Sewer and drain cleaning. Basement sewer line backed up. The pump is working properly, and I was able to determine where the potential problem is. I rodded the sewer line from the pulled toilet in the basement and was able to get the line open. I captured the line and was able to see and locate a separation in the cast iron San line about 20’ out. I showed the customer and recommended being careful because the line will back up again and will most likely need to be fixed to resolve further issues. Went over options with the customer, and he will speak with Rudy if he wants to proceed in the future with the options This job is TBB per office
