Fire Pump Testing Explained: Churn Tests vs. Annual Flow Tests
Why buildings have fire pumps, the difference between no-flow churn tests and annual flow tests, and what the results tell you about pump health.
Fire Sprinkler & Water-Based Systems
Fire Pump Inspection & Testing
When a building needs more water pressure than the city supply provides, the fire pump makes the difference. We test pumps on schedule and document performance against design.
What this service involves
Fire pumps boost water pressure to sprinkler and standpipe systems in high-rise buildings, large warehouses and facilities with high demand. They must start automatically and deliver rated flow and pressure when called on.
YearRound performs fire pump inspections, no-flow (churn) tests and annual flow tests, and compares results against the pump’s rated performance so you know whether it is ready to perform.
What’s included
- Periodic no-flow (churn) testing
- Annual flow testing and performance comparison
- Electric and diesel driver inspection
- Controller and transfer switch inspection
- Jockey pump and pressure maintenance check
- Pump room condition review
- Written test report with recorded readings
Why it matters
- A pump that does not start or cannot deliver rated pressure can leave upper floors or large areas without adequate sprinkler protection.
- NFPA 25 sets weekly or monthly no-flow testing (depending on pump driver and conditions) and annual flow testing for fire pumps.
- Recorded test data shows trends before a pump fails.
When you need this service
- Periodic or annual testing is due
- The pump fails to start, runs continuously or short-cycles
- Controller alarms or trouble signals
- Insurance or fire authority requested test results

How often should a fire pump be tested?
NFPA 25 calls for periodic no-flow (churn) testing — weekly or monthly depending on the pump driver and conditions — and an annual flow test. We confirm the right schedule for your pump and can set up a recurring program.
Do you test diesel fire pumps?
Yes. We inspect and test both electric and diesel-driven fire pumps.
Will a flow test cause water damage?
Flow tests discharge water through a test header or flow meter to a safe location. We plan the discharge path before testing.
