I just received my permit for installing replacement septic system. Because my leach field has a slope it calls for a serial distribution system that uses drop boxes.
The permit just states “two high holes and two low holes.” When I looked on the manufacturer’s website(Tuf-Tite)it’s apparent that that there’s many different configurations with drops of 2”-6” between the inlet and drainage holes, and some with the inlet out outlet are on the same plane, then some where the outlet looks to be 1” lower. So many choices! But which one to choose!

It looks like it will depend on your hill slope and the separations.

Hey, thanks for your response and the helpful diagrams. I contacted the regulating agency in the state(Oregon DEQ), and he sent me the drop box requirements: inlet and outlet ports at same elevation, and 6” of drop to drain ports. Tuf-tite DB6
