Working our way down from the top, we have the stopper. This is the visible portion of the garbage disposal that opens and closes to allow waste in. The flange underneath is where the food waste will pass through. Connected to this is the hopper. This is the part of the disposal which pushes food down into the shredder. The hopper helps stop unwanted waste from getting into the shredder and damaging it. Below that there is a clamping ring which attaches the shredder.
This is where the waste is churned up by sharp blades and reduced into smaller parts that can pass through the system.
If the shredder becomes damaged, you may need to consider replacing the entire device as it's essential for the process. Underneath this, you have the impeller which moves the water through the system. This helps push out the waste into your plumbing now it's been reduced into smaller parts. The diagram shows how the different parts fit together. The real question is, can I install my garbage disposal myself? Well, the answer will vary from person to person.
It's not overly complicated, and the plumbing is relatively basic, so if you have some experience with home improvements you can almost certainly do it yourself. Installing your disposal yourself has some benefits. Firstly, it's free, providing you have all the tools needed to complete the installation. You can also save a lot of time because some plumbers have long waiting lists to do house calls.
Garbage disposals will usually come with a full installation guide, but if you don't feel comfortable doing it or you run into trouble, then you should get a professional plumber to help. It's also worth checking the warranty because some will be voided if the installation isn't done correctly.
Installing a garbage disposal isn't overly challenging, but you should ensure you're taking all the precautions to do it safely. Before you even think about the installation, you should consider what kind of garbage disposal you need in your home. There's a lot of choices out there, but you should make sure you're getting one that's the right size and shape to fit into your existing setup.
Once you've selected your model, you need to ensure you have all the tools required for installation. You should have a hammer and hacksaw handy to help connect the pipes, and you should also make sure you have a Phillips screwdriver.

Rotate the garbage disposal so that the discharge tube is aligned with the drain trap. If the discharge tube is too long, cut off as much as necessary. If it is too short, you can purchase an extension.

Use a noncontact voltage tester to ensure no electricity is leaking from the wires inside the box. Adjust the sensitivity of the voltage tester to respond only when it touches or nearly touches the junction box. Hold the tip of the pen against the junction box.
There will be a drain pipe extending from the side of the garbage disposal to the drain on the adjacent sink. It will be secured with slotted screws.
Use a flat-head screwdriver to remove it from the disposal. If you have a dishwasher, you will need to detach a dishwasher hose from the disposal. A snap ring secures the garbage disposal to the mounting bracket. Slide a flat-head screwdriver under the snap ring to pry it open and off the flange.
Use caution as the garbage disposal comes loose. It will be heavy. You might want to place clean rags or towels below the dishwasher to protect the floor.
Once the disposal is out of the way, remove the mounting bracket. It will be attached by three Phillips-head screws. Unscrew it from the bottom of the sink. Use a pipe wrench to carefully loosen then remove the nut securing the drain flange. You will then be able to push the sink drain portion up through the sink for removal. Use a putty knife to clean up the plumbers putty from around the drain hole. You may need to use a razor blade for stubborn bits.

If necessary, trim with a fine-tooth hacksaw. Attach the elbow fitting to the tail pipe. Measure the distance between the end of the elbow and the T-fitting under the adjacent sink. Cut the connector pipe, if necessary, to the proper length. Connect the pipe to the elbow and T-fitting using the nuts and washers provided with your PVC pipe kit and the existing nut and washer on the T-fitting.
The plastic nuts should be hand-tightened. Using channel-lock pliers or a pipe wrench is not recommended. For a dishwasher drain, you must replace the drain pipe that runs from the P-trap to the wall with a pipe made for dishwasher drains. Disconnect the old pipe, and measure it to get the length for the new pipe that has a connector for the dishwasher drain. Several problems requiring repair commonly crop up with garbage disposers or disposals. They can jam up when objects bind the impeller blades inside the appliance.
The drain fittings can loosen and cause leaking beneath the sink. In a double-basin sink, when it's only the disposer basin that backs up with water, the likelihood is that the drain fitting on the disposer is clogged. A disposal generally has no problem grinding most food waste, but it's what happens after the grinding that can cause a clog. Often this has to do with how ground food waste reacts to water or lack of water after the disposal unit grinds it up and sends it on its way toward the drain line.
When a garbage disposer clogs, you will often find the problem in the drain trap assembly located on the waste discharge side of the disposal. Disposals also can back up over time because the waste line or trap gets coated and eventually obstructed with food waste.
If your garbage disposal is draining very slowly or not at all, the problem is most likely in the drain trap—the U-shaped plumbing fitting that is located downstream of the disposal discharge pipe. The simplest way to prevent a clog is to make a habit of flushing the disposal with plenty of water when it is running and for several seconds after you turn it off. However, even the best disposals will eventually need to be replaced.
When that time comes, be prepared with these tips on what to consider when buying a garbage disposal. First, determine if a replacement is necessary. Sure, it may not be your top priority, but if you find yourself experiencing the following, it may be time to replace your garbage disposal:. There are two types of garbage disposalsto choose from: the continuous feed and the batch feed. Both get the job done; however, the continuous feed disposals are the easiest to use.
Also the most commonly used disposal, the continuous feed version has an open mouth and is operated by a switch. The batch feed disposal, on the other hand, requires that you place your food waste into the chamber and close the stopper lid to activate the food grinder inside. For example, a one-third or one-half horsepower HP motor is perfect for a single homeowner occasionally grinding soft vegetables.
A three-fourths or 1 HP motor, on the other hand, is much more suited to a large family that often eats at home and will provide smoother operation, finer pulverization and less jams — which equals less stress on your waste water system.
Similarly, some models offer additional features, such as sound baffles to lower the decibel level of the unit , anti-splash baffles to keep your sink cleaner and corrosion protection shields.
