What is the primary function of a fire pump?

The primary function of a fire pump is to maintain pressure in the fire suppression system. Fire pumps are specifically designed to ensure that a reliable and adequate supply of water is available at the necessary pressure to effectively combat fires. They are critical in providing the required pressure that might not be available from the municipal water supply or during low-pressure conditions. This ensures that the fire protection systems, such as sprinkler systems or standpipe systems, can operate efficiently and provide immediate water flow when needed.

In the context of fire protection, maintaining adequate pressure is essential for the fire suppression system to deliver water effectively to extinguish flames. Fire pumps play a vital role in maintaining system integrity and ensuring that adequate water pressure is available at the points of use during an emergency.

The other options can be distinguished in their purposes: while supplying water for general use is common in plumbing systems, and landscaping requires water delivery, these are not the primary roles of a fire pump. Increasing water pressure may be involved, but it does not encompass the broader responsibility of sustaining system pressure specifically for fire suppression needs.
