In this episode, what initially seems like a helpful cleanout ends up sending the technician in the wrong direction. Septic systems vary widely depending on the age of the property and previous plumbing modifications. Professionals rely on experience, pipe direction, ground slope, and system design knowledge to correctly locate underground septic tanks without unnecessary digging.
