What Is a Garbage Disposal?
A garbage disposal is a kitchen appliance installed underneath your sink that grinds food waste into small particles so it can safely pass through plumbing pipes.
Garbage disposals help:
✔ reduce food waste

They are especially useful for busy households and frequent home cooks.

These are:

Most homeowners choose continuous feed models.
Batch Feed
Batch feed disposals only operate when a stopper is inserted.
These models are often considered safer because they prevent accidental operation while exposed.
However, they are usually more expensive and less common.
