At what minimum pressure should all new standpipe systems be tested hydrostatically?

All new standpipe systems should be tested hydrostatically at a minimum pressure of 200 psi. This pressure level is in place to ensure that the system can adequately handle the operational pressures it may experience in the field. The hydrostatic test is critical for verifying the integrity of the piping and connections, ensuring that there are no leaks or other weaknesses in the system that could jeopardize its performance during a fire emergency.

Testing at this specified pressure helps confirm that the standpipe system can withstand the stresses and potential fluctuations of pressure during actual use. This requirement is typically based on accepted safety standards and regulations, which are designed to maintain high safety and performance levels for fire protection systems. By adhering to this minimum pressure, technicians ensure both the reliability and safety of the standpipe systems installed in buildings.
