Back in the old days of plumbing inspection, plumbers had one of two choices. A) They could use a snake or other tool and drive down into the plumbing system to make an educated guess of what was wrong with your drain. B) They could physically climb down into areas that were wide enough, like an outside drain or septic area and inspect the system.
