New guy on the block here - - - so please correct me if my understanding of this matter is incorrect.

The reason that a "Waste Disposer" is not recommended in a home utilizing a septic systems is that the septic system may not be of sufficent capacity / size to handle the added water volume.

However, a system may be designed / spec'd to allow for the use of such waste units.

So, one may have to confirm the actual size of the current system and do some calculations to know with any certainty if the unit may or may not be an issue.

Anyway, that's my take on the matter.....

Oh ya, great site - thanks for all the info!
