Overview
The InSinkErator Evolution Septic Assist is a 3/4 HP continuous feed garbage disposal built for homes on septic systems, pairing SoundSeal noise reduction with an included Bio-Charge cartridge that injects microorganisms to help break down food waste.
InSinkErator's septic assist design doesn't just claim to be safe for septic tanks, a common concern homeowners have; it adds an automatic dose of bacteria meant to help waste break down once it reaches the tank.
- 3/4 HP Dura-Drive induction motor
- SoundSeal noise reduction technology
- Bio-Charge cartridge included for septic systems
- 2-Stage Multigrind technology
Who it's for
Best for homeowners on septic systems replacing an older or leaking disposal who want a quiet, direct swap. This unit runs physically large, so it suits standard or larger sink cabinets better than a compact double-basin setup with tight under-sink space.
Pros and cons
- Quiet operation compared to previous disposals owners had
- Bio-Charge cartridge adds septic-specific waste breakdown
- 3/4 HP motor handles tougher food scraps
- Larger and heavier, may need cabinet modification
- Installation can require updated plumbing fittings
- Heavy unit, awkward for a single installer
Performance notes
The 3/4 HP Dura-Drive induction motor and 2-Stage Multigrind mechanism are aimed at tougher food scraps, and SoundSeal is the layer that muffles noise during grinding.
