What is the required frequency for testing hose connections for pressure reducing and relief valves?

The required frequency for testing hose connections for pressure reducing and relief valves is every 60 months. This guideline is stated in NFPA 25, which governs the inspection, testing, and maintenance of water-based fire protection systems.

Testing hose connections, particularly those equipped with pressure reducing and relief valves, is crucial for ensuring the system can function properly during a fire emergency. The five-year interval allows for a balance between maintaining operational readiness and practical resource allocation, minimizing wear and tear on equipment while ensuring it is regularly evaluated for functionality and compliance with safety standards.

While there may be different frequencies outlined for various components in NFPA 25, the five-year requirement specifically reflects the need to periodically confirm that the pressure reducing and relief valves are operating correctly in conjunction with hose connections. This testing involves checking for leaks, confirming proper pressure settings, and ensuring that the equipment can respond effectively under pressure during an incident. Regular testing helps in preventing potential failures that could arise due to undetected issues over extended periods of time.
