What is the required test pressure for a hydrostatic flow test in a new fire sprinkler system?

The required test pressure for a hydrostatic flow test in a new fire sprinkler system is typically set to ensure the system can handle the maximum pressure it might encounter in a real-world scenario. In the case of new installations, the standard test pressure is often 200 psi. This pressure is used to verify the integrity of the system and to check for leaks.

A hydrostatic test allows for the entire system, including pipes and fittings, to be tested under pressure that is higher than the normal operating pressure. This ensures that all components can withstand the operational pressures without failure or leakage. Test pressures are guidelines aligned with standards and codes that are intended to maintain safety and reliability in fire protection systems.
