Your old discharge tube probably won’t be the right length for your new disposal. If it’s too long, simply connect it to the disposal, mark it and cut it with a hacksaw for your garbage disposal installation. (Loosen the other pipe connections, if necessary, to insert the tube back into the tee.) If the old discharge tube is too short, you may have to make a time-wasting trip to the store. To avoid this, make sure the new garbage disposal installation kit includes a tube, or buy one separately at the same time for about $3.

4. Is installing a garbage disposal worth the additional water expense? On average, a modern faucet runs 2.5 gallons of water per minute, or 900 gallons per year based upon the average annual household usage in the U.S. Depending on how often you use your disposerl, your home’s water usage, and water bill, will rise. This is one factor you’ll need to consider before deciding whether or not to buy a garbage disposal.
As advertised, it does come with a corded plug so it will need an outlet. My old Badger was a direct wire. Some folks tore out the cord and the strain relief as a fix and hard wired it like their old one. Some folks put an outlet in, which I found that to be a 15 minute job. I didn't want to mess around with chopping out the stock cord and putting in a new one and messing with the strain relief replacement. I thought the new outlet process was much easier because, heck, the wire's already there and that's always the hardest part of wiring a box! I shoved some of the extra length of the existing wire back into the hole in the wall that it came out from. I thought carefully about where the new box should go so the body of the disposal didn't hit it. I screwed it to the back of the cabinet, poked the wires into the box, screwed them to a new receptacle and, voila!. NOTE: IF YOU DON'T KNOW WHAT YOU'RE DOING WITH ELECTRICAL WIRING, DO NOT ATTEMPT THIS YOURSELF. If you do, be sure to kill the power at the circuit breaker and it is probably the easiest box you will install. Just make sure it is securely mounted into something besides the flimsy back panel of the cabinet.

You should first find out whether only the disposal is broken, or if the power has gone out completely in the areas near your kitchen sink. Try resetting the circuit breaker that leads to the kitchen, or replacing a fuse if you have an older electrical box. If the garbage disposal makes no noises at all when you flip the switch, you might also want to check under the sink to see that it’s plugged in.

A: A leaking garbage disposal often goes unnoticed until you confront a sopping cabinet, a foul-smelling puddle, or an audible drip-drip-drip from the unit. The fix can be frustrating, too, because the leak can stem from a number of components in the system. Fortunately, with a little sleuthing, you can zero in on the leak and—depending on the exact location—stop the icky oozing and repair the component that caused it. Worst case scenario, if it turns out that the garbage disposal must be replaced, installing a new one is a reasonable do-it-yourself task for those with basic plumbing skills. Read on to keep the cash you’d otherwise hand over to a pro.
See The Drain Strainer™ with Crown Adapter installation instructions and dimensions (or the XL installation instructions and dimensions below for taller sinks) below to see the actual dimensions for each model. The legs can adjust up to an additional 5 inches and you can add as many sets of 6 inch leg extensions as needed to achieve the proper total height.
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.
Because it’s out of sight, it can be easy for some homeowners to forget they even have a garbage disposal — especially if it was installed by a  previous owner. However, an unused unit can rust and seize up, which can lead to leaks and mechanical problems. Make a habit of running your disposal for a minute or so every couple of weeks, even if you don’t actually grind anything.
Your electrical supply wires should include a black (or hot) wire, a white (or neutral) wire and either a green or a bare wire, which is the ground wire. First remove the electrical cover plate on the bottom of the new disposer. Then move the new disposer into the cabinet. Screw the threaded end of the cable connector into the round hole on the bottom of the disposer. You’ll run your electrical supply wires through the cable connector and up through the access hole.
Waste disposal units may jam, but can usually be cleared either by forcing the turntable round from above or by turning the motor using a hex-key wrench inserted into the motor shaft from below.[25] Especially hard objects accidentally or deliberately introduced, such as metal cutlery, can damage the waste disposal unit and become damaged themselves, although recent advances, such as swivel impellers, have been made to minimize such damage.[citation needed] More problematic are drain blockages caused by shredded waste that is fibrous, e.g., artichoke leaves, or starchy, e.g., potato peelings.
If the disposal’s still leaking, loosen the mounting bolts and push the sink flange up until it’s slightly higher than the surface of the sink. Apply fresh plumber’s putty to the threshold between the flange and the sink. When you’ve applied enough, re-attach the unit by putting the bolts back and tightening. Wipe away excess putty that squeezed out. Finish re-installing by replacing the disposal unit on the mount. Turn the disposal back on and look for leaks.
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.
In most cases if your garbage disposal is humming it is because a foreign object is stuck in the disposal. If an item has been jammed in the blades of the disposal they will be unable to rotate. This can result in a humming noise. If this is the case simply unplug the disposal under the sink then survey the drain hole. If you discover that an object is stuck in the blades remove it. Once you have done this you can plug the disposal back in and flip the switch. This should clear up the problem.
If you misplaced your wrench that came with the unit, don’t worry. The store you got your unit from should have replacements for as little as $3 to $5. An Allen wrench will usually work well, too. Replacing the motor is the most costly repair for a disposal, so replacing the unit may be your best bet. If the disposal is jammed and won’t budge after using your wrench, turn it off and call us right away.

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.
Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
You can buy a 1/3-hp disposal for $80 or less, but our experts suggest that a more expensive unit with at least 3/4 hp would be a better choice. The more powerful the motor, the less chance it will jam. In addition, higher-priced disposals are generally quieter and have longer warranties. If you need to replace the splash guard guard as part of your garbage disposal installation, take a look at this guide.
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.
