Upon arrival Brian showed Nick the employee restroom in the southwest part of the building and the sewage back up out of the floor drain. Nick checked other restrooms by the pharmacy and the front customer restrooms and found them to be ok. Nick checked the riser room and found two floor drains backed up associated with the restroom drain also the mop sink behind the restroom. Nick called Collin and asked for approval to clean the branch line from the clean out next to the coolers. Collin approved the work and gave Nick authorization to sign. Nick cleaned the line through the clean out by the cooler and found at 65 feet the line opened up Nick ran 100 feet of the cable. The clog was paper towels. We will not guarantee against abuse or foreign objects going into the line. Everything is open and flowing Brian will sanitize the affected areas.
