InSinkErator Evolution Septic Assist

Certain plumbing “experts” spread the misconception that a garbage disposer unit should never be utilized when the wastewater goes into the septic tank rather than the city’s sewer system. The explanation for the popularity of this erroneous idea comes from the fact that certain organic compounds are more difficult to dissolve than others and the standard bacterial cultures in septic tanks cannot break them apart.

However true this statement may be, it does not take into account that nowadays, there are garbage disposal units especially designed to operate in conjunction with a septic tank. This is the case with the Evolution Septic Assist model manufactured by InSinkErator, which is basically a retrofitted version of the Evolution Essential.
