With the garbage disposal shopping, I quickly learned that the big brands are Waste King and Sinkerator and that those were the two best places to start. After going over several models and two trips to two separate best buys (who, by the way, really need to amp up their customer service model) I cheated and had my mom choose one for me. Sue me. So she chose this particular brand, and wow—it works really well, I can’t believe how easy it makes my life. I can put bones, and tough food products down the disposal, and it makes cooking really simple. Go figure.
Modern garbage disposal units connect to dishwasher drainpipes.  This enables dishwashers to expel leftover food scraps and residue that would otherwise accumulate in the dishwasher unit.  A common source of leaks is the area where your dishwasher and garbage disposal connect.  These leaks most often occur when the hose’s clamp is not secure enough and when the dishwasher hose cracks.  To fix this issue, simply replace the cracked section of the hose or tighten the clamp.
Lowe's offers garbage disposals like the InSinkErator Evolution and Badger garbage disposals in various horsepower options. Models with lower horsepower tend to become jammed easily. What if your garbage disposal jams? No problem. Simply locate the hex socket in the center of the underside of the disposal. Grab a hex wrench, put it in the socket, and work it back and forth until you feel the blades loosen up. Once the blades are spinning freely, press the garbage disposal reset button. It's that easy.
If you’re unsuccessful using the wrench, you may need to go in through the drain in an attempt to remove the clog. Disconnect the power to the disposal by unplugging the unit or turning off its circuit breaker, then use long-handled tongs and a flashlight to try to remove the jam.  Never use your hands for this task, even if the disposal is completely disconnected from its power source! Fumbling blindly around a disc of sharp blades is asking for injury.

No need to worry if your garbage disposal is on the fritz—installing a new one is a straightforward project that you can do yourself in just a few minutes. Start by switching off the power to the disposal at your home’s breaker box to ensure that you can work safely. Next, remove the old unit by detaching it from the mounting ring directly beneath the sink drain. Finally, install any necessary new mounting hardware, fit the new disposal into place, and turn on the water to test for leaks before giving it a trial run.

Some types of food remains are not easy to grind in a disposer. Do not put fibrous food items into your disposal. Help grind these items by putting in a few small bones or large ice cubes to the disposal. If the disposer won’t grind it up then turn off the disposer and remove the item with a pair of tongs. When using your disposer, make sure that the disposal is running with good water flow. Good water flow carries the waste down the drain line. Using too little water can create a clogged drain.

To replace a rubber gasket, your first step will be to unplug the cord to the garbage disposal and then disconnect the drain. If you have a dishwasher installed in your kitchen, the dishwasher drain hose will need to be disconnected from the disposer. With the cord and appropriate drain lines removed, you can now grasp the sides of the mounting nut and twist it in a counter clockwise motion, which unlocks the garbage disposal. The waste disposer should then drop right down.
The General Electric 1/3 Horsepower Continuous Feed is a relatively small unit. One of the most important measurements with garbage disposals is the size of the grind chamber. In this case, it’s 26.5 ounces. Power, at 1/3 horsepower, is at the lower end of the scale, but this is a light-duty machine. The owners we surveyed were very happy with the General Electric’s performance.
After using the lowest cost disposers for over 20 years now, I find the newest models have not withstood regular use for more than 5 years. The older models had a blue housing where this next step-up model has a black housing which I am hoping for at least 5 years use. Our oldest (blue housing) disposers have lasted at least 5 years and some are now almost 20 years old.
If the plumber’s putty has failed, you might be able to stop the leak by replacing the putty.  To do so without removing your garbage disposal, loosen the retaining bolts until a gap forms, force the new putty between the pipe and flange, and retighten the bolts to secure the putty into place.  If this does not work, then remove your disposal unit and reseal the flange.  To do this:
Lift the sink flange from the top of the sink. Use a plastic putty knife to scrape off the old plumber’s putty around the top of the flange, then wipe off any putty residue with a damp rag. Grab a palmful of plumber’s putty from the container and roll it into an eighth-inch to quarter-inch-wide “rope” with a length roughly equal to the circumference of the flange. Wrap the rope of putty around the top of the flange like a collar, then insert the flange into the sink drain opening until snug. Re-install the mounting assembly and mounting ring (taking care to securely tighten the mounting bolts on the mounting assembly), then re-attach the garbage disposal, drain pipe, and dishwasher hose in the reverse order you detached them.
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.

