Garbage Disposals Types

Batch feed disposals only activate when you insert and turn a special stopper in the drain opening. No wall switch. This makes them safer -- impossible to accidentally turn on while hands are near the grinding chamber. Ideal for homes with children, or kitchens where you prefer to load scraps, cover, then grind. Slightly slower workflow than continuous feed since you process one batch at a time, but the safety advantage is significant.

Continuous feed disposals are the standard type. Flip a wall switch, the motor runs, and you feed scraps in while water flows. The most popular and widely available disposal type -- 90%+ of residential installations. Available from 1/3 HP (budget, light use) to 1 HP (premium, heavy use). Higher HP grinds faster, handles tougher scraps, and jams less. The motor runs as long as the switch is on, so you can process scraps continuously during meal prep and cleanup.

Septic-safe disposals are designed for homes on septic systems rather than municipal sewer. They inject a dose of enzyme-based solution with each use that helps break down food particles in the septic tank. Standard disposals add solid waste to the septic load, which can overwhelm the system and require more frequent pumping. Septic-safe models reduce that impact. InSinkErator Evolution Septic Assist is the most well-known model. Important: even with a septic-safe disposal, you should still be conservative about what goes down the drain.
