Flow rate at the FP is higher than the design flow rating, what action should be taken?

• A. Place pump online or secure services
• B. Increase flow capacity
• C. Shut down the system
• D. Ignore and proceed

Answer: (A)

When the flow rate from the fire pump exceeds the design rating, the priority is to regain control of the firefighting water source by putting the pump online or bringing in trained personnel to service it. The design flow rating represents the safe, expected capacity of the system; anything higher suggests an abnormal condition that could indicate a measurement error, valve mispositioning, instrumentation fault, or a mechanical issue in the pump or downstream piping. By placing the pump online (if it isn’t already) or securing services, you ensure there is a controlled, monitored source of water and you get qualified people to diagnose and correct the root cause, preventing damage and maintaining reliable firefighting capability. Increasing flow capacity or ignoring the condition would either push the system beyond its safe limits or expose you to unaddressed faults, and shutting down the system would leave you without critical protection.
