What is the purpose of a master valve in an irrigation system?

• A. To measure water pressure
• B. To increase water flow
• C. To control water flow to all zones and prevent leaks when the system is off
• D. To monitor rainfall levels

Answer: (C)

The purpose of a master valve in an irrigation system is to control the water flow to all zones and prevent leaks when the system is off. This valve acts as a primary control point for the irrigation system, helping to ensure that water is only delivered to the zones when irrigation is scheduled to occur. When the system is inactive, the master valve closes to prevent any water from leaking through the system, effectively conserving water and ensuring efficiency. Furthermore, the installation of a master valve can contribute to the overall health of the irrigation system by minimizing the risk of damage from excess pressure or unintended operation. By keeping the system sealed when not in use, it also reduces the likelihood of water waste and helps maintain consistent operation across all zones. This function is essential for both efficiency and water management in any irrigation setup.
