Installing a new garbage disposer to a sink is a matter of attaching the disposer to a mounting ring at the bottom of the drain flange and hooking the unit up to the drain pipes. Most new garbage disposers come with the power cord attached so it can be plugged into the electrical outlet when the installation is complete. Installing the garbage disposer is a job that can be done in about an hour or two.
Things You'll Need
- Plumbers putty
- Damp sponge
Turn off the power at the breaker box for the electrical source that you will plug the new garbage disposer into before installing the disposer. Form a rope of plumbers putty, rolling it out by hand and lay it out around the underside of the drain flange lip.
Press the drain flange down onto the drain hole so the putty forms a seal between the flange and the hole. Attach the backup ring and fiber gasket to the flange from underneath the sink and place the mounting ring around the flange from under the sink.
Secure the mounting ring to the flange with a screwdriver, tightening the mounting ring screws so the flange is flush to the top of the sink. Clean any excess plumbers putty away from the top of the drain flange with a damp sponge.
Attach the disposer to the mounting ring with the drain outlet facing the drain pipe. Secure the disposer to the mounting ring by turning the lower ring clockwise to lock it in place.
Fasten the drain pipe to the drain outlet on the garbage disposer and tighten the mounting nut on the mounting ring with a screwdriver. Secure the slip nuts on the mounting ring with pliers and plug the power cord of the disposer into the electrical outlet.
Flip the breaker switch on at the breaker box to restore power to the garbage disposer.
Tips & Warnings
- To prevent injury, always shut off the power to the garbage disposal at the breaker box before installing the unit.
