An opening in the side of a sewer pipe may serve a fixture that is still connected, or it may lead to an old branch. A camera view from the main line shows the opening. It may leave the branch’s use uncertain, especially if it bends out of view.
Compare the view with the property history
Ask where the opening sits relative to the access point and any additions or former fixtures. Save a clip and the direction the camera traveled. If the plumber can safely trace flow from suspected fixtures, ask them to record which connections were confirmed.
Confirm its status before covering it
If a repair would pass the opening, ask the contractor how they will distinguish an active connection from a retired one. Have the proposal identify which branches will be kept open and how the crew will verify them afterward.
