Customer having back up issues upon arrival. Customer stated the toilet downstairs was backing up but has since stopped backing up. Informed customer we could run the camera down the line and locate the issue. Gave customer estimate, customer approved estimate. After running camera found root ball below the porch as well as most of the sewer line was back pitched and there is a crack in the cast iron at the foundation. Gave customer 3 options for replacing just a section of the sewer line, or replacing the whole line.
