Every once in a while I'll run into a situation where I've had to clear a main drain that is connected to a septic tank...
the customer has no clue where the tank is, and they have never pumped it while they have been living there.
I'm then called in for the "cheap" alternative...even though there is the probability it is the tank before the lateral
leading out to the tank.
The customer isn't normally happy when you've attempted to clear a line that you cannot open, knowing
that on top of your bill is coming a substantial pumping charge.
I would "prefer" that I'm called after the tank has been pumped, but most do not do that electively.
Anyone been in that scenario before?
