A branch that enters from above may connect through a drop to a deeper sewer. The opening can appear high in the camera frame while the branch itself stays out of sight. The footage alone may show the entry without revealing the route above it.
Ask what was visible from the main
Save the clip, viewing direction, and distance. Ask whether a second access point could show the branch and whether property drawings identify its route.
Document the elevation change before planning work
If a repair affects the junction, have the contractor explain which sections will remain in service and how they will confirm the branch drains after the work.
