After very careful planing for a couple of years,I screwed up!I put the old mobile home rite where I didn't want it.I can still build the new house within about 20 feet of where I wanted to without moving MH.The 64000$ question is ,how far from the septic tank can you get before you run into trouble?Is 80" of main feed line too far?The system in the new house will be very centralized with all water going the same route.It will be about 80"from farthest drain in the new house to the septic tank.The main line will be a straight shot to the tank,no elbows or turns.Am I o.k. or up you know witch creek?
