Your Garbage Disposal is Leaking! What Do You Do?

If left unfixed, a leaking garbage disposal is more than a mess – it can lead to other, bigger problems. Even the most trustworthy garbage disposal can develop the occasional leak. A leak doesn’t always mean replacing the unit, so do a little troubleshooting before rushing to buy a new one.

All garbage disposal units have standard hook-ups: an inlet, an outlet, and a dishwasher inlet. Your unit can leak from any one or all three areas. If the body itself is leaking, you’ll need to replace your disposal, but most other leaks can be easily repaired.

  • Top Leaking Garbage Disposal. The likely culprit here is the flange, which is the part that connects your disposal unit to the sink. The seal often corrodes and loosens over time. To fix, you just need to completely remove the old putty and re-seal the garbage disposal with new putty. This job also requires removing and replacing drain pipes, so if you’re not a DIY-er, it’s a good idea to call in a professional.
  • Bottom Leaking Garbage Disposal. Most bottom leaks are caused by a broken seal inside the disposal. First, make sure the leak is not from higher up and just dripping from the bottom. If it is a broken seal, your best bet is to get a new garbage disposal or make a claim under warranty.
  • Side Leaking Garbage Disposal. It’s not uncommon for garbage disposals to leak where the drain lines connect. There are two connections on a disposal – the smaller hose is for drainage from your dishwasher, and the large pipe farther own is the drain to your sewer. Try tightening or resealing the connections and/or replacing the rubber gasket in the main drain line.

To keep your garbage disposal running smoothly, never put hard food or pour bleach down the drain. It’s also important to perform period inspections of your unit to ensure no leaks are present.
