Performed sewer inspection for customer Sewer is SDR Sewer piping. Overall condition of piping is good. However the line is very long from house to street connection. Due to this and settling in the soil the pipe has bellies every 10-15 ft holding about 1/2 in of water at its deepest sections. This could lead to potential back ups in the future. At time of inspection sewer is clear and just holding water at above mentioned bellies. Please see attached photos and videos. Recommend installing two way clean out in the middle of line outside due to length of sewer line.
