Place the garbage disposal on a wide, clean work surface and locate the rubber gasket. The old gasket should be peeled off, and the new gasket should be mounted in the same spot. Take extra care to make sure that it sits flat and that it pops into the lip. Now you are ready to re-install your garbage disposal. Plug the cord back in reconnect each of the drains to make sure that there are no leaks.

If your disposal grinds poorly, make sure that you are running enough water while operating the unit and that you are not grinding matter that you shouldn’t. If you can hear the garbage disposal running but it is not grinding, the blades may be broken. It’s usually easier and cheaper to just replace the entire unit. See How to Install a Garbage Disposal.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).

Reason Why It May Leak: When the rubber gasket gets old it can develop a leak. Long periods of disuse when there is no water in the drain and garbage disposal can cause the gasket to dry up and leak. If you remove an older garbage disposer for any reason and then put it back it may require a new rubber gasket to get a watertight seal again. Also, if the gasket is not locked evenly on all three sides then it will leak.
Place a 1/2 inch rope of plumber's putty around the drain opening in the sink. Drop the new sink flange into the drain opening and press it into place. Placing a weight, such as a disposal, on top of the sink flange will help hold the sink flange in place while mounting the sink flange to the sink. To avoid scratching your sink or the flange, place a towel between the sink surface and the weight. (See Fig 4)
If there is no item stuck in the blades of the disposal obtain the Allen wrench that should be attached to your disposal or that came with it. There is a breaker socket located on the bottom of most disposal brands. Place the Allen wrench in the breaker socket and turn it back and forth. By doing this you may be able to unlock the source of the problem. Just be certain that the disposal is not turned on when doing this.
From the rich industrialist who wants a clear road into politics or administration to the small shopowner who wants to ask for a reduction of taxes; from the businessman trying to win a contract to a worker looking for a job in a factory; from a professional who wants more clients or greater recognition to somebody looking for an office job; from somebody from the provinces who has come to Naples to buy some goods to somebody who wants to emigrate to America; they all find somebody stepping into their path, and nearly all made use of them.[18]

A high-torque, insulated electric motor, usually rated at 250–750 W (1⁄3–1 hp)[22] for a domestic unit, spins a circular turntable mounted horizontally above it. Induction motors rotate at 1,400–1,800 rpm and have a range of starting torques, depending on the method of starting used. The added weight and size of induction motors may be of concern, depending on the available installation space and construction of the sink bowl. Universal motors, also known as series-wound motors, rotate at higher speeds, have high starting torque, and are usually lighter, but are noisier than induction motors, partially due to the higher speeds and partially because the commutator brushes rub on the slotted commutator.[23][24] Inside the grinding chamber there is a rotating metal turntable onto which the food waste drops. Two swiveling metal impellers mounted on top of the plate near the edge then fling the food waste against the grind ring repeatedly. Sharp cutting edges in the grind ring break down the waste until it is small enough to pass through openings in the ring, whereupon it is flushed down the drain.
Trim the discharge tube as needed. If you’ve upgraded to a larger disposal or one of a different model, there’s a good chance that the discharge tube won’t be the right length to connect to the ground plumbing valve. Fortunately, this is a simple fix—mark the spot on the tube where it should line up with the drain pipe, then cut it to size with a hacksaw. It should be a perfect fit.[19]

Abt carries both types of garbage disposal systems, continuous and batch feed. Continuous feed disposers are turned on and off with a power switch. They usually have a shield surrounding the hole in the sink so things do not come back out while being ground for disposal. Some continuous feed disposals have a reverse setting to help reduce jamming. Batch feed disposals operate when a lid is engaged, making them safer. They are a good option for families with children because food is unable to fly out of the sink. Batch feed food waste disposals are usually more expensive than the continuous feed disposals.
