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.
• Run water before and after you use the disposal If something has been put in the disposal that should not have been, use tongs or pliers to pull the material out. Never use your hand. To clean a garbage disposal of built-up sludge and debris, fill it with ice cubes and a cup of rock salt and then run it for about five seconds. If your garbage disposal smells bad, you can deodorize it by running warm water down it while you grind a quartered lemon.

As it's a direct replacement, I didn't even bother to go through the hassle or removing the old sink flange and having to putty in a new one as the existing one was just fine. It took me about 5 minutes to replace old with new - that's why I didn't bother with a different make. I'm an average Joe who does a few things around the house - mostly accompanied by a lot of cussing - so anything that makes such work quick and simple results in less swearing - which is a good thing right?!
The best part about this common issue is that in most instances anyone can fix the problem regardless of their skill-set. Additionally, you won't necessarily have to purchase any tools in order to get your disposal back in working mode. Most disposals come with an Allen wrench attached to them which should be the only tool you may need to fix a humming garbage disposal.
When rubber gaskets age, they can develop leaks. The gasket can dry up, crack, and leak when it is repeatedly exposed to long periods of disuse where no water is present in the drain pipe. Should an older garbage disposal be removed and then placed back, it will require a new rubber gasket to again achieve a watertight seal. Moreover, if a gasket is not evenly locked on all three sides, then it will develop a leak.
We have an annoying habit of letting the sink fill with dishes (I know *I* surely don't contribute to such, so it must be everyone else). Occasionally, the disposal backs up if you don't run it, so the sink begins to fill with water. When that happens, you can't see if there is any flatware in the bottom of the sink to get sucked down and chewed up. By sitting down in the drain, the Disposal Genie keeps that from happening, while letting you still run most of your scraps into the disposal.
If your garbage disposal just won’t turn at all, then it’s very likely that the disposal has lost power. Your unit may have blown a circuit, or it could be unplugged. First, check the plug for your garbage disposal to ensure that it’s secure. Next, locate the reset button on the underside of the unit, and push it. If neither of these things fixes the problem, look inside your electrical panel for signs of a tripped circuit.
