In this article I will go over how to properly install a garbage disposal so that it runs efficiently for years to come.

You should consider hiring a professional if you feel uncomfortable performing this type of work or do not have access to all of tools listed below. Hiring out will cost about $75-150 which includes labor and parts (a new unit).

So let’s get started!

Tools needed: Slip-joint pliers   Allen wrench/Hex key    Wire strippers    New food disposer ( you could reuse the old one but I don’t recommend it)    

STEP 1: TURN OFF POWER

Make sure that the power to the unit is off at this point. Your garbage disposal uses electricity so you have to be extra safe. It’s also a good time to clean up any mess created while taking everything apart and making a bit of a mess!

STEP 2: REMOVE FOOD DISPOSER

Most garbage disposers are connected with three large bolts, or three small bolts on most units. Make sure they are tight before trying to remove anything. If your disposal is connected with nuts instead of bolts, use slip-joint pliers to counter-clockwise them. If they are corroded, use a hex key.

Once the nuts have been removed, carefully pull the disposal unit from your sink and put it away for safe keeping.

STEP 3: DETACH PIPE LINES

Most food disposers have water lines attached to them with slip joints or compression fittings that require a special tool to open and close properly. If these need to be detached you will have to cut them off using wire strippers. Cover your ears if there is high pressure in the lines! You can take a metal bucket and place it under the water lines after cutting them off so that any remaining pressure can be released without removing anything further or making mess .
