Disposal runs but water leaks from the side discharge elbow connection

Safety first: Turn off power and do not run the disposal while the leak is present.

• Tighten fasteners: Use a screwdriver to snug the two or three screws that secure the discharge elbow to the disposal outlet. Do not overtighten.
• Inspect gasket: If leaking persists, remove the elbow and inspect the gasket. Replace with a new InSinkErator discharge elbow gasket if it is flattened, cracked, or missing.
• Align piping: Reinstall the elbow so that the connected drain piping lines up naturally without forcing the elbow up or down.
• Test for leaks: Run water with the disposal off first, then on, and observe the joint.
