Came out for what sounded like mainline blockage. Arrived and found main floor toilet had overflowed out the bowl and flooded down to the basement. Homeowner approved us to pull toilet and camera/snake sewer line, as there was no outside cleanout. Pulled main floor powder room toilet and ran camera. Located blockage 4’ deep under brick front porch. Ran sewer machine down line and snaked out blockage. Found break in the sewer line with a large root intrusion. Cut hole in the bottom of the roots and restored flow to the line. Homeowner found out HOA is responsible for any issue outside the home. There used to be a large tree in front of the home that was the culprit. HOA cut down all of the trees in the neighborhood as this has happened numerous times. Left quote to jackhammer/cut out brick front porch and do sewer repair. Also left quote for water heater. No warranty on sewer cleaning services. Notified homeowner not to flush paper until HOA can repair sewer line as it WILL back up agai
