3. Is my plumbing capable of handling the task? If your current plumbing frequently clogs or backs up, then you should NOT install a new garbage disposer. The additional waste that a garbage disposal creates will only increase the chances of one or both happening. Before installing a waste disposer, you’ll need to have the source of the problem identified and fixed.
Start by turning off and unplugging the garbage disposal. Next, you’ll need the wrench that came with your disposal. If you don’t have it, you can buy a replacement in a hardware store that sells your disposal brand. Find the hex-shaped opening at the bottom of the disposal unit. Turn the wrench clockwise to dislodge whatever’s blocking the flywheel. When the object dislodges, you’ll feel the flywheel start to turn easily. Reset the disposal and run cold water while quickly turning it on and off repeatedly.
Located in Benton Harbor, Michigan, the American based Whirlpool Corporation is an international manufacturer and marketer of home appliances. Whirlpool markets many different brands, including KitchenAid, Maytag, Jenn-Air, and Amana. Their line of in sink disposers offer an affordable entry level option for homeowners who want to install a garbage disposal in their home.
A clogged garbage disposal unit can leak when you try to operate it without removing the clogging. What clogs up garbage disposals? Normally this would be expandable food like rice and pasta. Even large animal bones can also result in clogging and possible leak. Although coffee grounds help eliminate odors, allowing it to accumulate in the drain of the disposer will result in clogging and potential leak.
Whether you repaired or replaced the leaking garbage disposal, test for any missed problem spots. Wipe the unit dry with a clean cloth, then unplug the sink drain (if plugged) and pour a few cups of dyed water into the drain once more. Use a flashlight to inspect the entire unit. If you don’t observe a leak, turn on the power to the disposal from your breaker box and plug in the disposal at the wall outlet.
Update: As an aside, I also learned from my research that the best way to clean my disposal is to use citric acid. Having previously had no idea what citric acid was used for, I decided to order some from Amazon, going with the brand my sister uses: Citric Acid Powder - Ultra Fine Pure Powdered Crystals - Natural Preservative Food Grade Quality (16 oz) and gave it a whirl after 3 months of using my disposal. I let the citric acid sit with some water in the disposal for about ten minutes, and then I let it run for a solid 2 minutes. I repeated the procedure a few times and after about 30 minutes—wow, all the leftover gunk and food was flushed out of the disposal, leaving it clean with a very mild citrus scent. I feel like I’m becoming a real DIY at home kind of guy.

In the United States, almost all garbage disposals on the market are manufactured by a handful of companies; although, many are branded under different names. For example, out of the top ten highest rated models on the market, InSinkErator makes eight of them. Whirlpool and WasteKing are the other two most well-known brands in the U.S. There are a wide range of models to choose from, ranging from basic $50.00 models to models equipped with all of the latest bells and whistles that can cost as much as $600.00. In most cases, you get what you pay for in terms of quality. Here is a brief overview of the top brands in the U.S.

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.

Some folks knocked the instructions. Take heart. It appears that the Waste King guys have heard the criticisms from the negative reviewers. I am guessing that they have been re-written to better explain the installation because they are really easy to follow. My best advice is this: don't be afraid of a difficult or confounding set of installation instructions. It is really easy. Here's what you do. Go to youtube.com and search for a video on How To Remove Your Existing Garbage Disposal because this is the hardest part. You will find one that matches yours. Watch it. I started removing the Badger incorrectly, stopped, watched a video, and then it was a piece of cake. In my case, I shouldn't have removed the three long screws before removing the body of the old one. You do it after it is disconnected. READ the instruction manual carefully. Then go ahead and youtube the Waste King installation video. It is very easy once you see it done. No filing or grinding gaskets, and Good Lord, no car jacks under your sink please. If it is hard then you are doing something wrong. STOP!!! Review the procedure. Start again. The directions are actually very explicit. The parts are well labeled. The diagrams show you what to do. The videos show you what to do. If you prepare yourself (15 minutes of reading and watching videos, tops) you will fly though the installation and be a happy person.
