Dry-barrel fire hydrants are typically used in what type of environment?

Dry-barrel fire hydrants are specifically designed for environments where freezing temperatures can occur. In such climates, typical wet-barrel hydrants, which contain water at all times, would risk freezing and becoming non-operational during cold weather.

Dry-barrel hydrants, on the other hand, are constructed to prevent water from being trapped in the hydrant. When the hydrant is turned off, the water drains out of the barrel, keeping the mechanism above the frost line free of moisture. This design is critical in areas with low temperatures, where ice formation could obstruct service or damage equipment.

Given this design feature, dry-barrel hydrants are ideal for use in freezing environments, ensuring reliability and operational functionality when needed most.
