'Burping' toilet.......
Vent too far into tank
Vent clogged
Tank full
Vent.....when up on roof...pull vent line cap.
Is top of vent line at roof line or has it dropped down below?
Run a garden hose down vent line......open tank drain valve and blast water thru vent line to clear any possible blockage.
Tank full.....dump tank
I will try this when we pull the rig out again. Wish I had thought or been told this earlier. I have resealed the vents and slid the rig (just clears) its shelter.
thanks for this good idea
