What is the primary goal of a jockey pump in a fire protection system?

The primary goal of a jockey pump in a fire protection system is to restore pressure to a desired level. Jockey pumps play a crucial role in maintaining the system pressure at an optimal level, compensating for minor fluctuations that can occur due to water usage or minor leaks. By achieving this stability, jockey pumps help ensure that the main fire pump remains in standby mode, activating only when there is a significant demand for water, such as during a fire event. This efficient operation helps to maintain overall system reliability and readiness for emergencies, ensuring that the fire protection system is effective when needed.

Other options, such as increasing water temperature, replacing the main sprinkler pump, or serving as a backup during pump failure, do not accurately capture the primary function of a jockey pump within the system. The focus of the jockey pump remains solely on managing system pressure rather than altering the water's physical properties or taking over the role of the main pumps.
