Fibrous foods (celery, onion skins, corn husks), bones, cherry pits, coffee grounds in bulk, potato peels.

Best disposal brand?

InSinkErator or Waste King, both reliable. 1/2 HP for basic Tampa households, 3/4 HP for heavy cooking. See install guide.

How long do disposals last?

8-12 years typical. Tampa hard water + heavy use shortens.
