Conducted a flow test on a fire hydrant to ensure adequate water pressure for emergency use. First, I attached a diffuser to the hydrant outlet and used a Pitot gauge to measure the water flow. The static pressure read 65 psi, while the residual pressure dropped to 45 psi during the flow. I also measured the flow rate, which was within acceptable limits for the area. After completing the test, I closed the hydrant slowly to prevent water hammer and documented the results for compliance with NFPA 291 standards. The hydrant is now ready for service.
