kitchen sink started draining VERY slowly, so I turned on the garbage disposal. It just sat there humming like it was trying to go, but couldn't. Then the circuit breaker turned it off. I've reached my hand down there to try to find the obstruction (I'm not missing any dishes down there) and can't find anything. I turned the circuit breaker back on and tried it once more; no go. Any ideas on how to unstick?
