Black Tank Backing Up-Please help!
So we've gone dry camping twice in a new to me 2002 Cougar Fifth wheel. Both times we've had a blacktank/toilet backup issue. Emptying the black tank does not help. Yes I know about putting enough ...

My 5vr has two 45s and over a 3' drop from toilet to tank......no clogging issues.
It's a 3" line. Even if vent line was blocked toilet would flush OK until tank got full.
What I suspect is issue is black tank is a shallow tank and toilet line goes to far into tank OR tank is not sloped away from toilet line.
Flush contents are dropping directly under pipe opening and not moving out into tank. They then pile up and block toilet line.
Camera inspection would verify pipe length
Closer visual of tank would verify if sloped
Removal of tank is only means of repair.
Some drain/vent lines go thru a 'slip gasket' in opening to tank and some mfgs. actually glued the lines to fittings attached to top of tank ( :S )
And of course the tank outlet drain line IS glued to tank.
I hate having to mess with tanks, waste of fresh. They area PITA
Rotor Rooter ...........but then might be cheaper if you had a inexpensive backup camera , laptop adapter and some video cable :H
