Why Garbage Disposal Leaks?

There are hundreds of reasons for which a garbage disposal unit can leak. You can have a broken pipe, a loose seal, or a broken disposal unit.

Loose seal or screws are easily fixable and need less time and money but if you have a broken disposal unit, that is something to be worried about.

You have to check everything when you find that your garbage disposal is leaking from the bottom. Although you see the unit is leaking from the bottom, it can be leaking from the top or the side.

When the leak is tiny and a very small amount of water can pass through the leak, the water will flow with the external surface of the disposal to the bottom.

It is important to find out the leak before you get into the work. Otherwise, you will end up wasting money and time in the wrong place.

5. Garbage Disposal is Broken or Internally Damaged

This is non-repairable damage. If your unit is leaking from the body where you see some small cracks appearing, this unit is gone. Prepare yourself to buy a new one.

The same thing goes to internal damage. Unless you are covered with a good warranty the unit you are using is ready to be decommissioned.

There are very few instances where you can repair the internal damage to garbage disposal. So, you can try out with the manufacturer or a repair shop.

Garbage Disposal Usage Tips

  1. Do not use a garbage disposal without running cold water into it. Using the unit without cold water will clog the grinder and the pipe ending up costing you a significant amount of money and time.
  2. Go through the user manual of the garbage disposal. There should be some indication of what can be disposed of and what not with the unit you own. Strictly follow the guideline to avoid internal damage.
  3. Never put bleach or chemicals into the garbage disposal unless the manufacturer specifically mentions.
  4. When installing a new garbage disposal, seal all connections carefully so that you do not end up having a leaky garbage disposal.
  5. Not using the garbage disposal for a long period can harm the grinding ability of the disposal. So, run it regularly for a properly functional experience.
