What is a manifold box used for?

A manifold box serves as a protective enclosure for multiple valves which are critical in managing irrigation systems. By housing these valves in a single unit, the manifold box not only organizes the irrigation components but also safeguards them from environmental factors and physical damage. This greatly simplifies maintenance and repairs, as all the valves are consolidated in one location, making it easy to access and operate the system. In an irrigation setup, multiple zones can be controlled via a series of valves, and a manifold box ensures that these are protected while facilitating efficient management and troubleshooting of the irrigation system.

Options that suggest different functions, such as controlling water pressure, filtering impurities, or connecting various types of piping, do not accurately reflect the primary purpose of a manifold box in irrigation design.
