How to Troubleshoot Common Fire Pump Issues？

Here's a quick guide to troubleshooting common fire pump issues:


Pump Fails to Start: Check power supply, controller settings, battery charge (for diesel), and water suction pressure.

Low Pressure: Bleed air from the pump, checked for blockages, and inspected impellers for wear.

False Starts: Look for system leaks, and jockey pump issues, or recalibrate the pressure switch.

Excessive Noise/Vibration: Check for misalignment, worn bearings, or cavitation from low suction pressure.

Pump Overheating: Inspect the cooling system, ensure water flow, and prevent cavitation.

Low Water Flow: Clear blockages, ensure valves are fully open, and inspect discharge piping.

Pump Doesn’t Shut Off: Check the pressure switch, fix leaks, and ensure the jockey pump is working.

Diesel Pump Cold Start Issues: Use fuel additives, insulate the battery, and install block heaters.

Hope this helps keep your fire pumps in top shape!
