Turn off power to the InSinkErator 444 by switching off the dedicated breaker in the main breaker panel. Attempt to turn on the Badger 444 to confirm the power is off.
Disconnect the electrical wires from the InSinkErator by removing the bottom plate and unscrewing the wire clamps with a screwdriver. Unfasten the ground, the positive and negative wire from the Badger by turning the lock nut free with pliers and push the wires aside.
Place a bucket directly under the InSinkErator. Disconnect the discharge hose connected to the dishwasher with pliers if applicable. Allow the hose to drain into the bucket.
Turn the mounting ring located at the top of the InSinkErator counterclockwise until is becomes unattached. Keep one hand under the Badger 444 to support its weight once the mounting ring comes loose.
Unfasten the retaining ring's assembly bolts with pliers. Then pry off the retaining ring with a screwdriver. You may now run the drain directly to the sink or install a new waste disposal unit.
