INPUT ARTICLE: Article: Head to your home's main circuit breaker and find the switch corresponding to the garbage disposal unit. Flip the switch to the "Off" position. You'll now be able to work safely without worrying about accidentally receiving a nasty shock. Garbage disposals are electrical appliances, which means there's a live current running through them at all time while the power is on. Open the doors beneath your sink and take a look directly under the drain. You should see a large cylindrical object situated between the bottom of the drain and the plumbing pipes. This is the actual garbage disposal unit that you'll be replacing. Take note of the make and model of the disposal. Replacing it with a similar model will be as easy as removing the existing unit and screwing on the new one. Locate the pipe extending from the side of the disposal into the ground plumbing. Loosen any nuts or fasteners at the pipe's connection site and give it a firm tug to pull it free. The discharge tube is responsible for carrying ground food waste out of the disposal. Some older garbage disposals are also connected to the dishwasher water supply via a second tube. This one can be disconnected in the same manner. At the top of the unit you should see a thin metal ring with 3 separate lugs, or protruding arms. Take hold of these lugs with one hand and twist the entire ring counterclockwise about 1.5 inches (3.8cm) to dislodge the old unit. Set it aside on a sheet of newspaper or unfolded rag to keep from making a mess. Garbage disposals tend to be surprisingly heavy (some can weigh as much as 15 pounds!), so be ready to catch and hold the unit once it comes away from the mounting ring. It may be a good idea to place a couple paint cans, some wood scraps, or a stack of phone books beneath the disposal to act as a support platform. Turn the unit over and look for the round or square faceplate on the underside. This is the cover for the electrical housing. Unscrew the faceplate and slip the copper ground wire over the green screw. Then, pinch the plastic wire connectors to disconnect the colored wires from the main power supply. A pair of needle-nosed pliers may come in handy for releasing wire connectors that are too small to unclip by hand.

SUMMARY: Turn off the power to the garbage disposal. Identify your garbage disposal. Disconnect the discharge tube. Release the old disposal from the mounting ring. Separate the disposal from the power supply.
