Customer called us out for a whole home back up. I tested the shower and toilet on arrival and it quickly backed up. I recommended using a cable machine to clear the blockage and the customer agreed. I advised customer that he might have cast iron and included a waiver in the quote. I removed the toilet and ran a cable machine down the line successfully clearing it and retrieving roots. I recommended not to flush toilet paper until a sewer supervisor comes out 1/2/26 11-2. I reinstalled the toilet because I did not have any plugs.
