Garbage disposal causes the sink to shake or vibrate heavily when running.

Safety first: Turn off the disposal before adjusting anything.

• Run with no load: Turn the unit on with only water running. If vibration is minimal with no food, the issue may be overloading or uneven feeding.
• Check mounting: Tighten the Reginox mounting ring screws and confirm the unit is fully locked into the sink flange.
• Inspect rubber gasket: Look at the rubber mounting gasket between the sink flange and disposal. If it is deteriorated or missing, replace it with a Reginox-compatible gasket.
• Align piping: Ensure the discharge pipe is not forcing the disposal to one side. Adjust pipe length or add support brackets.
