I must have learned that here. It makes sense to me because if the tank were full or nearly full you could overfill the tank pretty quickly. The water static in the vent pipe would increase the pressure of the water in the tank as it pushes against the water in the stack.
I will keep looking because I know I saw it somewhere.
It may be a sticker on the camper.
I dont doubt that you are right about the manual stating this .
But I just cant figure out why FR or the tank manufacture would say this when the excess water cannot create pressure since the water replaces the air and it goes up the stinky pipe .
Now I could see this statement be true if the tank was full then you may have a problem . but then again why would you be flushing it at the full mark anyway ?
Maybe this is just one of these warnings that only makes sense to the people for the reason the waring was placed ?
The other thing I cannot understand is these solar powered stinky vent fans that only really work when you open the toilet valve .
Same way with the stinky pipe air foil thing a ma jig that also does nothing unless the toilet valve is open .
