Which hydrant type is depicted as having water in the barrel at all times?

• A. Wet-barrel
• B. Dry-barrel
• C. Drafting
• D. Dead end

Answer: (A)

Wet-barrel hydrants keep water in the barrel at all times. The barrel itself is part of the pressurized water system, so the valve is always filled and ready to discharge. When you open the hydrant, water flows immediately from the outlets because it’s already present in the barrel. This design is common in warmer climates where freezing isn’t a concern. In contrast, a dry-barrel hydrant stores water underground; the barrel stays dry and only fills with water when the hydrant is opened, which protects it from freezing. Drafting hydrants are intended for drawing water from external sources, not for having water in the barrel ready to go, and “dead end” refers to a street layout rather than a hydrant type.
