Have a Garbage Disposal Leak? Here’s What to Do

A leaking garbage disposal can inconvenience you from time to time. While many homeowners believe that leaking garbage disposal should be immediately replaced – but that’s not necessary. Just remember that a leaking garbage disposal can be easily fixed with just a little troubleshooting and some plumbing supplies.

If you suspect a leak in your garbage disposal, it might be time to look further into the problem. Read on to learn how to repair your leaking garbage disposal leak. 

A Leak from the Gasket

If your garbage disposer is leaking from the gasket, it could be the rubber gasket attached to the top causing the problem.

Rubber gaskets can get old and wear out which usually leads to leaks. If you plan on removing an older garbage disposer and putting it back, the rubber gasket might need to be replaced for a watertight seal. In case the gasket isn’t locked on all sides, the disposer will leak.

But no need to worry, you can easily visit the nearest hardware store to purchase a new rubber gasket and replace it.

A leak from the Flange

Another common reason why garbage disposers leak is because of the disposal flange. The disposal flange goes through the sink and should be properly sealed with putty and tightened. If the flange isn’t tight enough, it might start to leak.

You can reseal the flange by unlocking the garbage disposal and removing the flange and resealing it with a plumber’s putty. Make sure to tighten the screws properly once you push the flange back into its place to secure it.

A Leak from the Side of the Garbage Disposal

If your garbage disposal is leaking from the side, the likely cause is the dishwater drain tube.

The dishwater drain tube can wear out over time and may start to leak. The leaks usually come from the joint where the disposal unit and the line connect. The joint can also wear out or the rubber gasket inside may erode.

You can mitigate this issue by tightening the dishwasher drain line clamp. If that doesn’t work, try replacing the rubber gasket inside and then tightening the clamp.

If your garbage disposal system is still leaking, it might be time to call in the professionals. At Action Craft Experts, we take pride in our comprehensive plumbing services and advanced tools and techniques to resolve all sorts of plumbing problems.
