Forest River Model 362-bh-le

[pthomann]

Hello everyone -wondering if there are other owners out there that can explain how the tanks are connected in these units. I think I have 2 black tanks and 1 grey tank. I have a sewer and wastewater outlet at the front and back of the unit and an additional grey water outlet by the front outlet. In total, I have 3 valves in front and 2 valves in back. Question is does anyone else have similar floor plan and how are the tanks connected? We have a front and rear bathroom. There are two Gage's inside the trailer one by the main door and one in the rear bathroom. I am connected to sewer at a permanent location but am confused by hoe this plumbing iS connected?
