Food scraps range from 10% to 20% of household waste,[18] and are a problematic component of municipal waste, creating public health, sanitation and environmental problems at each step, beginning with internal storage and followed by truck-based collection. Burned in waste-to-energy facilities, the high water-content of food scraps means that their heating and burning consumes more energy than it generates; buried in landfills, food scraps decompose and generate methane gas; a greenhouse gas which contributes to climate change.[19]
InSinkErator garbage disposals provide a convenient and environmentally-conscious alternative to sending leftovers to landfills. Capable wastewater treatment plants can even recycle food scraps into energy and fertilizer. Plus, using garbage disposals can significantly reduce the amount of trash sent to landfills and reduce greenhouse gas emissions.
The snap ring fits into a groove on the lower end of the sink flange. When you’re working under the sink, it prevents the upper mounting bracket from falling off. Removing an old snap ring can be frustrating-unless you know this trick: Starting at the break in the ring, insert a thin-blade screwdriver between the ring and the flange. Pull down on the ring with the screwdriver’s blade and walk the blade around the ring. The ring will pop right off.
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.
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]
Lay the disposal on its side under the sink so you can make the electrical connections. Make sure the circuit breaker is off. Remove the plate on the bottom of the disposal to expose the wiring and use wire connectors to connect the wires from the disposal to the matching wires from the power supply. Finally, secure the power cord to the bottom of the disposal using the proper connection. Replace the plate to cover the wires. (See Fig 6)
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 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.
