Which of the following statements is true regarding booster pumps?

Booster pumps are designed to increase the pressure of water in a sprinkler system, enhancing the system's overall performance. They are commonly installed in basements or near gravity tanks because their primary function is to supplement the pressure provided by gravity tanks, which may not be sufficient under certain conditions, such as during peak demand or in larger buildings.

Having booster pumps near gravity tanks allows for more efficient operation, as they can draw water directly from the tank when additional pressure is needed. This placement optimizes the hydraulic design of the system, ensuring that water can be delivered effectively to all areas where it is required. The infrastructure and layout of many buildings make basements a practical choice for the installation of these pumps.

In contrast, while booster pumps can theoretically be installed at ground level and may operate in conjunction with systems that do not rely on gravity tanks, they are more typically associated with providing extra pressure when gravity systems alone are insufficient. Also, although most booster pumps are electric, they are not limited to electric systems alone since alternative power sources can be utilized in some applications.
