What Is the Required Testing Frequency for Fire Pumps?

The required testing frequency for fire pumps is generally guided by NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. The key testing requirements include:

Weekly Testing

1. Electric Fire Pumps:
   • Perform a no-flow test (churn test) weekly to ensure the pump operates correctly.
2. Diesel Engine Fire Pumps:
   • Operate weekly for at least 30 minutes to ensure the engine and associated systems are functioning properly.

Annual Testing

1. Flow Testing:

   • Conduct an annual flow test to verify the pump meets its performance curve requirements. This involves running the pump at various flow rates (no flow, rated flow, and 150% of rated flow) and recording pressures and flow rates.

2. Hydraulic Performance:

   • Test and confirm the hydraulic performance is consistent with the manufacturer’s specifications.

Additional Considerations

• Jockey Pumps: Typically, jockey pumps do not require regular performance testing but should be inspected for proper functionality and alignment with system pressure settings.

• Start System Tests: Verify the proper operation of automatic start and stop features during each test.

• Inspection of Components:

  • Check the alignment of the pump, motor, or engine.
  • Inspect bearings, lubrication, seals, and other mechanical components.
  • Confirm proper operation of control panels and alarms.

These testing intervals ensure the fire pump is reliable and ready for operation during an emergency. Always check for any local code requirements or specific customer needs that might demand more frequent testing.
