Both bathrooms for units 8A and 8B were backing up. Cleared clog via roof access. Followed with camera inspection and found large root intrusion in sewer main for both units. Located issue under sidewalk in the back of the units. Strongly recommend digging up damaged section of piping and performing repair to avoid future issues as well as adding mainline cleanout. Due to the amount of turns and access I was unable to get my camera past this location to further inspect sewer line. Tenants will continue to experience clogs until issue is addressed
