Under NFPA 25, how often should a fire pump's pressure relief valve be tested?

The requirement for testing a fire pump's pressure relief valve under NFPA 25 is set at an annual frequency. This annual testing is critical because it ensures that the pressure relief valve functions correctly and can effectively relieve excess pressure in the system. If this valve fails to operate when needed, it can lead to potentially dangerous pressure build-up that could damage the fire protection system or create life safety hazards.

Regular testing, as specified, allows for the early identification of any issues or failures within the valve, ensuring that it remains in proper working condition. This helps maintain the integrity of the fire pump system and ensures compliance with safety regulations. By adhering to the annual requirement, facilities can ensure that they are taking proactive steps to protect their buildings and occupants from fire hazards.

Understanding the testing intervals is crucial as they are designed to align with industry best practices and safety standards that help safeguard property and lives in the event of a fire.
