 ADDITIONAL FEATURES OF InSinkErator Septic Assist

Wanting to give septic systems the best possible option, InSinkErator loaded this unit with a bunch of great features to help finally seal the deal.

One example is the SoundSeal Technology that it uses to deliver a quiet performance. Who says you have to deal with the noise of blades shredding waste?

It also makes use of a MultiGrind system, wherein the food bits go through two stages of grinding.

Lastly, it has this unique Bio-Charge feature, which is basically an enzyme treatment that keeps your septic system fresh, and odor-free. It also helps the grinding process by injecting millions of microorganisms that break down the food waste. This is automatically activated every time the disposer is operated.


PROS AND CONS OF InSinkErator Septic Assist

All of these nifty features are bundled in an affordable disposer that currently goes for a price of less than $210 dollars.

With almost no disadvantage other than the fact that it is more expensive than 1/2 HP and 1/3 HP units. This is another demonstration of InSinkErator at its finest form.
