Assuming that you have already given the disposal the time it needs to run and clear the garbage, you probably have a congested drain line. We don’t recommend using chemical drain cleaners with a garbage disposal. You will very likely just damage the unit and end up with a sink full of toxic chemicals that you’ll eventually be forced to clean out manually. If the blockage doesn’t go down with the good ol’ baking soda and vinegar remedy, then calling a John Moore professional is your best bet. He or she will know exactly how to properly remove the bolts, disconnect the drain trap and remove the trap and the discharge drain pipe, check for clogs and any other obstructions, and finally clear the blockage with the latest and best tools. (See our previous post about good steps you can take when your kitchen sink is clogged!)

Personally I'd recommend if you have a disposal have it removed. Most people don't realize, there is very little you are supposed to put in them. Whereas, they are the primary reason for your kitchen sink drain getting clogged. Just use the trash, it could save you an expensive Drain cleaning bill. Here's a tip for y'all who do have them. After use let warm water run while it's still running for 3 to 4 minutes, that will help push everything to the bigger main drain .
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.
