At least now you know the roof vent was not plugged.
What did happen?
In many cases the vent pipe extends a bit into the tank,, once the contents reach the bottom of the tank it can no longer vent.. So pressure builds as breakdown happens and you get a bit of a bubble. It means TANK NEARLY FULL DUMP NOW!!!
Tank was no where near full. Only used it for a day and it had been emptied.
