Disconnecting the Plumbing

  1. Use your basin wrench to loosen and remove the slip nuts connecting the drain pipes to the disposal inlet and outlet. Have your bucket ready to catch any remaining water.
  2. Carefully detach the drain pipes from the disposal. They might be stubborn, so take your time and use gentle but firm pressure.

  2. Secure the disposal using the screws provided.

Reconnecting the Plumbing

Reconnecting the Electrical Wiring

  1. Refer to the picture you took earlier and reconnect the electrical wiring to the disposal terminals, matching the colors and positions.
  2. Secure the wiring connections to prevent accidental disconnections.
  3. Turn the breaker back on, and test the disposal by running some water and then turning on the switch.
