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.
Warranty - The average industry warranty on a garbage disposal is one year; however, it is not uncommon to see manufacturers’ warranties that can extend up to ten years. As a general rule of thumb, the more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product they have made, but this is not always the case, so it is still important to do your homework.
Another method for cleaning and deodorizing your disposal unit is to sprinkle some baking soda in your unit and rinse it with about a cup of vinegar. This will create the bubbling “volcano effect” that kids love to watch so invite them in on this cleaning project. After allowing your mixture to sit for about 5 minutes, run hot water down the disposal until everything is thoroughly rinsed.
To replace a rubber gasket, your first step will be to unplug the cord to the garbage disposal and then disconnect the drain. If you have a dishwasher installed in your kitchen, the dishwasher drain hose will need to be disconnected from the disposer. With the cord and appropriate drain lines removed, you can now grasp the sides of the mounting nut and twist it in a counter clockwise motion, which unlocks the garbage disposal. The waste disposer should then drop right down.

In 1998, police took a leading Camorra figure into custody. Francesco Schiavone was caught hiding in a secret apartment near Naples behind a sliding wall of granite. The mayor of Naples, Antonio Bassolino, compared the arrest to that of Sicilian Mafia chief Salvatore Riina in 1993. Francesco Schiavone is now serving a life sentence after a criminal career which included arms trafficking, bomb attacks, armed robbery, and murder.
Update: As an aside, I also learned from my research that the best way to clean my disposal is to use citric acid. Having previously had no idea what citric acid was used for, I decided to order some from Amazon, going with the brand my sister uses: Citric Acid Powder - Ultra Fine Pure Powdered Crystals - Natural Preservative Food Grade Quality (16 oz) and gave it a whirl after 3 months of using my disposal. I let the citric acid sit with some water in the disposal for about ten minutes, and then I let it run for a solid 2 minutes. I repeated the procedure a few times and after about 30 minutes—wow, all the leftover gunk and food was flushed out of the disposal, leaving it clean with a very mild citrus scent. I feel like I’m becoming a real DIY at home kind of guy.
Abt carries both types of garbage disposal systems, continuous and batch feed. Continuous feed disposers are turned on and off with a power switch. They usually have a shield surrounding the hole in the sink so things do not come back out while being ground for disposal. Some continuous feed disposals have a reverse setting to help reduce jamming. Batch feed disposals operate when a lid is engaged, making them safer. They are a good option for families with children because food is unable to fly out of the sink. Batch feed food waste disposals are usually more expensive than the continuous feed disposals.
