Introduction

Water damage is one of the most difficult disasters to deal with. A leaking sink can flood your cabinets, create mold and cause thousands of dollars of damage. I have prepared a relatively simple and inexpensive fix to repair a leaking garbage disposal without the hassle of calling a plumber and spending a larger amount of money. This fix requires a screw driver, a hammer or chisel and Plumber's Putty.

Unplug the garbage disposal from the power source.

Loosen and disconnect the dishwasher drain hose from the garbage disposal unit.
Do so by loosening the clamp and unscrewing the screws with a flathead screwdriver.
Remove the screws and pull the gray tube from the disposal.

Step 3

Remove the three screws from the flange at the top of the garbage disposal unit. These screws are at the top right above the black disposal box.
Disconnect lock-nut at flange.
Adequate lighting is imperative for this step.

Use screwdriver to turn locking ring counter clock-wise disengaging drain hose and disposal.
You will be able to hear the locking ring come undone after pushing it forcefully to the left.
Disposal will drop down. When disposal falls catch and place on bottom of sink.
Move from underneath the sink to the top of the sink.

Step 5

To remove flange you will push from underneath the sink with one hand and pull it out through the top of the sink with your other hand.
Scrape off ALL excess putty from flange and sink.

Remove small ball of putty and roll into golf ball shape.
Roll flat until putty becomes snakelike shape approximately 3/4 inch diameter.
Be sure that putty is long enough to wrap completely around flange.

Step 7

Roll into snake-like shape until long enough to fit fully around flange.
Wrap around flange and place flange back into sink.
Press down hard into sink and remove any excess Plumber's Putty.

Step 8

Reassemble flange and garbage disposal reversing steps.
Put sink stopper in and fill up sink approximately halfway. Remove stopper and check underneath sink for leak.
