Dry Barrel Fire Hydrant
Dry barrel hydrants are commonly used in the cold regions because their underground valves ensure that no water will be left above ground, thus preventing themselves from freezing or breaking.
Water is drained or pumped from the barrel when the hydrant is not in use. Dry barrel hydrants are pressurized and drained through the workings of a main valve located in the base of the hydrant.
