Why Is My Garbage Disposal Leaking?

Garbage disposal leaks can come from a worn-out gasket, leaky drain line, or a faulty sink flange. Other possible sources can be a leaky dishwasher pipe, a loose or damaged discharge pipe, or a loose seal or pipe under your sink. Sometimes the fix is fairly quick and easy, but in other cases, you’ll need the help of a plumber.

What Should I Do if My Garbage Disposal is Leaking?

The first thing you can do is try to identify the problem yourself. Check where in the garbage disposal the leak is coming from — this can usually help you narrow down the root of the issue.

If the garbage disposal is leaking from the top, then the problem could be the sink flange, which can corrode or loosen over time. If it’s leaking from the bottom, then it’s possible the seals on the actual garbage disposal have worn out. Leaks from the side may indicate a loose drain line.

Problems like a loose drain line can often be fixed with a screwdriver, but many of the other problems you run into will call for professional attention.

How Can I Prevent Leaking Problems in the Future?

The easiest way to avoid a future leak is to be extra careful about what goes into your garbage disposal. Try not to put hard waste in the disposal (think chicken bones or fruit pits), not putting too much in the disposal at once, and running cold water while your disposal is turned on. These simple measures can help keep everything running smoothly.
