Garbage disposal is an electrically powered appliance that is installed beneath your kitchen sink or within a dishwasher. For dishwashers without built-in garbage disposal, a drain line can be run to an external disposal

Inside the disposal is a series of rotating grinders and impellers which grind food down until it is small enough to flow through the drainage pipe. This prevents clogs caused by food piling up within the sewage system.

Garbage disposals should never be used unless the water is running because the water pushes the ground up food through the drainage lines and out of your home. Additionally, garbage disposals should be used only to shred food waste. Anything harder than food could cause the disposal to malfunction.
