Which standard do post indicator valves need to comply with regarding height above the grade?

Post indicator valves are critical components in fire protection systems, and their installation must adhere to specific standards that ensure proper operation and accessibility. The correct standard regarding the height of post indicator valves above grade is NFPA 13.

NFPA 13, which focuses on the installation of sprinklers and related equipment, specifies that post indicator valves should be installed at a height that ensures they are easily visible and accessible for operation. This requirement is essential to ensure that firefighters and system operators can quickly and effectively engage the valve during an emergency situation.

In contrast, while other standards like NFPA 25 pertain to testing and maintenance of fire protection systems, and IFC (International Fire Code) and IBC (International Building Code) provide general building and fire safety regulations, they do not explicitly define the height requirements for the installation of post indicator valves as NFPA 13 does. Therefore, adherence to NFPA 13 ensures compliance with industry best practices for fire safety.
