InSinkErator garbage disposals, while durable, don't last forever and there may come a time when you have to install a new one. For the unfamiliar, it may be difficult to decide how to remove it, but it's possible. This article will explain how to remove an InSinkErator garbage disposal safely and easily.
Turn off the circuit that delivers power to the garbage disposal before you begin. The circuit should be labeled in your electrical panel. Don't rely on just leaving the switch off, be safe and turn the entire circuit off.
Locate where the electrical feed enters the disposal. It usually enters the side of the unit near the bottom. On the bottom of the disposal, remove the cover to where the electrical connections are made.
Disconnect the black and white wires. Loosen the ground screw to remove the ground wire. Unscrew the lock nut that secures the wire to the garbage disposal and pull the wire out of the unit.
If you have a dishwasher, there will be a dishwasher discharge hose connected to the InSinkErator garbage disposal. This hose enters near the top of the disposal. Loosen the hose clamp and pull the hose away from the disposal. Keep a bucket underneath to catch any water if there is any left in the hose.
Use the tongue-and-groove pliers to loosen the nuts that connect the drain pipe to the garbage disposal.
Support the InSinkErator from below and rotate the three-tab mounting ring at the top, counterclockwise. The garbage disposal will fall free once it is rotated enough.
Loosen the three bolts on the drain assembly and pry off the retaining ring. Then, simply push the drain up and out of the sink and clear away the remaining plumber's putty.
The sink is now ready for a new InSinkErator garbage disposal to be installed, or for a direct drain hook-up.
