Which statement best describes the direct pumping water system?

• A. Water is pumped directly into the distribution system
• B. Water is stored above grade and gravity feeds
• C. Water is pumped into a reservoir first
• D. Water is supplied by a pressurized air system

Answer: (A)

Direct pumping means the fire pump pushes water straight into the building’s distribution piping as soon as demand occurs, with no intermediate storage tank or reservoir feeding the line. The pump draws from a water source and, when activated, delivers water directly to the mains to maintain pressure. This contrasts with gravity-fed systems, where water is stored above grade and fed by gravity, or systems that pump water into a reservoir before it reaches the distribution piping. An air-pressurized system describes a different method that uses an air chamber to help maintain pressure, not a direct pump-to-pipe arrangement. So pumping directly into the distribution system best fits what direct pumping describes.
