Fire Pump Testing in Denver
Your fire pump is the heart of the system — and NFPA 25 requires it proven every year at three flow points. We run full annual flow tests, weekly churn test setups, and pump controller diagnostics for diesel and electric pumps across the Denver metro.
What We Test
- check_circleAnnual 3-point flow test (0%, 100%, 150% of rated capacity)
- check_circleSuction and discharge pressure verification against the pump curve
- check_circleController transfer to alternate power source
- check_circleDiesel: battery, fuel, starter, and exhaust checks
- check_circleElectric: motor amps, voltage, and phase balance
- check_circleJockey pump cut-in / cut-out pressure setup
Calibrated Equipment, AHJ-Ready Results
We arrive with calibrated pitot tubes, flow meters, and gauges, and the required hose stream apparatus — calibration certificates available for AHJ submittal. You get a clean report that proves your pump performs to its listed curve.
If your pump fails the annual test, we document the failure, identify the root cause on the spot, and quote remediation — most issues we resolve the same visit or with one return trip. We've been testing pumps across Denver for 19 years.

FAQ
How often does a fire pump need testing in Denver? expand_more
NFPA 25 requires a weekly no-flow churn test (monthly for diesel) plus a full annual flow test at 0%, 100%, and 150% of rated capacity, all documented for the AHJ.
Do you test diesel and electric fire pumps? expand_more
Both — diesel, electric, and dual-drive arrangements. We service common drivers and controllers and bring all required test equipment.
What happens if my pump fails? expand_more
We document the failure, diagnose the root cause (impeller, controller, suction, transfer switch), and quote the fix immediately — often resolving it the same day.
