Only toilet in building is backing up, toilet bubbling when sink is running. Toilet need to be remove and snake. Customer stated that this is a reoccurring issue. I removed the only toilet in the building and ran a flex shaft about at 30 feet. I pulled back a lot of paper towels and tampons. I also pulled back a lot of root. There are a root intrusion and one of the connection of the pipe. Locate and give customer a quote.
