Hand dug down to sewer line. Found broken 45 where roots had infiltrated. Backside of 45 was completely blown out. Cut out damaged section and verified no further issue with camera. Repiped broken section and encased in hydrostatic foam. Tested repair to ensure a leak free install and proper function. There was some dirt built up inside the pipe due to previous companies attempt to jet the line. We ran lots of water and tried to break As dirt out with camera. Recommended jetting and let homeowner know we would have to jet the line if the dirt does cause a back up. No further issue at this time.
