Commercial sewer and drain cleaning. The sewer line that picks up the employees' bathroom, men’s shower, and laundry sewer line was backing up through the floor drain in the employee bathroom. I rodded from a clean out in the employee bathroom floor and was able to get the line open at about 35’ out. I continued to run water for the next 30 minutes while rodding line in and out from 20’ out to 65 or 75’ because it was a difficult run of pipe to rod. Flushed all toilets, urinals, ran the showers, utility sink, and all lav faucets for 30 minutes with no backup. Everything is working as it should.
