Okay please educate me....you say when the toilet "burps" - you empty, others have said when it gurgles....
Our blackwater indicator does not work, the others work fine, so I have waited for the "gurgle" but really don't know what I am waiting for. Does the gurgle come from within the toilet, the pipes or the rig just groaning (just joking on that one...), but I was worried about letting it get tooooooo full - can there be any problems if it gets too full other than the obvious of not flushing?
