What is a valve’s purpose in a water distribution system?

A valve's primary purpose in a water distribution system is to regulate or control the flow of water. It enables operators to manage the distribution network efficiently, which includes turning the flow on or off in certain sections, adjusting water pressure, and directing the flow to different areas as needed. By controlling these parameters, valves play a crucial role in maintaining the functionality of the water system, ensuring that adequate water supply reaches various consumers while helping to prevent issues such as water hammer or backflow.

The other options do not accurately reflect the role of a valve. Increasing water temperature is not a function of a valve; rather, it is influenced by water heaters or environmental conditions. Filtering sediments is performed by filters, not valves, which are designed primarily for flow control. Storing excess water is the role of tanks or reservoirs, not valves that manage water flow within the distribution system.
