Sewer and drain cleaning. Rodded out the main sewer line from outside the cleanout of multiple-unit condos. Clean out the back of the unit. Hit blockage 80’ out. If blockage happens again, I recommend jetting of the system, seeing it around a 200’ run. No blockage when I arrived, and I had to run water for 20 minutes to charge the system to the rod. Ran water for 20 minutes after the system opened, and everything is working as it should.
