Mr. Allen I to am interested in the septic system that was on Bob's TV show. Yes, Judy a person must take all necessary precautions now adays before purchasing new products. I, know this because I to am a Senior Plumbing inspector for the City of Los Angeles and there is nothing worse for an inspector or the home owner than to find the product they have just spent money on is NOT APPROVED in their jurisdiction. If I remember correctly the system was call E-Z flow septic systems. Ifsomeone finds out please E-Mail me as well. If any one has a code question for me don't hesitate to E-Mail me.
