Multiple points of connection are used to:

• A. Supply water from different sources or to different zones with varying pressure needs.
• B. Avoid high pressures
• C. Eliminate the need for a pump.
• D. Simplify irrigation head layout

Answer: (A)

The idea behind using multiple points of connection is to tailor the water supply to different parts of the system by matching sources and zones to their specific pressure needs. In an irrigation layout, not all areas operate at the same pressure—some zones are farther away, some are on higher ground, and some areas draw more flow. By tying into more than one source or by feeding separate zones from separate mains (each with its own valve or regulator), you can deliver the right pressure to each area. This keeps sprinkler heads operating within their intended pressure ranges, improves uniformity, and allows for flexibility or redundancy if one source isn’t available. The other options don’t address this core need to balance supply and pressure across multiple zones or sources.
