How many consecutive years can a fire pump be tested using a flow meter before it is tested using hose systems?

• A. 3 years
• B. 2 years
• C. 4 years
• D. 5 years

Answer: (B)

Testing a fire pump involves two methods: a flow-meter test to measure the actual discharge flow and a hose-system test to simulate real firefighting conditions. The flow-meter method gives precise flow and pressure data without the extra friction and dynamic effects of hose lines. But it doesn’t prove the pump can sustain the required flow through hoses, valves, and nozzles.

Because flow-meter tests are easier and less disruptive, they can be used for up to two consecutive years. After two such tests, a hose-system test is required to validate performance under real-world hose-line conditions, including friction losses and nozzle pressures. This sequencing balances efficiency with ensuring the pump still performs when actually delivering water through hoses.
