    Leaks are a problem wherever they occur. If you notice excess water underneath your kitchen sink, it’s possible you have a leak in your garbage disposal. Sometimes repairing a leak can be an easy fix, while other times it can require professional help. In this post, we’ll cover ways to spot a garbage disposal leak, identify the source, determine the cause, and offer solutions.


    There are four common parts of a garbage disposal that can leak:

    • The sink flange, which connects the disposal to the sink;
    • The dishwasher hose connection, a plastic hose that connects the side of the disposal to the dishwasher;
    • The drain line connection, usually a curving metal or PVC pipe connecting to the main drain pipe; or
    • The reset button, underneath the primary disposal unit.


    As mentioned, there are a handful of obvious signs that there’s a problem with your garbage disposal. Things like puddling water, dripping, dampness, or even a musty smell. If you’ve confirmed that the leak isn’t coming from the sink itself or the P-trap, it’s likely the garbage disposal. 

    To figure out exactly where it’s coming from follow these simple steps:

    1. Turn off and unplug the disposal.
    2. Fill up the sink about halfway with water.
    3. Add a few drops of food coloring.
    4. Look for leaks in the four locations listed above. The food coloring should help you see any spots!


    So you figured out where the leak is coming from, but what’s causing it? For the sink flange, dishwasher hose, and drain line, it’s likely a simple plumbing fix. That means common things such as bolts, screws, or other sealants have become loose or started to wear. A few twists of a wrench or some fresh sealant should do the trick. If the leak is coming from the reset button, that’s a sure sign of age and the entire thing needs to be replaced.
