Abstract: Embodiments of the present invention include a system for locating and restoring service lines during pipeline restoration. According to some embodiments of the present invention, the system includes a movable chart, a plug with a marking magnet, and an attachment part. In some embodiments of the present invention, the movable cart is deployed along the inside of a pipeline. In some embodiments, the attachment part is movably coupled to the movable cart. The attachment part is configured to install a plug into the service line at a location where the service line intersects the pipeline, according to some embodiments. In other embodiments, the attachment part is configured to mark the location of the plug in the service line and remove the plug from the service line to restore a fluid connection between the service line and the pipeline.
