Which document should be referenced for guidance on testing and inspecting private fire service mains?

The guidance on testing and inspecting private fire service mains is primarily found in NFPA 25, which addresses the inspection, testing, and maintenance of water-based fire protection systems. This standard details the required procedures to ensure that systems such as private fire service mains are functioning properly and comply with safety regulations. Proper testing and inspection are critical to verify the reliability of water supply systems used for fire protection, ensuring they perform as intended in an emergency situation.

Other documents like NFPA 70, NFPA 13, and NFPA 101 focus on different aspects of fire safety and protection systems. NFPA 70 covers electrical installations, NFPA 13 provides criteria for sprinkler systems specifically, and NFPA 101 outlines life safety requirements in buildings. While these standards are essential for specific components of fire safety, NFPA 25 is the one designed specifically to encompass the inspection and testing practices related directly to fire service mains and other water-based systems, making it the most relevant document for this purpose.
