Three Reasons Why Your Garbage Disposal is Leaking

If you have noticed a puddle of water located under your kitchen sink, the chances of your garbage disposal leaking are high. Like any other plumbing issue, this is not something any homeowner wants to deal with, especially when you don’t know how to fix your leaking garbage disposal. 

Before calling your trusted garbage disposal plumber in Washington DC, check out these causes for a leaking garbage disposal and how you can fix it!

Leaking From The Top 

If you find that the leaking is coming from the top of your garbage disposal, it may not be a problem with your whole unit. The likely cause of this is that your unit has a loose sink flange. A sink flange connects your garbage disposal to your sink drain. 

To stop the leak, you should tighten your mounting bolts and make sure that your plumber’s putty has not been compromised. If it has, you can reseal it with fresh putty.

Leaking From The Bottom

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 come out and fix the internal seals, it would be best to just buy a new garbage disposal unit. A new unit can last 5-10 years and won’t put too much of a dent into your bank account.

Leaking From The Side

When your disposal is leaking from the side, it can be because of loose drain lines. There are two drain lines connected to your system. One is for the dishwasher to drain into the disposal, and the other drains out waste from your disposal to your sewer. These drain pipes are connected by a metal clamp. 

To fix a garbage disposal leaking from the side, make sure you tighten the screws of your metal clamp or replace your rubber gasket. 

How to Prevent Future Leaks

Now that you know how to fix a leaking garbage disposal, here are some tips on how to prevent leakage in the future.

  • 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.

Can’t tell where the leak is coming from? Pour food coloring mixed with water down the drain to find the source of the leaking.
