How To Install a Garbage Disposal in a Double Sink

The steps outlined here include how to install a garbage disposal with and without a dishwasher. If you have a dishwasher connected to your existing garbage disposal, you will follow the steps outlined below for that. If there is no dishwasher connected, skip those steps.

Turn Off The Power

The first step for any job that you are working on anything that has electricity running to it is to turn off the power at the breaker box. This can be easy if you have a well labeled panel. But if it isn’t labeled very well it might be a guessing game.

Test if the power is off before you make any assumptions. The easiest way to do this is to flip on the switch for the garbage disposal. It is safe to begin if it doesn’t come on. Remember to flip it off though, because you don’t want the new garbage disposal to turn on when you turn the power back on.

This is also the right time to remove any products that are in the way. Find a place to put as many of them as possible. You want to have as much working space as you can. For the installation.

Disconnect The Old Garbage Disposal

There will be two screws attached to the discharge pipe. Back those out all the way and set them aside. If there is a dishwasher attached to the disposal this is a good time to remove the hose that attaches it. To do this turn the screw on the pipe clamp counterclockwise until the clamp is loose. Then pull the connection off the garbage disposal.

There are also three screws facing upward just beneath the sink. Loosen each of these about half way. If you use a screwdriver for two of them, the third should be able to loosen by hand. You want to back them out enough to lift the bottom of the bracket up towards the sink.

Once these screws are loose and the drain pipe is disconnected from the garbage disposal, hold the bracket steady with one hand and twist the garbage disposal to the left with the other. This should pop it loose.

After it is movable, take a flat screwdriver to pop off the metal ring that is holding the pieces of this bracket together. To do this first slide all the parts upwards towards the sink. This will allow the ring to be visible. While holding them up with one hand, use a flat screwdriver in your other hand to slide the ring downward.

Is the garbage disposal plugged into a wall outlet, or is it hardlined in? If it’s plugged in you can simply pull the plug out and the garbage disposal will be free to move. You will need to attach a power cord to the new garbage disposal, and may need to reuse the old cord. Both methods are the same from this point on.

If it is hard lined in, you will need to remove the wires before you can lift the disposal away.

To do this simply turn the disposal upside down, or lay it on it’s side with the bottom facing you (whichever one is easier for you). There is a small metal plate with one screw in it near the location the wires go into the bottom. Remove this screw.

There should be two wire nuts, and one grounding wire screw. Remove the wire nuts, and loosen the screw. Once all three wires are free you should be able to pull them out. You may want to clip them close to the location they were twisted if this is easier.

Disclaimer: Only clip them if you have plenty of length on your wire left. Also only do this if you have a wire stripper handy and are comfortable with stripping the wires later. It can be a larger problem if there isn’t enough length to hook up the new disposal.

You also want to remove the connector the wires are going through. There are a couple of screws that can be removed. Once the wires are pulled out you can turn this connector counterclockwise to remove it.
