Increases pressure of the water in the system.

• A. Fixed Fire Pump
• B. Water Tank
• C. Primary Feeder
• D. Standpipe

Answer: (A)

The main idea here is how fire protection systems achieve enough pressure for effective firefighting. To meet required fire flows, the system often needs help pushing water through long runs, through elevations, and past friction losses in the piping. A fixed fire pump is specifically designed to boost the pressure within the fire protection system, ensuring adequate pressure and flow at outlets such as sprinklers, hose connections, or standpipes, especially when the upstream supply alone isn’t enough.

Water tanks can supply water via gravity, giving some pressure, but that pressure depends on height and water level and isn’t actively increased as demand rises. A primary feeder is a large supply line delivering water to the distribution system, but by itself it doesn’t increase pressure; it simply conveys water from the source. A standpipe provides outlets for firefighting access, but the pressure reaching those outlets is maintained or increased by the pumping system rather than by the standpipe itself.

So, the device that actively increases system pressure to meet fire-flow needs is the fixed fire pump.
