Your garbage disposal probably doesn’t get much attention until it sounds like you dropped a pocketful of change down the sink. Whether yours needs replacing or you’re wondering what can actually go in it, a few basics can save you some frustration—and possibly a plumbing bill.

How Does a Garbage Disposal Work?
A garbage disposal uses a spinning plate and impellers to push food scraps against a grinding ring. Running water carries the ground particles down the drain. It’s designed to help with cleanup, but it isn’t a substitute for your trash can.
What Size Garbage Disposal Do You Need?
Horsepower is a good starting point, but your cooking habits matter just as much as household size. The GE Appliances Disposall® garbage disposers featured in the video cover some common options:
⅓ HP: Lighter use and smaller households.
½ HP: Everyday cooking and kitchen cleanup.
¾ HP: Frequent cooking, meal prep, and busier kitchens.
1 HP: Large households, heavy duty kitchen use
Before buying, check cabinet space, mounting compatibility, and whether you need a corded or non-corded model. More horsepower won’t help if the unit doesn’t fit under your sink.
What Should and Shouldn’t Go In?
Scrape large amounts of food into the trash or compost first. Use cold running water and feed appropriate scraps gradually. Keep grease, oil, utensils, and nonfood items out, and check your model’s manual for specific food restrictions.
On septic? Compatibility doesn’t mean unlimited food waste. Ground scraps still add solids to the tank, so limiting disposal use matters.
Installing or Troubleshooting a Disposal
Replacement involves matching the mount, reconnecting the plumbing, and checking the electrical setup. A disposal that stops working may need an obstruction cleared or an overload reset rather than replacement. Always disconnect power before investigating, and never reach inside.
