Upon arrival, customer advised me that his upstairs shower and toilet were backing up. After diagnosis we determine that the clog was in the branch arm to the waist stack. I advised customer that we would need to pull the toilet and run a snake. After pulling the toilet, we ran approximately 3 feet of K 45 snake to clear the stoppage. After stop is clear. We tested multiple times and no cloggage. We reseat the toilet, and customer satisfied.
