Private Fire Mains


    FireMainBlackAdaquate fire flow is essential to the protection of life and property.

    Projects that include new buildings or additions to existing building are evaluated for fire flow, to determine if they meet code requirements. If fire flow is deemed inadaquate, the installation of a private fire service main may be necessary.

    A private fire service main is "the pipe and its appurtenances on private property (1) between a source of water and the base of the system riser for water-based fire protection systems, (2) between a source of water and inlets to foam-making systems, (3) between a soruce of water and the base elbow of private hydrants or monitor nozzles, and (4) used as fire pump suction and discharge piping, (5) beginning at the inlet side of the check valve on a gravity or pressure tank"(NFPA 24).

    Below is the link to NFPA Standard 24 and the requirements for private fire service mains:
