Customer has a sewage coming up from his tub and shower, also there was sewage coming from the joined wall of the back to back bathrooms. Pulled the toilet and tried running a snake down the line, ran camera down the line and they plumbed the toilets with an open ended double fixture tee. Starting digging outside to find the pipe and pop the line and install a cleanout. After hours of digging I found the original cleanout, customer will put the dirt back. Cleared the line with a snake, ran the camera and found a sizeable belly in the line going to the septic tank. Ran the camera towards the home and noticed dirt in the line, looks to be the tub has a break and found roots inside the line as well. Customer is remodeling the bathroom and will have us out to fix the line when the tub is removed. Ran water down the main sewer line for over ten minutes with no issues.
