When you buy a new disposal, the box will contain all the parts you need to install it. Before you jump into removing the old unit, take a few moments to familiarize yourself with all these parts. Put them together in the correct order and try out the locking mechanism. Understanding how everything fits together ahead of time will make the job a cinch.
Loosen the nut securing the rest of the assembly. Just below the sink flange where the drain empties into the garbage disposal you’ll see a circular plastic piece similar in appearance to the mounting ring. Insert the tip of a screwdriver into one of the lugs on this piece and rotate it in a counterclockwise direction. Pull the nut away and set it aside.[9]
You’ll need to measure the new discharge tube to make sure it fits into the existing drain assembly. In our installation, the garbage disposer doesn’t use the discharge tube, but connects directly to the drain. If this isn’t a replacement project, you’ll need to tie in a drain assembly to the existing sink drain, which might take reconfiguring the drain. Be sure to reach the manufacturer’s instructions, and check out our Frequently Asked Questions section on this site for more information on how to do this, or visit your local independent home improvement retailer for the products and advice you’ll need for this step of the project.
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.

Modern food waste disposers are often connected to your dishwasher’s drain pipe. This connection enables your dishwasher to rid itself of any leftover food scraps or residue that it might accumulate while washing your dishes. Where the dishwasher hose and the garbage disposal connect is a common source for leaks. The leaks most often occur when hose’s clamp is not secure enough. Leaks also develop when the dishwasher hose cracks. In order to fix this type of leak, you should either replace the cracked section of hose or tighten the clamp down.


There are many potential causes for a leaky garbage disposal.  Luckily, identifying the cause of your garbage disposal’s leak is as simple as observing the source of the leak, and repairing the issue yourself is very doable.  Most often, if your garbage disposal is leaking, the cause can be identified and repaired yourself in short time, saving you the cost and hassle of replacing your entire disposal unit.
Use a wet-dry vacuum cleaner to remove any smaller shards of glass. Simply hold the opening of the hose over the top of the garbage disposal and allow the vacuum to run until you can't hear anything be sucked up anymore. If the sink isn't particularly wet, you can use a regular vacuum, covering the end of the extension tube with a nylon stocking secured with a rubber band.

Most modern kitchen sink drains are this dimension--both on the garbage disposal side and the "rinse" side. These are well made items that work very effectively. Unlike most kitchen sink stoppers that rest on top of the drain opening and extend upwards into the sink when you're doing dishes, these fit down into the large opening and seal the smaller opening above the garbage disposal or "rinse" sink drain strainer. In other words they seal the drain without extending upwards into the sink full of water.


Garbage disposals are considered nearly essential for modern kitchens. Installed underneath the sink, they grind up food into particles that will easily flush down a drain. A common problem with garbage disposals is that they will become jammed if too much food is pushed into them or a foreign object falls inside. When jammed, the circuit breaker may trip, cutting the power to the unit. When that happens, it will appear that the garbage disposal motor has burned out even though that may not be the case.

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.

Run your garbage disposal for longer each time you use it. A mistake many people make is turning off their garbage disposal as soon as the grinding noises stop. It is better to leave the garbage disposal on (with the water running) for several seconds after the grinding noises subside, as there may still be small particles in the disposal unit which have not yet been cleared away.
Some jams you can free and get the motor to spin and sound like it is working, but the blades are stuck in one position and can’t spin freely to do their job properly. This is very common problem – the motor works so we think everything is working. Not the case! This can lead to stoppages, food trapped in the disposal and a bad smell. These blades can’t be repaired. The disposal needs to be replaced.
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.
InSinkErator is a brand name that is well-known for their design and manufacturing of waste disposal systems and instant hot water dispensers. John Hammes founded the company in 1927 in Racine, Wisconsin, where their headquarters remain today. Hammes is credited with designing and producing the first “in sink” waste disposal system, and the InSinkErator is a play on the word “incinerator”. Currently, InSinkErator produces and markets garbage disposal systems under the Evolution and Badger Series brand names.
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.

There are two main types of garbage disposers—continuous feed and batch feed. Continuous feed models are used by feeding in waste after being started and are more common. Batch feed units are used by placing waste inside the unit before being started. These types of units are started by placing a specially designed cover over the opening. Some covers manipulate a mechanical switch while others allow magnets in the cover to align with magnets in the unit. Small slits in the cover allow water to flow through. Batch feed models are considered safer, since the top of the disposal is covered during operation, preventing foreign objects from falling in.

To reseal the leaky flange, you must first detach the garbage disposal. Start by loosening the screws securing the main drain pipe to the disposal, then loosen the screws in the metal clamp securing the dishwasher hose to the disposal and detach the drain pipe and dishwasher hose from the disposal. Loosen the screws in the mounting ring that connects the disposal to the metal mounting assembly beneath the sink, then pull down the disposal and carefully set it on a clean, dry surface. Loosen the bolts in the mounting assembly with a wrench, then pull down the mounting assembly and set it near the disposal.
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.
