Debunk a Daunting Task

A working garbage disposal is something we tend to take for granted – until it breaks. If the idea of replacing a broken disposal yourself has you quaking in your boots, rest easy as this task is far easier than you think.
Start Smartly
Before tackling any job that deals with electricity, turn off the power for the device at the breaker box. For the garbage disposal, also shut off the water supply beneath the sink and place a container under the disposal.
It’s also always a good idea to take a photo of your old garbage disposal setup in case you forget where something goes later.
Drain and Disconnect
Remove the two bolts securing the discharge tube on the side of the unit and detach the tube. If your dishwasher drains through the disposal, disconnect this hose, too.
Place an inverted bucket or a small footstool under the disposal to support its weight. Insert the disposal wrench into one of the three small loops surrounding the mounting collar and rotate it counterclockwise until the disposal releases. Now, lay the garbage disposal on its side to easily open the electrical cover plate. Disconnect the wires to fully detach the disposal.
In With the New
If your dishwasher drains through your disposal, insert a Phillips screwdriver into the dishwasher inlet, tap it with a hammer and remove the plug from the disposal. Connect the wiring and replace the electrical cover plate.
Line up the disposal’s mounting collar with the ring assembly under the sink and turn it clockwise using the disposal wrench until the unit is snuggly attached. Reconnect all the pipes, including the dishwasher hose if you have one.
Job Well Done
Towel off the unit and place a dry sheet of paper underneath while running water to check for leaks. Finally, flip the circuit breaker and power back on for one last inspection – and to enjoy a newly-working garbage disposal.
