What distinguishes a jockey pump from other types of pumps in a sprinkler system?

A jockey pump is specifically designed to maintain system pressure by automatically activating when there is a slight drop in pressure within the sprinkler system. This feature allows the jockey pump to counter minor leaks or adjustments in the system without having to rely on the main fire pump, which typically engages during more significant pressure demands.

This automatic operation is critical to ensuring that the system is always primed and ready for action, keeping the sprinkler system at optimal performance levels. By maintaining consistent pressure, the jockey pump minimizes the risk of the fire pump cycling unnecessarily, thus ensuring the longevity and reliability of the overall fire protection system.

Other options do not accurately describe the unique function of a jockey pump in a sprinkler system. For example, jockey pumps do not operate continuously regardless of pressure; instead, they function based on pressure demands. Additionally, they are not manually operated, nor are they designed solely for emergency situations, as their primary role is to maintain system pressure under normal conditions.
