In every household nowadays, you can find a garbage disposal unit or insinkerator that provides a great addition to any kitchen.  They are designed to chop up or grind down pieces of food and organic material so it can be sent down the drain with a decent stream of water.

However with most kitchen renovation jobs you will need to remove the insinkerator for it to either be replaced or to be used within the new kitchen installation.

Then, you need to turn off the circuit breaker attached to the garbage disposal if the unit is hard-wired to your house. Most of the garbage disposals are plugged into an outlet which is located right under the sink.
  2. After that, place a bucket under the sink trap and also the garbage disposal. Then, choose a Philips-head screwdriver for loosening up the clamp on the dishwasher hose and make sure that it is secured to the garbage disposal. The next step is to pull the dishwasher hose off from the garbage disposal and position the hose out of your sight.
  3. Then, you need to locate the access panel attached to the electrical connections inside the disposal unit if it is hard-wired into your house. The access panel location can either be at the base of the disposal unit or on the side of the unit.
  4. Next, you have to remove the screw that secures the access panel to the garbage disposal unit by using a Phillips-head screwdriver and now the unit has been removed from your sink. The plastic wire caps connecting the house wires with the wires from the garbage disposal need to be un-twist.
  5. You can use a screwdriver to unscrew the ground wire which can be found at the base of the garbage disposal and besides that, you also have to loosen the clamp that holds the conduit to the side of the disposal. The electrical conduit with its wire need to be removed from the disposal unit.
  6. After that, use a pair of channel lock pliers for removing the drain line from the disposal unit and then, you have to loosen the retaining nut until you have slide the nut completely from the garbage disposal.
  7. The next step is to use the blade of a flathead screwdriver for unsnapping the snap ring that you will find locking the garbage disposal unit to your kitchen sink. Then, you need to twist the disposal unit counterclockwise and slowly lowering it down from the sink drain. You can use the Phillips-head screwdriver for removing the three retaining screws that secure the mounting ring to the sink drain.
  8. Then, pull the mounting ring off from the sink drain and tap lightly using a mallet to the bottom of the sink drain flange to loosen it from the sink. After you have done this, you can easily pull the sink flange straight up from the top of the sink. Finally, you can also use a putty knife in order to assist you in breaking the seal of the previous old plumber’s putty.
