It,s not my problem

I spoke with someone today about his sewer, he swore black and blue it was not his fault, well let me tell you something now. It's your problem as it's a pumped sewer and unless you are a registered licensed plumber leave it alone. Some people have no understanding how their pumped sewer works, the Holding Tank probably has not reached the low level to be pumped out yet and it would be unusual a new system would have a fault. So difficult to hold your tongue and say mate you don't even know what I have forgotten.
