How do you change a garbage disposal?

Answer 1

A new disposal should have instructions with it. Disconnect the electrical supply and the dishwasher tube if it is connected. At the top of the disposal there is a locking ring that attaches it to the sink. There should be 3 tabs sticking out around the ring. They look like 1 inch long tubes. Rotate the ring counter clockwise and the disposal will drop down. Hold the disposal up while turning the ring. The neck sticking down through the sink should have 3 screws holding it in place. Loosen the screws and the plate they go through will raise up so that you can remove the snap ring at the bottom of the tube. With the plate and snap ring removed, push the neck out of the sink. Clean the surface of the sink and use plumbers putty or silicone caulk under the lip of the new disposal neck. Install the neck or flange in the reverse order you took the old one out. Same with the disposal. If there is a dishwasher attached to it, you will need to knock out the plug in the tube on the disposal. Just use a screwdriver and hammer to knock it out before you install the disposal.
