Keep anything too hard out of the disposal. The shredder will dull and become less efficient. Small hard objects can also get stuck and jam the rotating parts. Each garbage disposal has its own capacity for hard objects. The more expensive models of the same brand tend to have higher hardness capacities. The instruction manual usually specifies a list of objects to avoid. You can also gain experience with your own garbage disposal. Strong vegetable fibres can jam some garbage disposals, as well. If something may be harder than what the disposal handles, just put it in your trash can or think about setting up a worm composting bin. Some items to avoid are:
Save yourself a lot of hassle and go with the same brand & model. By doing so you'll avoid having to remount and mess with the drain & sink connections. Save the old power cord so you don't have to buy a new one. You'll need to do some very minimal wiring work to pull the wires from the terminals in the old disposal and attach them to the disposal. Make sure to attach the green grounding wire to avoid getting shocked when you switch on the 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).

Garbage Disposal Replacement


Your garbage disposer is not draining, has water leaks, creates weird noises, or has horrible odors? Troubleshoot your Faulty Disposer. If you are experiencing garbage disposal problems, you will find solutions on our checklist below to help you repair it. Before going out and spending a few hundred dollars on a new one, troubleshoot your existing sink garbage disposer to find the problem.
Next, you’ll connect the wires that you disconnected from the old disposer, to the new disposer. If this isn’t a replacement project, and you’re adding a new disposer where you didn’t have one before, you’ll first need to call an electrician to run the proper wires and a wall switch to the unit. For our project, the electrical wires and switch were already in place.
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.
If the water is leaking at the mounting assembly, make sure it is mounted as designed and not cocked. If the water is leaking at the dishwasher inlet, tighten the hose connector. If the water is leaking through the wall of the container body, your disposer probably need to be replaced. If the water is leaking from adjacent plumbing, tighten the connections as necessary.
IMPORTANT: Whenever you are working on your garbage disposal, inserting items, and/or inserting body parts into your garbage disposal unit, it should be UNPLUGGED and the POWER TO THE GARBAGE DISPOSAL UNIT SHOULD BE OFF!  Failing to do so will put you at risk of SERIOUS INJURY.  Also, if possible avoid placing your hands directly near the blades at the disposal.  If you can, instead use a tool to wedge out items or check the blades for blockage.
Locate the circuit breaker that controls power to the garbage disposal, and flip it to the "off" position before continuing. Fix or replace the main seal if it is leaking. Remove both the drain pipe and the dishwasher hose, if applicable. Insert a screwdriver into the tightening ring and turn it counterclockwise. This will release the garbage disposal unit. Inspect the main seal that sits on the top of the unit. The seal is a large, soft rubber fitting that covers the top edge of the garbage disposal. If dirt, grit or food particles have fouled the main seal, wipe it down with a damp rag and reinstall the disposal unit. If the main seal is cracked, pitted or broken, it needs to be replaced. Once a new main seal has been inserted into the garbage disposal, push it up against the mounting bracket, insert a screwdriver into the tightening ring, and turn it clockwise to lock the unit into place. Reinstall the drain pipe and dishwasher hose, if applicable.
But there is really only one rule you need to follow: Never put your hand or fingers down into the disposal, even if you think the disposal has been unplugged or its circuit has been shut off. If a disposal gets turned on accidentally while your fingers are in the opening, the likelihood is that you will end up with bruised fingers, not bloody amputation. But this is not a risk that is necessary in any way.
Attach the pipes. You will attach a 90-degree disposal drainpipe to the disposal and the tailpiece to the other sink drain. There should be p-traps on both the disposal and the tailpiece from the other sink and they should be level to one another. Use straight pipes and a T-fitting to connect both drains into one line and route the drainpipes into the main drain.
In 2017, in Moscow and St. Petersburg, my research found a substantial increase in grassroots groups oriented around “civic pride” and local volunteer initiatives. These new groups focus on the preservation of green spaces, litter collection, recycling, urban beautification and historic preservation. These efforts represent a new “environmentalism of daily life” more acceptable to the government.

There is a contradiction among some of the brands. InSinkErator’s disposal instruction manual states, “Don’t grind large amounts of egg shells or fibrous materials like corn husks, artichokes, etc, to avoid possible drain blockage.” Whirlpool’s disposal instruction manual states, “designed to dispose of food wastes including bones, fruit and vegetable wastes, pits, egg shells and coffee grounds.”

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.


While inspecting your unit, if you see leaking, you will need to equip yourself with a screwdriver and tighten up the clamp that’s holding the garbage disposal to the dishwasher. The smaller drain line is attached by screws. Tighten up these screws and if the gasket is worn, replace this too (Careful not to overtighten). You should be able to purchase gaskets at your local home improvement store for a fairly inexpensive price.
Warranty - The average industry warranty on a garbage disposal is one year; however, it is not uncommon to see manufacturers’ warranties that can extend up to ten years. As a general rule of thumb, the more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product they have made, but this is not always the case, so it is still important to do your homework.
Turn off the garbage disposal at the breaker box. Remove the drain pipe if it is leaking there. Most attachment clamps are wire clamps with two protruding wires that are pushed together to release the drain pipe. Push the wires together and remove the clamp. Pull the pipe off and inspect the seal for any debris that may have lodged between the seal and the pipe. Wipe the seal with a damp rag to remove any dirt, debris or food particles. Sometimes the wire clamp loses tension. In that case, tighten the hose clamp down in its place, which may secure the pipe leak-free.
In 2008, Italian police arrested three members of the Camorra crime syndicate on September 30, 2008. According to Gianfrancesco Siazzu, commander of the Carabinieri police, the three were captured in small villas on the coast of Naples. All three had been on Italy's 100 top most wanted list. Police seized assets valued at over 100 million euros and also weapons, including two AK-47 assault rifles that may have been used in the shooting of six Africans on September 18, 2008. Police found pistols, Carabinieri uniforms and other outfits that were used to disguise members of the operation. During the same week, a separate operation netted 26 additional suspects in Caserta. All were believed to belong to the powerful Camorra crime syndicate that operates in and around Naples. The suspects were charged with extortion and weapons possession. In some cases, the charges also included murder and robbery. Giuseppina Nappa, the 48-year-old wife of a jailed crime boss, was among those arrested. She is believed to be the Camorra's local paymaster.[46]
Set the garbage disposal down where you can work on and see the rubber gasket. Peel off the old gasket and put the new gasket in the same place making sure that it pops into the lip and sits flat. Now you are ready to set the garbage disposer back in place. Use your knee or a helper to lift the disposal into place while looking down at it from above the sink to verify that the gasket sits flat before locking it back into place. Then look underneath the sink to make sure that all three mounting grooves are locked in. Reconnect the drains and plug the cord back in to test it for leaks.
The size of the motor in the garbage disposal directly correlates to the units grinding ability. Garbage disposals typically have between 1/3-1 horsepower motors. Choose the correct horsepower based on the waste that you need to remove. 1/3 horsepower units will help tackle tasks like grinding vegetables easily, but more power is recommended if disposing a large quantity of food waste such as, vegetables and harder to grind meats.
A garbage disposal unit (also known as a garbage disposal, waste disposal unit, garbage disposer, or in Canadian English a garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The disposal unit shreds food waste into pieces small enough—generally less than 2 mm (0.079 in)—to pass through plumbing.[1]
