Garbage disposal removal is an important step if you would like to replace your garbage disposal with a new one. As you might already know, a garbage disposal needs replacement if you use it often for many years. Removal should be done as soon as possible when you find that the motor is worn out and the blades are not as sharp as before.

Keep in mind that if the blades are not sharp, they will allow large pieces of food waste to fall down the drain and clog your pipes. They can also damage your drain system and you will have to pay a lot of money to fix it.

Step 1 - Shutting Down the Power and Water Supplies

Always remember to shut down the power before you try to remove your garbage disposal. You need to do this by turning off the home circuit that provides electric power to the kitchen. Keep a flashlight with you because the lights of your kitchen may be turned off as well when you turn off the circuit. Remember to shut down the water supply, too. This must be done in order to prevent flooding in your kitchen area.

Step 2 - Removing the Plumbing

The garbage disposal is usually connected to the drainpipe from the bottom. Remove the pipe by unscrewing it. Pull it down by about 2 inches and then push it aside. If you have a dishwasher attached to the drainpipe of your kitchen, disconnect the clamp that attaches the 2 drainpipes to each other by using a flathead screwdriver. Now it is time to disconnect the main plumbing unit and remove it from its place.

Step 3 - Taking Away the Garbage Disposal

Find the principal connection in the shape of a large coupler that is gray in color and is connected to the kitchen sink from the bottom. Use a screwdriver to remove this connection. If you see that the coupler cannot move, it is probably stuck. You can solve the problem by using a rubber mallet to strike the coupler lightly. Take away the coupler from its place and remove the garbage disposal by sliding it down.

Now it is time to remove the wiring from the garbage disposal. But before you start removing the wiring, go check the power supply again and confirm that it is turned off. Remove the wiring panel from the bottom of the garbage disposal by using a flathead screwdriver.

The color of the wires may vary from red to yellow, it depends on what type of garbage disposal you have. Turn the connectors gently to remove the wires so the garbage disposal can be removed completely from the area.

Keep in mind that the main function of a garbage disposal is to chop discarded food into small pieces, but they should be of a small size that allows them to pass easily through your pipes. The system of a garbage disposal runs on electrical power and its use is quite common in households throughout North America. It is alternatively known as a food waste disposal, garbage disposer or even as a garburator, especially in Canada.
