How to Replace a Garbage Disposal?

How to Replace a Garbage Disposal? Now, that’s a question that involves step by step answers. Food waste disposers such as the InSinkErator Badger 5 1/2 HP Food Waste Disposer, Waste King L-2600 Legend Series 1/2 HP Continuous Feed Operation Waste Disposer etc involves specific instructions on how to remove and install them but here are 7 general steps that will do the trick:

Step 1: Prepare for the Mission

Check the instruction sheet that comes along with your new disposer’s package. That’s the first step to a successful garbage disposal replacement. You have to make sure that you have all the parts of the unit written on the sheet with you. Turn off the power to the disposal at the circuit-breaker box. It’s an excellent idea to check the amperage of the circuit to be sure the disposal won’t overload it. The amperage should be seen on the breaker switch.

Step 2: Take Off the Drain Arm and Tube

Disconnect the drain arm from the disposal equipment. You can use pliers to loosen the spring clamp which holds the drain tube for the dishwasher in place. After doing so, remove the dishwasher drain tube from the unit. You’ll soon realize that replacing a garbage disposal can’t be that hard.

Step 3: Take Out the Disposal Unit

The third easy step in replacing a garbage disposal unit is to remove the disposal unit by twisting it off the mounting nut. Remove any remaining water and waste in the unit. Turn the unit upside-down, and remove the plate which covers the electrical connections. Remove the grounding screw and wire nuts, and pull the cable out of the unit. You may also have to loosen a strain relief sleeve.

Take out your old disposer’s drain and mounting assembly. Take also the screws off the mounting ring, and push the drain flange up through the hole in the drain. Scrape off any old plumber’s putty from the sink.

Note: If your new disposer is the same model as the old unit, you won’t need to replace the mounting hardware.

Step 4: Put on the New Hardware

The “How to Replace a Garbage Disposal’s” fourth step is to put a rubber seal on the underside of the drain flange. If your new unit doesn’t come along with a rubber seal, you’ll need to make use of a plumber’s putty. Push the drain flange into place in the drain hole.

Put a second rubber seal on the drain flange on the underside of the sink. Attach the metal backup ring, flat side up. Most disposal equipments have a mounting hardware made of metal, but some units have a plastic hardware. You can take a look at your owner’s manual for specific installation procedures.

Step 5: Attach the Mounting Ring

Attach the mounting ring using three screws in a loose manner. Push the mounting ring in an upward direction, and secure its place with the snap ring. Lastly, tighten the mounting screws that you have attached earlier until the whole assembly is tight and even.

Step 6: Have the New Disposal Ready

If you want your new disposal to be connected to the drain of your dishwasher, use a hammer and screwdriver to take off the knock out plug. Turn the disposal upside-down, and shake it to remove every single thing that might be inside. Take also the electrical plate out, and gently pull the electrical wires away from the equipment.

Attach the strain relief sleeve into place using screws, and push the electrical cable through the sleeve into the disposal. Make sure that the sleeve is tightly placed.

Step 7: Finalize the Installation

Connect the electrical wires, splicing white to white and black to black, then make sure they are firmly connected with the use of wire nuts. Connect the ground wire to the green screw on the disposal, and have the cover plate replaced.

Hang the disposal by twisting it into place on the mounting nut. Rotate the disposal until it is aligned properly, and then attach the drain arm and the drainpipe for the dishwasher. Run water through the disposal for a few minutes for you to make sure that no leaks will occur. Then turn the power back on.

Note: Most disposals that are available in the market may be heavy, so you might want to build a support base to securely hold it up.

Final Say!

Replacing failed garbage disposals can seem daunting at the beginning. You will encounter the usual trepidation about water and electricity, the overly unfamiliar sink connection and enough drain fittings to make leaks a real possibility. There is a very long list of things to consider but great results come from small beginnings. Hopefully, this “How to Replace a Garbage Disposal” article made you realize that nothing is impossible.
