Description
Ensure the integrity of your water supply infrastructure with the NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenances, 2022 Edition. This standard is the definitive guide for designing and installing the underground piping and private hydrants that feed automatic sprinkler systems, standpipes, and other water-based fire protection equipment. It is a critical resource for site planners, civil engineers, and fire protection contractors.
The 2022 Edition has been updated to align closely with NFPA 13 (2022), ensuring seamless integration between underground and aboveground system requirements. This edition clarifies the rules for control valve locations, ensuring they are safely accessible during an emergency. It also provides updated specifications for underground piping materials, thrust restraint methods for grooved joints, and the installation of backflow preventers to protect municipal water supplies.
Key Updates in the 2022 Edition:
-
System alignment: Harmonized requirements with NFPA 13 to eliminate conflicts between underground and overhead piping standards.
-
Valve Location: Clarified requirements for the safe location of post-indicator valves (PIVs) and other control valves relative to the building.
