Pulled toilet and cabled line. Cleared blockage. Tested. Blockage fully cleared. Attempted to camera. Mainline is cast iron and scale build up is very heavy. Wasn’t able to get camera very far. Recommended install of two way clean out for further issues and discussed lining of sewer for customer. Gave estimate for two way clean out. Reset toilet. Tested. No issues. Customer has exhausted her one free drain cleaning. Customer satisfied with todays service.
