Which component is explicitly listed as part of a distribution system along with pipes, storage tanks and hydrants?

• A. Control valves
• B. Pumps
• C. Chlorination equipment
• D. Meters

Answer: (A)

In a fire protection water distribution system, the network that carries water from sources to its points of demand includes pipes, storage tanks, hydrants, and control valves. The role of control valves is to regulate and isolate portions of the distribution system, allowing designers and fire personnel to direct flow, maintain or adjust pressure, and isolate sections for maintenance or in case of a leak or contamination. This makes them an explicit, essential component of the distribution system alongside pipes, tanks, and hydrants.

Pumps, while important for providing pressure, are often treated as separate pumping equipment rather than a basic distribution-network component. Chlorination equipment is part of water treatment, not the distribution network itself. Meters are typically associated with the service side or monitoring rather than the core distribution system.
