What does a master valve do in an irrigation system?

The master valve plays a crucial role in managing water flow within an irrigation system. Its primary function is to control the water flow into the system's main line. When activated, the master valve opens to allow water to flow into the irrigation system, and when it is turned off, it stops the flow, effectively managing the starting and stopping of the irrigation process. This control is vital for ensuring that the system operates efficiently and conserves water, as it can prevent leaks and other issues when the system is not in use.

While other components, such as pressure regulators and filters, serve different purposes within an irrigation system, the master valve's specific role in controlling the water flow distinguishes it from those functions.
