There are two main types of garbage disposers—continuous feed and batch feed. Continuous feed models are used by feeding in waste after being started and are more common. Batch feed units are used by placing waste inside the unit before being started. These types of units are started by placing a specially designed cover over the opening. Some covers manipulate a mechanical switch while others allow magnets in the cover to align with magnets in the unit. Small slits in the cover allow water to flow through. Batch feed models are considered safer, since the top of the disposal is covered during operation, preventing foreign objects from falling in.
When you buy a new disposal, the box will contain all the parts you need to install it. Before you jump into removing the old unit, take a few moments to familiarize yourself with all these parts. Put them together in the correct order and try out the locking mechanism. Understanding how everything fits together ahead of time will make the job a cinch.

Your garbage disposal is one of the biggest helpers in your kitchen. Without it, cleaning up after quick weeknight dinners, family feasts, and leisurely Sunday breakfasts would be much harder. While some garbage disposal problems can be fixed with a quick repair, sometimes it’s easier and more cost-efficient to replace the appliance. If you’re not sure whether or not to replace or repair your garbage disposal, check out these five signs your appliance is completely broken.
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.
When something blocks your disposal unit’s flywheel, you will start hearing a low humming sound, and you know you’ve got a jam. Un-jamming a garbage disposal is something that depends on the specific unit you own. Every single one has a function to shut off when they are stuck to the point of stalling the motor. This is so the motor doesn’t burn out. However, they are also designed so that anyone (and we mean anyone!) can remove whatever it is that is blocking your unit. Underneath every unit is a small slot, and pretty much all of them come with a tiny little wrench to match it. These are most commonly called hex-head wrenches. Yes, that little tool that you probably have no idea where it could possibly be has a very specific and important purpose. Mind blown, right?
A: A leaking garbage disposal often goes unnoticed until you confront a sopping cabinet, a foul-smelling puddle, or an audible drip-drip-drip from the unit. The fix can be frustrating, too, because the leak can stem from a number of components in the system. Fortunately, with a little sleuthing, you can zero in on the leak and—depending on the exact location—stop the icky oozing and repair the component that caused it. Worst case scenario, if it turns out that the garbage disposal must be replaced, installing a new one is a reasonable do-it-yourself task for those with basic plumbing skills. Read on to keep the cash you’d otherwise hand over to a pro.
A foul or foreign odor emanating from the garbage disposal that won’t go away no matter how thoroughly you have rinsed it, may also be a sign that it’s time to replace it. As the components in the grinding chamber wear out and the blades get duller and duller, food can easily get trapped inside and start to decompose. You may never have noticed the smell or have chosen to adapt and wait it out, but it may be a sign of a deeper problem. Visiting family members and dinner guests probably wouldn’t appreciate it very much, either.
The garbage disposal in your kitchen sink is a convenient way to get rid of scraps and leftovers, but when a foreign object like a glass gets caught in it, it can jam the mechanism and stop it from working. Removing a glass from a garbage disposal involves removing any large pieces of glass; dislodging the glass by inserting a wrench or broom handle into the bottom or top of the disposal; vacuuming the disposal; resetting it; or if none of the other steps work, removing the disposal and shaking out all of the glass. Read the following steps to find out how to remove a glass from a garbage disposal.
If your garbage disposal has become clogged, you’re likely to hear a muted humming noise when you flip the switch. This is an indication that your garbage disposal is getting power, but the blades aren’t able to turn. Very often, this happens when something hard and non-crushable has become caught in the blades at the bottom of the unit. To solve this problem, do the following:
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
