Attempted to perform camera inspection of units via cleanout in front yard, due to the cleanout being installed incorrect I was unable to run camera up stream. Performed camera inspection down stream and everything looked in good condition. Went on roof and performed camera inspection of the two units sewer mains. Both units had root intrusions down the length of the lines. Recommended to customer to dig up connection located in car port closet and performing epoxy lining down each of the units sewer main to seal off the roots and prevent future issues.
