But to dislodge whatever’s causing it to be in a bind you can use the hex wrench that came with the garbage disposal. I know most people lose them, that’s okay. Grab your set of Allen wrenches, get the right size, insert it into the recess hole right in the bottom of the disposal, and turn it left and right until you dislodge whatever caused it to get into a bind.
Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
