Sewer line backing up upon arrival. Customer stated after washing multiple loads of laundry the sewer line began to back up. Informed customer we could attempt to clear the blockage and run the camera to see what was causing the issue. Gave customer estimate, customer approved estimate. After running sewer machine pulled back roots and mud. Located the spot of the issue and informed customer we could dig up the sewer line and replace that section. Gave customer estimate, customer approved. After digging up bad section found entire line to be concrete. Informed customer it would be best to replace the entire line. Gave customer estimate, customer approved. Replaced entire line from house to the city tap with pvc. Installed two new clean outs one at the house and one at the tap. Ran camera to make sure line was clear and flowing. Line is now flowing properly and no longer is backing up. We will be back Monday to pick up concrete
