Portsmouth Water Balance, Presentation to 2023 American Waterworks Association

Identifying the material of a service line can be challenging: local plumbing codes vary and different pipe material and fittings were used during different decades. The materials available today were not necessarily available decades ago. One approach to identifying the material is to physically inspect the piping. Service line pipes may be exposed where they enter the home through a basement wall or floor, at the water meter, or when discovered through excavating the dirt over the service line or where it connects to the water main.
