Disposal is unusually loud compared to when it was new, even with similar loads.

Safety first: Turn off power before touching the unit.

• Check mounting and gaskets: Tighten mounting screws and replace worn McAlpine rubber gaskets or sound baffles.
• Inspect for contact points: Ensure the disposal body is not touching cabinet walls or rigid pipes that can transmit noise.
• Evaluate age: If the unit is many years old and noise has gradually increased, internal wear may justify replacement.
