I just had a major issue occur. I was flushing the black tank on my 2015 big country and I thought I had turned off the pressure on the black tank flush and closed the valve, but Obviously I had forgotten to turn off the water at the valve. The sewage/water had backed up into the toilet, which makes sense, but then it did something completely unexpected, sewage was poring out of the ac vents and around the A/C unit as well as poring into the closet as well, I know I made a mistake and left the water on the black tank flush but I thought it was supposed to just drain on the roof of the unit! Why would it fill my ceiling and ac vents with sewage which poured all over the top of my bed! Can I get some advice on why this would happen and if this is by design? I would think that it would come out of the vent tube going to the roof and then on to the ground outside. I can understand why the toilet backed up but the ceiling and ac vents and around the ac unit itself? I have been through many rains in this unit and we have no roof leaks at all so why would my ac vents have sewage come out of them with me overfilling the black tanks? Any help would be appreciated.
