We are lining a sewer from an outside clean out, the clay tile pipe had a hole in the top and also an area with cracks in the clay tile pipe with heavy roots growing in causing the sewer to back up into the house.
Video inspection of underground air ducts. Ducts are concrete with metal connections. Some metal connections are showing signs of rust. One area of duct is shifted and allowing sand to enter the system. Because of the location and configuration of the ducts it is recommended that it be either excavated and repaired or just block off the two effected registers.
