For any major issues with the garbage disposal, you should leave the job to a professional plumber only. Reaching your hand into the drain is dangerous, even if you believe the power is shut off. A plumber can help you evaluate the state of your disposal, and decide whether or not you need a new unit. Upgrading to a faster disposal unit with a higher horsepower can help to protect your pipes and make cleaning up after meals even easier.
IMPORTANT: Whenever you are working on your garbage disposal, inserting items, and/or inserting body parts into your garbage disposal unit, it should be UNPLUGGED and the POWER TO THE GARBAGE DISPOSAL UNIT SHOULD BE OFF! Failing to do so will put you at risk of SERIOUS INJURY. Also, if possible avoid placing your hands directly near the blades at the disposal. If you can, instead use a tool to wedge out items or check the blades for blockage.

Horsepower Ratings – Even garbage disposals that have a basic ½ HP motor are more than capable of handling softer waste and bones; however, if your kitchen’s food waste routinely includes bones, cores, and harder vegetables, like carrots or avocados, then you need to look for a garbage disposal with a 1 HP (or higher) motor. A more powerful motor will be able to grind hard waste finer and faster, which reduces your chances of developing clogged pipes.
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.
