Garbage disposal causes a loud clunk when starting or stopping

Safety First: Turn OFF the disposal before working under the sink.

• Check mounting ring: Ensure the Waste Maid mounting ring is fully locked and the three mounting lugs are engaged. Tighten mounting screws evenly.
• Inspect rubber mount: Look for cracks or compression in the rubber mounting gasket. Replace if deteriorated.
• Support the sink: For thin sinks, consider adding a support bracket or reinforcing the sink to reduce flex.
• Evaluate internal play: If the clunk persists and you can feel excessive movement when pushing up on the disposal, internal components may be worn. Replacement is recommended.
