Fire Hydrant System

A fire hydrant, (also known as fire pumps, hydrant boosters, fire water pumps)is a connection point by which firefighters can tap into a water supply. These are high pressure water pumps designed to increase the fire fighting capacity of a building by boosting the pressure in the hydrant service when mains is not enough, or when tank fed. A Fire Hydrant with fully-on valve , releasing pressure water. Safe Operating Procedure- Fire Hydrant The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water. Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated either full-on or full-off.
