If the plumber’s putty has failed, you might be able to stop the leak by replacing the putty. To do so without removing your garbage disposal, loosen the retaining bolts until a gap forms, force the new putty between the pipe and flange, and retighten the bolts to secure the putty into place. If this does not work, then remove your disposal unit and reseal the flange. To do this:

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.
