Yes indeed, we are also all too familiar with the "F" thing. Our principal residence leach bed has a stutter; there are 11 Le,Le,Legs x 100' each. I can get over this two-tone issue on the pond project. Our ban of anti-bacterial products includes bleach. I have had two opposing opinions on this subject. The county health dept says it's an overreaction. The guy that owns the hunney truck says keep it out or minimized. He also added to try using single ply TP (sorry, couldn't go to that level) and stressed the importance of NOT using tissue like Cottonelle...says it's like flushing a cotton T-shirt. I insisted on staying and watching the entire process of our first pump-out. It was uncharted territory for me and I wanted to learn and make sure of a good job. Whoa...!
