TE certified will perform a camera inspection by removing a Fernco on the transition between PVC to cast-iron. TE Certified will attempt to see and locate the obstruction point, which may require a permanent fix. Following the camera inspection, I was able to locate a large belly within the sewer line. Customer was recommended to replace the cast-iron and have a new penetration installed, with replacing the defective sewer line outside of the home. The customer will let me know when they want to go forward with the work.
