How to Fix a Leaky Garbage Disposal

A leaky garbage disposal is more of a nuisance than most kitchen repairs. Not only is the water slippery and dangerous, but it can cause your kitchen cabinets to rot, pipes to rust, and even ruin the contents under your sink.  The worst is certainly the smell!

Fixing a leaky garbage disposal is usually a project you can do yourself, once you’ve located the problem.

All you will need for the task is a screwdriver, a flashlight and plumber’s putty.  

Once you’ve identified the source of the leak, turn off the water and disconnect the power to the garbage disposal.

While you’re at it, you might as well spruce up the entire system. Identify where your disposal connects to the sink. At the connection you should find several screws covered by plastic. Remove the plastic and screw all the screws in tightly.

Repeat this process with the drainage pipe at the bottom of the garbage disposal unit.

At this point, reconnect the power source and turn on the water. If your problem is solved your garbage disposal should no longer be leaking. If water is still seeping out around the screws you will need to reinforce them.

Turn off the water and power sources again.  

At this point, chances are that the pipe connecting the sink the disposal has been damaged. Unscrew the connecting screws and carefully remove the disposal. Before applying plumber’s putty read the directions!

Apply the putty around the flange of the connecting pipe, and then push the disposal back into place. Make sure to screw the screws back in as tightly as you can.

Wait as long as the directions specify for the plumbers putty to dry. Make sure the seal has set before reconnecting the water and power. Of course, run the water to make sure the job has been done right. If there is still leakage, you may have to replace the pipes.
