regular use. - Batch Feed Disposals: Require the food to be loaded and then activated,
providing added safety.
Preparing for Garbage Disposal Installation
Proper preparation ensures a smooth installation process and minimizes potential issues.
Tools and Materials Needed
- New garbage disposal unit - Plumber’s wrench - Screwdriver set - Pipe wrench -
Plumber’s putty - Bucket or container - Towels or rags - Electrical wire stripper (if wiring is
required) - Safety gloves and goggles
Assessing Your Current Setup
