The function of a jockey pump is to?

• A. Increase main water supply
• B. Trigger the alarm
• C. Maintain Pressure in the system
• D. Provide a continuous irrigation flow

Answer: (C)

The function being tested is maintaining pressure in the fire protection system. A jockey pump is a small auxiliary pump that starts automatically when system pressure drops below its set point and stops once pressure is back up. This keeps the system pressurized, preventing the main fire pump from cycling on and off for minor losses (like small leaks or normal valve operation) and helping ensure the system is ready to deliver water when truly needed. It’s not meant to increase the overall water supply from the source, trigger the alarm, or provide continuous irrigation flow.
