Our septic tank backed up. Popped the top and a think "cake" floated on
top of the first chamber. when moved away from the inlet the clog eased.
we had the pumping done. but you know the first chamber was not full.
It had only been three years since pumping. when we bought the place.
The question is what caused this floating mass? It seems full of air.
Could an exceptionally wet year, 163% of normal could be the cause?
