What is a quick-coupler valve used for?

• A. To provide temporary water access for manual watering, testers, or filling features.
• B. To permanently shut off zones during frost.
• C. To regulate pressure in the main.
• D. To automatically switch between zones.

Answer: (D)

Quick-coupler valves provide temporary access to the irrigation mainline through a buried valve opened with a special key. This lets you tap water for manual watering, testing lines, or filling features without running the entire controller. They’re not meant to shut off zones, regulate pressure, or switch automatically between zones—those functions are handled by zone valves, pressure regulators, and the irrigation controller. So the best use is to provide temporary water access for manual tasks.
