Conducting a thorough inspection in Burr Ridge, IL, I utilized a video camera to assess the sewer system from an exterior clay cleanout located approximately 4 feet deep in the front yard near the sidewalk. The inspection extended 52 feet upstream to a catch basin in the back patio, revealing minor root intrusion in the 6-inch clay pipe and minor corrosion in the 4-inch cast iron. Downstream, 32 feet to the city main line, the system was clear.
