Was able to clear mainline clog for back bathroom via cleanout in backyard. Followed with camera inspection and found that customer had approximately 3-4 separate root intrusion in drains under home. Instead of performing invasive spot repairs which will require having to jackhammer flooring inside of home and trench, I recommend performing epoxy linning of sewer main via access on cleanout in backyard up towards where the sewer main transitions to ABS by front bathroom. This stretch is approximately 45’ long and will require having to perform re in statements to lateral drains throughout this run to include connections for back bathroom, kitchen drain and laundry drain. Performing epoxy lining will permanently seal all root intrusions as well as avoid having to perform any demo inside of home.
