NFPA 22 Standard for Water Tanks for Private Fire Protection 2023 Edition

NFPA 22 Standard for Water Tanks for Private Fire Protection

NFPA 22, the Standard for Water Tanks Used in Private Fire Protection, gives detailed guidelines on how to design, build, install, and keep up with private fire protection tanks and the equipment that goes along with them.

The 2023 version has many changes that make it easier to use and bring it up to date with modern practices. Some of the main changes are: removing parts that were repeated to make the document clearer, updating sections about external forces like wind, snow, and live loads to match other standards and replace old ways of designing, changing.

the rules for sizing tanks to make sure pump suction pressure is considered during the design process, updating construction features of the tanks to follow new standards and recognize other relevant standards, adding more rules about valves to make maintenance easier, including specific distances between fill lines and suction pipes to stop cavitation in the fire pump, and fixing small errors like unit conversions where needed. Also, all references have been updated to the most recent codes and standards.
