Hang the disposal by aligning the three mounting tabs with the slide-up ramps on the mounting ring. Holding the disposal in place, turn the lower mounting ring until all three tabs are locked into the mounting assembly. The disposal will now hang by itself. Tighten the three mounting screws, ultimately tightening each screw a few turns at a time until the mounting assembly is evenly and tightly seated against the bottom of the sink.
STEP 4 – If you must use your hands (again, not advised) to pull out all that funky goo, see STEP 2. The disposal must be powered off and unplugged. No exceptions. Not even on a double-dog dare. Also, make sure your hand will actually fit into the opening so that you can eventually remove your hand from the opening. You may need your hand later. If you think it is going to be a tight fit, I’d suggest that you not try it all. You’ve been warned.
If the source is not a connection from above then your disposal needs to be replaced. Try cupping your hands around the very top under the sink while running water. The ring that seals the gasket turns clockwise to tighten. The only other repairable leak would be where the piping comes out the side. There can also be a smaller dishwasher drain hose above that.
My old built in guard got destroyed over the years. Rather than remove the whole disposal I ordered this, hoping it would solve the problem of the noise and the water and food particles that would fly out of the disposal onto my slightly hairy chest and face. This solved both problems. It is so quiet that it is like white noise. Such a calming sound that you can sleep to it.
So I know next to nothing about buying a garbage disposal, for the past ten years I’ve lived in huge cities and haven’t had any room (or necessity for that matter) to purchase one. Having recently bought a house, all that has changed. From dishwasher to washer to dryer to garbage disposal, I’m having to educate myself about them and purchase them with informed decision making skills. Yikes.
With the garbage disposal shopping, I quickly learned that the big brands are Waste King and Sinkerator and that those were the two best places to start. After going over several models and two trips to two separate best buys (who, by the way, really need to amp up their customer service model) I cheated and had my mom choose one for me. Sue me. So she chose this particular brand, and wow—it works really well, I can’t believe how easy it makes ... full review
Most modern kitchen sink drains are this dimension--both on the garbage disposal side and the "rinse" side. These are well made items that work very effectively. Unlike most kitchen sink stoppers that rest on top of the drain opening and extend upwards into the sink when you're doing dishes, these fit down into the large opening and seal the smaller opening above the garbage disposal or "rinse" sink drain strainer. In other words they seal the drain without extending upwards into the sink full of water.
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.
