Garbage Disposal Leaking from Bottom

Garbage Disposal Leaking From Bottom

There are some reasons your garbage disposal leaks from the bottom, including issues like a broken, deteriorated seal or cracked dishwashing. But the most common cause occurs around a garbage disposal’s bottom reset button. Although some problems are easy to solve, some jobs are better to give to the pros.   

Some Reasons Why Your Garbage Disposal Leaking?

There are several possible reasons behind garbage disposal; in some cases, when the removal installation is new or replaced, you can get an improper connection or fastened insecure.

If your disposal is an older appliance, rusting or cracked plumber’s putty can occur. And a problem like this needs a replacement with fresh putty or, in the worst-case scenario, installing some replacement parts.

Also, the leak could result from extreme struggle to your disposal, significantly when it has sprung up from nowhere.

1. Loose Sink Flange

  • Check the connections
  • Tighten the bolts
  • Reapply plumber’s putty

2. Internal Damage

Internal Damage

When it comes to the bottom of the unit, you will need:

  • Repair or change the internal seals
  • Think about upgrading to a new system

If the source of the leak is coming from the bottom of your garbage disposal, it can be because of internal seals that have worn out over time.

While you can have a professional fix the internal seals, buying a new garbage disposal unit is best.

A new unit can last 5-10 years and won’t affect too much into your bank account.

3. Loose Drain Lines

  • You will deal with the loose drain lines and tighten the metal clamp connections.

Try To discover Where the leak is coming from & Stop It!

Sometimes it is arduous, but you can try drying the entire area with a rag and then run a bit of water to help identify the leak’s origins.

One of the most significant issues is garbage disposal leaking, caused by a poorly sealed or loose flange.

A piece of good advice is to tighten the bolts, and if it doesn’t solve the problem, add fresh putty or replace the rubber gasket to renew the worn or cracked damage if the leak persists.

If the leaking comes from the side, the problem is not with the unit but with the supply lines. In that case, try tightening the metal clamps on the drain line connections and the screws on the drain pipe.

When the disposal leaks from the bottom, the trouble could be a broken or deteriorated seal within the unit that the shell has cracked. When the disposal leaks from the bottom, the problem could be a crushed or spoiled seal that the cover has broken.

Unfortunately, this type of part must an entirely replaced since the issue is rather than just the connections.

Once you finally determine the origin of the leak, then you will only need a possible plumbers putty and an inexpensive replacement part or two.

Remember to turn off the power of the disposal at the breaker before beginning. But if you are a little scared about it, call an expert and top-notch plumbing service. In most cases, your disposal in your modern kitchen convenience should be back up in the glory.

How to Prevent Future Leaks

How to Prevent Future

Now that you know how to fix a leaking garbage disposal, here are some tips on preventing further leakage.

  • Run cold water when using your disposal.
  • Only put soft foods down your sink drain.
  • Regularly inspect your unit for cracks.
  • Check your mounting bolts and connections.

Proper use of a garbage disposal can stave off future leaks. So remember to grind only soft foods; hard items such as bones, apple cores, or raw potatoes can dislodge or damage the internal seals.


If the bottom of the unit is leaking, replace the disposal.

Leaks from the bottom of the garbage disposal (often from the reset button) commonly indicate that at least one seal on the interior shell of the unit that protects the motor has deteriorated or that the body itself has cracked.

These vulnerabilities can cause water from the sink to seep into the shell of the disposal and leak out of the unit’s base.

In old garbage disposal, one compromised internal seal matches by others, so your best bet is to install a new one.

Finally, inspect your disposal for leaks at least twice a year using the dyed-water test to catch and repair minor leaks before they lead to water-damaged sink cabinets or kitchen floors.
