Thanks for the replies so far.
Toilet lid was closed. Black tank only has a couple of gallons in it.
Water pump and fresh tank are never used, I only camp with hook ups.
Vent has no leaks. Pipe cap is intact on roof with no leeks.
My cleaning procedure is as follows:
Dump black completely, let run for a few minutes via black flush sprayer, when finished I close the black valve and do a 60 second count with black flush running to put a couple of gallon back in black tank. Turn off black tank sprayer.
Go into trailer, open toilet and pour in bottle of blue chemical.
Close empty toilet lid. It bugs me that the water was clear, and not blue tinted from the chemical...... The black tank is not full, when I flushed the toilet, the clear water fell into tank as normal.
To me, the water could not have come from the black tank. No water pump either, lid closed, no leaks from above. Sounds crazy but these are the facts.
Well, the only thing left is Gremlins or maybe the Space Aliens that put that monolith thing in the desert.
