HYDRAYANT

About HYDRAYANT

A hydrant is an upright pipe, valve, and spout apparatus typically installed on public streets or near buildings, serving as a vital, high-pressure water source for firefighting and municipal services. Primarily used to connect fire hoses to water mains, they ensure quick access to water to extinguish fires. [1, 2, 3]
