What type of hydrant is used in areas subject to freezing?

A dry-barrel hydrant is specifically designed for use in areas where temperatures may drop to freezing. This type of hydrant features a design that prevents water from remaining in the barrel of the hydrant when it is not in use. By keeping the water supply below the frost line and ensuring that any residual water drains out, the risk of freezing is minimized. In contrast, a wet-barrel hydrant contains water in the barrel that can freeze in low temperatures, posing a significant risk in cold climates. Therefore, the dry-barrel hydrant's design makes it the appropriate choice in regions susceptible to freezing temperatures, maintaining functionality while preventing ice-related issues.
