Customer called us out for a whole home back up. I inspected the bathroom and it took 15 minutes to show signs of a back up. I recommended clearing with a k400 in the daughters bedroom. Customer agreed I pulled the toilet and ran the cable machine but was unable to clear. I checked outside for a clean out and found one then ran the k-750 down. I was unsuccessful in clearing the blockage, it felt like I was hitting something very hard. I then attempted to clear the line with a blow bag and was successful. I reset the toilet with a new wax ring, closet bolts and china caps. Sewer supervisor will be out today 2-5.
