Impellers (or lugs) mounted on a spinning plate use centrifugal force to continuously force food waste particles against a stationary grind ring. The grind ring breaks down the food waste into very fine particles – virtually liquefying them. After they are ground, the running water flushes the particles through the grind ring, out of the disposer and into your wastewater pipe. From there, it flows to the wastewater treatment plant or your septic system.
When used properly (per our Installation Care and Use Manual) and connected to a properly grounded outlet or circuit, there are no issues with using an InSinkErator® disposer.
Contrary to common belief, food waste disposers do not have sharp blades. Instead they have two blunt rotating nubs (called lugs or impellers) which bat the food around and force it through holes along the perimeter of the grind chamber.
Disposers are okay to operate with properly sized septic systems. For example, if your system is sized for a dishwasher or clothes washer, it can handle a disposer. A disposer uses only about as much water per day as one flush of a toilet.
InSinkErator® is also the only manufacturer to offer a Septic Assist® model. Septic Assist injects a small squirt of liquid enzyme solution each time the disposer is turned on which helps to break down the food waste going to your septic system.
Most food waste created in the kitchen such as vegetable peelings, fruit rinds, chicken bones, scraps from meal plates and the like may be ground in the disposer. For fibrous materials like celery, artichoke leaves, etc., we recommend the Evolution Series® products which have advanced grind capabilities and can grind any foods.
For first-time installs, InSinkErator® recommends a professional installation. In select markets we can handle it for you. Select a local installer or call 1.844.599.7754.
