Food Waste Disposers explained

Many people are under the impression that food waste disposers utilise spinning blades to chop and break down food waste. In fact, nothing could be further than the truth.

InSinkErator food waste disposer units use no blades whatsoever. Instead, impellers mounted on a spinning plate use centrifugal power to force food waste particles against a grind ring. That ring breaks down the food waste into very fine particles – virtually liquefying them.

Running water from the tap then 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.

Safe on Septic

InSinkErator Food waste disposers have always been safe for properly sized septic systems. For example, if your system is sized for a dishwasher or clothes washer, it can handle a disposer. After all, a disposer uses only about as much water per day as one flush of a toilet.
