How to Fix a Leaking Garbage Disposal

This guide provides steps to diagnose and repair a leaking food waste disposer.

Common Leak Locations

Leaks can occur from several areas on a garbage disposal. Identifying the source is the first step.

• The sink flange connection at the top.
• The dishwasher inlet connection.
• The drain pipe connections.
• The main housing or reset button area.

Diagnostic Steps

1. Check the Sink Flange

Water leaking from directly under the sink bowl often indicates a failed seal at the sink flange. Tightening the mounting bolts or replacing the plumber's putty may be necessary.

2. Inspect Inlet Connections

Check the hose connection from the dishwasher and the side inlet for loose fittings or cracks.

3. Examine Drain Pipes

Ensure the pipes connecting to the disposal outlet are properly aligned and sealed. A loose slip nut can cause a leak.

4. Identify Housing Leaks

Water coming from the bottom of the unit or the reset button area typically means the internal seals have failed, requiring unit replacement.

Repair Procedures

Once the leak source is identified, follow the appropriate repair method.

Resealing the Sink Flange

Disconnect the disposal, remove it from the mounting assembly, clean the old putty, apply new plumber's putty, and reassemble.

Tightening or Replacing Connections

Tighten loose hose clamps or drain pipe slip nuts. Replace any cracked hoses or fittings.

Replacing the Disposal Unit

If the housing is leaking, the disposal must be replaced. Ensure the power is off, disconnect plumbing and wiring, and install the new unit.

Safety Precautions

• Always disconnect power at the circuit breaker before starting any work.
• Never place hands inside the disposal chamber.
• Use tools appropriate for the task.
