Steady and Systematic Service Line Replacement Starts with a Certified Plumber

Polyethylene pipeline slipping with tracer wire in South Park, PA

In South Park Township, Steel City Natural Gas completed a natural gas service line replacement on a residential property. The existing underground steel line had developed a leak — a condition that is common in aging steel service lines and one that requires prompt attention for safety and code compliance. The old line was excavated and replaced with approved materials, restoring safe gas delivery to the home.

During the pressure test, a Kuhlman manometer was attached to the service riser valve to verify that the new line held pressure within required specifications. This step is not optional — it is a documented part of the inspection and certification process for both Peoples Gas and Columbia Gas service line work. Proper pressure testing confirms the integrity of the installation before the line is returned to service.
