Anyone who has experienced the wrath of a fire as it devours trees, houses and anything in its path, will realize the important role fire hydrants play. They are located in spots which are easily identified and accessible to firefighters and fire engines. They are also found in buildings along with fire extinguishers, sprinkler systems and fire hose reels.
Hydrants transport water in order to limit the amount of hose that firefighters need to use in order to speed up fire fighting. Fire engine hoses are hooked up to the hydrants for a supply of water that the fire engine supply may have already run out of. The pressure available to fire hydrants is important, and there must be enough pressure so that the fire hoses are able to force the water to break into fine droplets. The pressure also needs to be sufficient to allow multiple fire hydrants to operate at the same time.
