What type of hydrants are commonly used in dry climates?

Dry barrel hydrants are specifically designed for use in dry climates where freezing temperatures can occur. Unlike wet barrel hydrants, which hold water in the body of the hydrant, dry barrel hydrants are constructed so that they do not retain water in the exposed parts of the hydrant. This design prevents water from freezing and potentially damaging the hydrant during cold weather.

When a dry barrel hydrant is opened, water flows from the underground supply into the hydrant while the upper part remains dry. This ensures reliable operation in areas where freezing is a concern, making dry barrel hydrants the preferred choice for regions that experience low temperatures. In contrast, wet barrel hydrants, which are more suitable for climates that do not experience freezing temperatures, would not function properly in these conditions.
