NFPA 25 mandates the maintenance of fire pump systems in good working condition. It is required to maintain, inspect, test and provide maintenance reports regularly. Inspections are carried out annually to ensure that everything is in order.

Typical work performed during an inspection include:

• • Isolate sprinkler system so the pump flow test can be completed using the flow rates as required by NFPA.
  • Connect hoses to test header and run to hose mongers.
  • Open test header.
  • Reduce water pressure to determine the turn on-pressure, activating the fire pump.
  • Run the fire pump under a no-flow or churn pressure status.
  • Record suction and discharge pressure, voltage, amps, and temperature of the bearings and RPM on the test report.
  • Run the fire pumps under 100% capacity using the test header valves to regulate the flow.
  • Record suction and discharge pressure, voltage, amps, and temperature of the bearings and RPM on the test report; note number of hoses used and pitot pressure from each hose.
  • Run the fire pump under 150% capacity.
  • Record suction and discharge pressure, voltage, amps, and temperature of the bearings and RPM on the test report; note number of hoses used and pitot pressure from each hose.
  • Upon completion, the fire pump is reset to its normal operating conditions.
  • Tag all devices as required and perform required record keeping.
