Televised sewer from a catch basin in back of the house to inspect because homeowner is getting sewer gas smells in the house. Sewer appears to be in good condition with no offsets cracks or deformations that could be causing smells to get into the house. There is an old check valve in the basement that a plumber has caulked and the homeowner believes that may have helped with the smell. The sewer could be lined to seal off all joints.
