Which component of a water distribution system helps to regulate flow and pressure?

The pressure regulator is the component of a water distribution system that plays a crucial role in regulating both flow and pressure. By controlling the pressure of the water within the system, it helps to ensure that the water is delivered at a consistent and safe level. This is particularly important in preventing damage to the infrastructure due to excessive pressure, which can occur if water is allowed to flow unchecked. Additionally, maintaining optimal pressure is essential for effective water service to consumers, ensuring that all areas receive adequate flow without the risk of bursts or leaks in the pipes.

Other components, while important, serve different purposes. For instance, a water meter measures the volume of water being used but does not regulate pressure or flow. Fire hydrants are crucial for providing access to water for firefighting but also do not control water flow or pressure. Storage tanks are used for storing water and can help maintain pressure through gravity, but they do not actively regulate flow or pressure like a pressure regulator does.
