Clear 2nd floor blockage affecting master bathroom Customer was experiencing 2nd floor blockage in master bathroom affecting fixtures and laundry drain. Upon arrival i noticed sewage came back up through the shower drain. I pulled master toilet to run k400 cable machine to clear blockage. After running cable multiple times we were successful in restoring proper flow. We ran water in multiple fixtures to ensure we restored proper flow and were successful. Customer would like camera inspection to further investigate.
