What is one method of manual operation for an irrigation valve?

• A. Pressure Adjustment
• B. Manual Bleed Screw
• C. Spike Release
• D. Automatic Override

Answer: (B)

The method of manual operation for an irrigation valve referred to in the correct choice involves using a manual bleed screw. This component allows for the manual release of water pressure within the valve or irrigation system. By using the manual bleed screw, a user can quickly and effectively relieve pressure, which can help in troubleshooting issues, performing maintenance, or making adjustments to the system.

Manual bleed screws are commonly found on many types of irrigation valves and serve as a crucial feature for landscape maintenance professionals. They provide a straightforward way to access and control water flow without needing to shut down the entire irrigation system.

In contrast, options like pressure adjustment pertain more to changing the settings on a system rather than serving as a manual control for flow. Spike release is not a standard term associated with irrigation valves and does not provide a method for manually operating them. Automatic override indicates a system that operates without manual intervention, which does not fit the context of a manual operation for a valve.
