How to Find the Source of a Garbage Disposal Leak


Where is all that water coming from? Homeowners are usually startled when they reach under the sink to grab something and find everything drenched in water. It’s often difficult to find the source of water leaks. The main consideration that gets overlooked is a possible garbage disposal leak. The following details will help you determine if the garbage disposal is the source of the leak in your house.

Common Areas Garbage Disposal Leaks Occur

  • Drain Pipe – The drain pipe is metal or plastic. It is responsible for draining food and water away to the sewer.
  • Dishwasher Connection – The connection is a rubber hose that connects to the side of the garbage disposal.
  • Sink Flange – The term “sink flange” might sound complex. However, it is quite simple and connects the top of the disposal to the bottom of the sink drain.

Locating the Source of the Leak

  • Run the water – Run the water from the faucet and look underneath the sink to see if you can find the source of the leak. Usually, you can observe water leaking from parts of the disposal, the drain pipe or the dishwasher hose.
  • Test the Sink Flange – Dry the sink flange and the outside of the garbage disposal. Next, put a water stopper or plug in the sink drain and fill the sink with water. Several inches of water should be good enough. Allow the water to sit in the sink for a few minutes. Then, check if there is any sign of water dripping from the sink flange. If it’s dry, you can feel confident that the sink flange is not the source of the water leak.

If you have located the leak it is best to mark it with a piece of tape for easy locating later. Many homeowners enjoy doing DIY projects such as fixing water leaks in their kitchen. If you are familiar with fixing leaks it might be an easy task to complete. However, if you are not comfortable about fixing plumbing issues in your home, you should contact a professional immediately.

Remember it’s better to be safe than sorry. Conducting a DIY plumbing project can cause more harm than good if you don’t know what you are doing. It is always best to hire a plumber for further assistance. They will confirm the source of the leak as well as provide options to fix it.
