A distribution system consists of which components?

• A. Suppression System
• B. Distribution System
• C. Processing Facility
• D. Public Water Supply System

Answer: (B)

The main idea is that a distribution system is the network that carries water from the water source to the fire protection devices. This is why the option that names the distribution system is the best fit: it describes the piping, valves, hydrants, and other appurtenances that actually move water to sprinklers, standpipes, or other suppression points. The suppression system refers to the devices that release water at the protected locations, not the network that delivers it. The processing facility isn’t part of the fire protection water network, and the public water supply system is the source of water, not the distribution network itself. In practice, a distribution system includes piping, fittings, valves, backflow preventers, and often pumps and controls that help maintain pressure and ensure water is available where needed.
