How to diagnose a problem with a garbage disposal-This article deals with leaking underneath the disposal. This information is specifically for existing disposals, not new installations.
- Place a sink stopper in the sink and fill the sink with water.
- Wrap paper towels directly at the very top of the garbage disposal around the sink flange.
- Wrap paper towels around the drain discharge elbow on the side of the garbage disposal where it connects to the garbage disposer.
- Wrap paper towels around the dishwasher connector on the side of the garbage disposal where it connects to the dishwasher.
- Once you have wrapped all the necessary places, release the stopper and let the water drain.
- Check all of the paper towels to see if they are wet. If any are wet, the leak is coming from that area and is caused by an issue with the installation of that specific item.
