One advantage of this arrangement is that the valve cannot ____ from the hydrant.

• A. separate
• B. rotate independently
• C. leak at joint
• D. be removed easily

Answer: (A)

When a valve is designed to stay attached to the hydrant, the unit becomes a single, captive assembly. The main advantage is that the valve cannot separate from the hydrant. This keeps the valve always in place for isolating the line, reduces the chance of losing or misplacing the valve in the field, and speeds maintenance since you don’t have to hunt for a separate valve or worry about misalignment.

Rotating independently, leaking at a joint, or being removed easily aren’t the intended benefits of this arrangement. The design focuses on keeping the valve with the hydrant so it remains a reliable, integral part of the system.
