ToggleThe Role and Function of a Garbage Disposal
A garbage disposal unit is designed to break down food waste into tiny particles so that they can be flushed away. This eliminates potential problems associated with throwing away certain types of foods, where they can attract pests or create unpleasant smells.

Having a garbage disposal isn’t without its challenges though. For one thing, they’re not meant for all types of foods. For example, you should never throw fibrous vegetables, bones, grease or oil into the unit as they can cause issues such as clogs or jams.
Importance of Regular Cleaning
