Garbage Disposal Not Working? Your Pipes May Be the Problem

Your garbage disposal uses several parts and pipes to make those bits and pieces go away, and sometimes these pipes wear out and cause leaks. The first step is to check for any leaking pipes under your sink to confirm the problem.

Check Your Drain Line Connections

The weakest point in any piping system is where the pipes connect, and in most cases, that’s where you'll find the leak. There are several ways to check for a leaking pipe; when you find one, it’s time to call for a replacement.

How to check your drain line connections

  • Dry off all the piping under your kitchen sink so it's easier to identify any new water leaks. Run the tap and keep a watchful eye on the pipes. After a few minutes, if the drain lines are leaking, you may see fresh water on the pipes.

  • If you didn't see any new leaks, put the plug in the sink and fill it up with water. Let the water go down all at once and watch for leaks.

  • If you still don't see any leaks, try turning on the garbage disposal while the tap is running. Once again, watch for new leaks.

  • If both the sink and garbage disposal drain lines aren't the source of the leak, try running the dishwasher (if you have one). Watch for leaks while the dishwasher is running.

If faulty drain lines aren't the issue, you can consider a few other causes of garbage disposal leaks.

What To Do If Your Drain Line Connections Are Faulty

You’ll want to bring in a certified plumber to replace the leaking section of piping under your sink. Without working drain lines, your garbage disposal can't work its magic.
