Attempted to clear customers clog via access on mainline roof of customers bathroom. Was not able to clear clog. Ran camera approximately 70’ out and whole line was under water. I believe customers septic tank that is connected to this bathroom is full and needs to be pumped out. Also noticed customers back toilet was draining slow. Augered toilet to clear clog. Recommended installation of mainline two way cleanout where sewer for both bathrooms exits the building to allow for future access.
