If you're replacing a commercial garbage disposal, then you'll either want the Drain Strainer with Crown Adapter or the Drain Strainer XL. Both of these models have a universal Crown Adapter on top that serves as a funnel to cover the hole once the commercial garbage disposal has been removed. Note that it doesn't actually attach to the sink bowl, but you'll adjust the legs to get your unit flush underneath the bottom of the sink.

Some higher-end units have an automatic reversing jam clearing feature. By using a slightly more-complicated centrifugal starting switch, the split-phase motor rotates in the opposite direction from the previous run each time it is started. This can clear minor jams, but is claimed to be unnecessary by some manufacturers: Since the early sixties, many disposal units have utilized swivel impellers which make reversing unnecessary.[26]


InSinkErator garbage disposals provide a convenient and environmentally-conscious alternative to sending leftovers to landfills. Capable wastewater treatment plants can even recycle food scraps into energy and fertilizer. Plus, using garbage disposals can significantly reduce the amount of trash sent to landfills and reduce greenhouse gas emissions.


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.
If the leak occurred under the sink and at the top of the disposal before you unplugged the sink drain, your leak is in the sink flange. This indicates that an improper seal exists between the unit and the sink, which can occur from corrosion or the disposal being bumped hard and out of place. This fix requires you to move the disposal altogether. Then apply a generous amount of plumber’s putty to the flange. Finally, replace the disposal and retighten the flange.
The snap ring fits into a groove on the lower end of the sink flange. When you’re working under the sink, it prevents the upper mounting bracket from falling off. Removing an old snap ring can be frustrating-unless you know this trick: Starting at the break in the ring, insert a thin-blade screwdriver between the ring and the flange. Pull down on the ring with the screwdriver’s blade and walk the blade around the ring. The ring will pop right off.
Even though a leaking garbage disposal is a fairly simple fix, there can be a few factors that can complicate the process somewhat. For example, there are a few different places within the connection system that may spring a leak, so often the hardest part of fixing a leaking garbage disposal is trying to determine where the leak is coming from.Aside from the obvious connections, possible areas for leaks include water inlets and outlets as well as rings and seals.

Ensure the breaker that controls the garbage disposal is off. Inspect the inlet hose from the dishwasher. If the leak is coming from a crack in the fixture itself, the unit needs to be replaced. If the hose has cracked or frayed, unscrew the clamp and remove it from the disposal unit. Cut off the end of the hose with a utility knife up to the point where the leak began. Dishwasher hoses provide plenty of slack, so cutting off a few inches should not be a problem. Slide the hose back onto the fixture, and reinstall the clamp.

If the source is not a connection from above then your disposal needs to be replaced. Try cupping your hands around the very top under the sink while running water. The ring that seals the gasket turns clockwise to tighten. The only other repairable leak would be where the piping comes out the side. There can also be a smaller dishwasher drain hose above that.
Here are some problems that every garbage disposal can run into, old or new. Learning about your garbage disposal and how it works (and how it doesn’t work, of course!) is the first step to decide if it simply needs a repair or if it needs to be replaced all together. One thing that stands for any and all situations: never stick your hands down the drain!

Hang the disposal by aligning the three mounting tabs with the slide-up ramps on the mounting ring. Holding the disposal in place, turn the lower mounting ring until all three tabs are locked into the mounting assembly. The disposal will now hang by itself. Tighten the three mounting screws, ultimately tightening each screw a few turns at a time until the mounting assembly is evenly and tightly seated against the bottom of the sink.
In 1977, brothers Bob and Jim Gregory founded Texas Disposal Systems, Inc. with $10,000, one customer, one truck and plenty of determination. Building on a deep commitment to customer satisfaction and environmental preservation, the Gregory Family created a collection of businesses that has become one of the largest independently-owned solid waste collection and disposal companies in central Texas.
Discharge Pipe: The discharge pipe that goes into the drain of the sink is attached to the bottom of the garbage disposal. Either of these parts can sometimes loosen from regular use or may fail altogether with enough wear and tear.Check to be sure the connection is tight and tighten with a plumber’s wrench if necessary. If the discharge pipe still leaks, the seal that is located between the retaining nut and the discharge pipe may need to be replaced.
Some other kinds of garbage disposal units are powered by water pressure, rather than electricity. Instead of the turntable and grind ring described above, this alternative design has a water-powered unit with an oscillating piston with blades attached to chop the waste into fine pieces.[27] Because of this cutting action, they can handle fibrous waste. Water-powered units take longer than electric ones for a given amount of waste and need fairly high water pressure to function properly.[citation needed]
Did exactly what I expected to. We bought a house with an older disposal and the gasket/rubber that blocks things from falling down into the disposal was cut away. I replaced and is like new. It makes the disposal sound much better too. A couple things about removing disposal and installing gasket...1) use a large Allen key (short end) to stick in the eyelet to unlock the disposal. 2) the gasket fits over the mouth of the disposal and locks into place. Don't just stick the new gasket in up from the bottom hole like I did. 3) use channel locks to tighten the last bit of the disposal/sink collar by pinching the eyelet and collar screw mount. Enjoy!

Proper use of a garbage disposal can stave off future leaks. So remember to grind only soft foods; hard items such as bones, apple cores, or raw potatoes can dislodge or damage the internal seals. Run cold water through the sink drain before and after food disposal to keep solid fats from congealing into gunk (which can deteriorate the sink flange and cause leaks). Finally, inspect your disposal for leaks—at least twice a year using the dyed-water test—to catch and repair minor leaks before they lead to water-damaged sink cabinets or kitchen floors.
As a general rule of thumb, the heavier and bigger that a garbage disposal is, the more quietly it will operate – so long as it fits properly underneath your sink. Even though the sound dampening technology used in the design of garbage disposals has improved dramatically in the last 10 years, it is unrealistic to expect your garbage disposal to operate noise free. Under specific sinks, some disposals will be noisier than others due to the amount of vibration they produce. Ideally, you should look for a garbage disposal that features a nylon, insulated grinding chamber, like those produced by WasteKing.
If the garbage disposal won’t turn on, then it’s probably not getting power. First, make sure it’s plugged in. It’s easy to forget that disposals have wall outlets. It’s easy to knock a plug out of an outlet accidentally, especially in a dark place like under the sink. If the disposal is plugged in, check the reset button on the bottom of the disposal unit. If the disposal requires resetting, the button will be popped out. Simply press it and try the disposal again.
Installing a garbage disposal involves tapping into your home’s plumbing and electrical systems, and both systems need to be handled correctly to safely install your garbage disposal. Someone with a lot of experience can handle the job in 2 or 3 hours—or maybe even less. Attempting a garbage disposal installation without any training will likely take at least double the time required for a professional to install the garbage disposal.
