Does anyone have detailed schematics of the plumbing tanks (black) especially on this model. Floorplans do not show detailed routing of the plumbing tanks/pipes configuration. I have a plugged toilet in the upper, main bathroom. This bathroom is raised above the basement area and I am thinking that it has a sub, small tank with pipe leading to the main black tank lower and opposite the toilet black tank on the main floor level. My line of thinking is because I but a steel coat hanger down the toilet and it went into a secondary hole which I feel is the pipe leading to the main black tank. I have ruled out "poop pyramid, plugged roof vent, seal dislodged and stuck in bottom of tank, etc

Can anyone verify? I find it very frustrating that you cannot get a detailed layout with blueprint drawings for plumbing, electrical, etc.
