How should you respond if a hydrant is not delivering expected flow?

• A. Notify command, check connections, valve operation, and consider alternative water sources or relay
• B. Increase discharge pressure without checks
• C. Replace hydrant gauge
• D. Ignore and continue

Answer: (B)

When a hydrant isn’t delivering the expected flow, the priority is to verify the water supply and hydrant operation through a careful, coordinated check. Start by notifying command of the situation, then inspect the hydrant and connections: make sure the hydrant is fully opened, valves in the pump and supply lines are correctly set, hoses and fittings are secure and free of blockages, and there are no leaks or obstructions around the hydrant. If the hydrant and connections are in order, evaluate the water source by checking intake pressure and whether additional hydrants or a relay supply can be used to boost flow. Only after identifying and addressing the cause should you adjust discharge pressure or set up a relay to maintain safe, adequate flow. Blindly increasing pressure without verifying the cause can create safety risks and mechanical issues, so this systematic approach keeps both the water supply and equipment safe and effective.