Your garbage disposal gasket is the top rim where the rubber seal mounts to the flange.  If your disposer is leaking from this area, the cause could be a leaky gasket.  Gasket leaks can have several causes: ageing gaskets can develop leaks; long periods of disuse can dry the gasket and cause it to leak; if your garbage disposal was removed and then replaced, the gasket may have been improperly sealed; if the gasket is not locked evenly on all three sides, it will leak.
Should your disposal suddenly cease to work, check its overload protection. A red button on the bottom of the disposal trips when the disposal becomes jammed or overloaded to prevent damage and motor burnout. Unplug the disposal, push the button and remove the jam. Some high-end models can sense a jam and will automatically reverse the direction of the blades.
We won’t sugar-coat it. This one is the doozy. If the leak is located at the bottom of the unit that means at least one internal seal has slipped, chipped, or flat-out deteriorated. The catch is, there are lots of these seals inside the disposal, and if one has failed it means the others are on their way. You can replace these seals with expensive, original equipment manufacturer (OEM) parts – or you can just get a new garbage disposal.
I think those are all the important items I wanted to share. The removal of the old one, cleaning the sink hole, and putting in the new box took about 35 minutes start to finish. I wasn't rushing but I was well prepared and had everything ready to go. Plumbers Putty was needed for install. Make sure you have that on hand. There was a thin rubber gasket that went under the flange (between the top flange and a stainless steel sink) that I didn't use because I didn't have a stainless steel sink. The one tricky thing I recall from the directions is that the same procedure is repeated twice in a couple of places - one for using the existing Badger mounting hardware and one for if you are using the EZ Mount system. If you are using the EZ Mount, make sure to SKIP the paragraph that is describing the work as it applies to the Badger mount. That's about it. I had to cut 3/4" off the black waste discharge pipe (90 degree elbow piece that screws into the new disposal) so that everything fit with my old plumbing. I loosened up all the slip joints on the old plumbing so I could wiggle things around as needed, aligned everything, and tightened the plumbing back up. New install was completed in well under 20 minutes after the removal and outlet installation.
We apologize in advanced for stating the obvious, but… garbage disposals absolutely do not last forever! No matter how well it’s made or how much money you spend, any appliance that is exposed to thousands of gallons of running water, dish soap, scraps of food, bones, and the rare (we hope) spoon or lime wedge that accidentally gets dropped into the drain is going to wear out in due time. A unit that’s working well should be able to handle a few scraps of veggies or apple slices in a matter of a couple of seconds. If your garbage disposal seems to take forever to accomplish a simple grinding job, makes a strange noise or emits a nasty smell, it may be time to install a new one.

A sink flange is the uppermost portion of a garbage disposal.  It is the point where the sink, drain, and garbage disposal meet, and it keeps debris from clogging your drain.  If you have a leak at the uppermost area of your garbage disposal, the source is likely your garbage disposal flange.  The two most likely reasons for a flange leak are that the mounting bolts have loosened and that the plumber’s putty has failed.
Read the directions for your model before attempting a home repair. Most disposals have an electrical reset button, and a manual hex key for un-jamming. If the disposal stops working, its internal circuit breaker may have shut it off. Turn the switch definitely off, and try to pull out the hard object that may have jammed it. Then use the right-sized hex key to manually turn the rotor parts (usually directly under the unit in the center). If it turns, then push the reset button. It usually clicks in. Then, turn on the water and try the power, again.
If the disposal is plugged in and doesn’t need to be reset, then you should check the circuit breaker. The breaker could be flipped, which would mean your disposal isn’t getting power. If that’s still not the problem, then either the outlet is dead, the circuit breaker is malfunctioning, or the disposal needs to be replaced. Check the outlet first by plugging something else into it. If the outlet works, try replacing the circuit breaker switch. If that isn’t it either, you have to replace the disposal.
Like most appliances with moving parts, all kinds of stuff can go wrong in your disposal, for all sorts of reasons. Luckily, unlike many appliances, most disposals can be quickly and relatively easily fixed, as long as you’re careful and do your research. The next time you experience one of the following problems, follow these instructions and see if you can’t get things moving again.
Food scraps range from 10% to 20% of household waste,[18] and are a problematic component of municipal waste, creating public health, sanitation and environmental problems at each step, beginning with internal storage and followed by truck-based collection. Burned in waste-to-energy facilities, the high water-content of food scraps means that their heating and burning consumes more energy than it generates; buried in landfills, food scraps decompose and generate methane gas; a greenhouse gas which contributes to climate change.[19]
