When conducting water flow tests, inspectors should take precautions to protect personnel, property, and water supply systems. Inspectors should notify the Authority Having Jurisdiction (AHJ), building occupants, and monitoring companies before testing to prevent false alarms or unnecessary emergency responses.

Testing should be coordinated with the water utility when required to ensure adequate system pressure and avoid service disruptions. Inspectors must verify that discharge points are safe, properly directed, and will not cause flooding, erosion, or property damage. Appropriate personal protective equipment (PPE) should be worn due to high water pressure, noise, and slip hazards. Inspectors should also confirm that valves are clearly identified and can be returned to their normal operating position after testing.

Finally, test results should be documented accurately, and any deficiencies should be reported and corrected to maintain reliable fire protection system performance.
