Overview
A 3/4 HP continuous feed garbage disposal built for septic systems, with EZ Connect hardwire installation, Quiet SoundSeal technology, and an included BOOST accessory that dispenses a Septic Guard liquid formula through the dishwasher inlet.
The Septic Guard liquid is a citrus-scented formula meant to help break down food waste buildup in septic tanks and pipes, dispensed via the BOOST accessory that attaches at the dishwasher inlet plug. InSinkErator backs the disposal itself with a 9-year limited warranty, while the BOOST accessory carries a separate 1-year limited warranty.
- 3/4 HP motor with Quiet SoundSeal technology
- EZ Connect hardwire adapter for DIY installation
- BOOST accessory dispenses Septic Guard liquid through the dishwasher inlet
- 9-year limited disposal warranty, 1-year on the BOOST accessory
Who it's for
Aimed at homeowners on a septic system who want a DIY-installable disposal with added digestion support for solids, plus anyone replacing an older, louder InSinkErator unit. Less relevant for buyers on municipal sewer with no septic concerns, since the Septic Guard feature is the point of this specific model.
What buyers say
From Amazon customer reviews.
Multiple reviewers switching from older InSinkErator units describe this one as a clear step up in quiet operation, with one saying it's so quiet they weren't sure it was running. Installation feedback was generally positive for DIY work, but one buyer flagged that the new retaining ring bends rather than springs back into place during flange tightening, recommending you keep your old ring as backup, and that the electrical quick-connect requires solid copper wire rather than stranded. One buyer questioned whether the Septic Guard liquid's odor control lives up to its claim.
