This user can attach this hose to a fire engine, which can use a powerful pump to boost the water pressure and possibly split it into multiple streams. Operation A New York City hydrant hooked to an FDNY fire engine with a turgid hose actively pumping water.The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kPa (50 pounds per square inch gauge (psig) this pressure varies according to region and depends on various factors including the size and location of the attached water main). Invention since then has targeted problems such as tampering, freezing, connection, reliability etc. Some countries provide access covers to these points, while others attach fixed above-ground hydrants - the first cast iron ones were patented in 1801 by Frederick Graff, then chief-engineer of the Philadelphia Water Works. When cast-iron pipes replaced the wood, permanent underground access points were included for the fire fighters.

Usage at partial-opening can consequently result in considerable flow directly into the soil surrounding the hydrant, which, over time, can cause severe scouring. The valving arrangement of most dry-barrel hydrants is for the drain valve to be open at anything other than full operation. When a fire hydrant is unobstructed, this is not a problem, as there is enough room to adequately position the hose.Most fire hydrant valves are not designed to throttle the water flow they are designed to be operated full-on or full-off. The water inside a charged hose line causes it to be very heavy and high water pressure causes it to be stiff and unable to make a tight turn while pressurized. A user should take care not to open or close a fire hydrant too quickly, as this can cause a water hammer, which can damage nearby pipes and equipment.

In North America the distances are commonly 3 to 5В m or 10 to 15В ft, often indicated by yellow or red paint on the curb. High-pressure water coursing through a potentially aging and corroding hydrant could cause a failure, injuring the firefighter operating the hydrant or bystanders.In most jurisdictions it is illegal to park a car within a certain distance of a fire hydrant. It is good practice to install valves on all orifices before using a hydrant as the protective caps are unreliable and can cause major injury if they fail.When operating a hydrant, a firefighter typically wears appropriate personal protective equipment, such as gloves and a helmet with face shield worn. These valves can be up to 12 inches in diameter to accommodate the large central 'steamer' orifices on many US hydrants.

Most fire hydrants in Australia are protected by a silver-coloured cover with a red top, secured to the ground with bolts to protect the hydrant from vandalism and unauthorized use. Such vandalism can also reduce municipal water pressure and impair firefighters' efforts to extinguish fires. Vandals sometimes cause monetary loss by wasting water when they open hydrants. Sometimes those simply seeking to play in the water remove the caps and open the valve, providing residents a place to play and cool off in summer.To prevent casual use or misuse, the hydrant requires special tools to be opened, usually a large wrench with a pentagonal socket. Today some US communities provide low flow sprinkler heads to enable residents to use the hydrants to cool off during hot weather, while gaining some control on water usage.

This style is known as a 'wet barrel' hydrant.Both wet- and dry-barrel hydrants typically have multiple outlets. Unlike with cold-weather hydrants, it is possible to turn the water supply on and off to each port. A drain valve underground opens when the water valve is completely closed this allows all water to drain from the hydrant body to prevent the hydrant from freezing.In warm areas, above-ground hydrants may be used with one or more valves in the above-ground portion. This design is known as a 'dry barrel' hydrant, in that the barrel, or vertical body of the hydrant, is normally dry.

The larger outlet is often a Storz connection if the local fire department has standardized on hose using Storz fittings for large diameter supply line. Dry-barrel hydrant has two smaller outlets and one larger outlet. Thus, wet barrel hydrants allow single outlets to be opened, requiring somewhat more effort, but simultaneously allowing more flexibility.A typical U.S.

Class AA hydrants (>1500 gpm) should have their nozzle caps and bonnet colored light blue, Class A hydrants (1000вЂ“1499В gpm), green, Class B hydrants (500вЂ“999В gpm), orange, Class C hydrants (0вЂ“499В gpm), red and inoperable or end-of-system (risking water hammer) black. In the United States, the AWWA and NFPA recommend hydrants be colored chrome yellow for rapid identification apart from the bonnet and nozzle caps which should be coded according to their available flow. Likewise, an older hydrant without a steamer connection may be called a 'village hydrant.'Above ground hydrants are coloured for purely practical criteria or more aesthetic reasons.

Where artistic and/or aesthetic considerations are paramount, hydrants can be extremely varied, or more subdued. In many localities, a white or purple top indicates that the hydrant provides non- potable water. In Ottawa, Ontario, hydrant colors communicate different messages to firefighters for example, if the inside of the hydrant is corroded so much that the interior diameter is too narrow for good pressure, it will be painted in a specific scheme to indicate to firefighters to move on to the next one. Other codings can be and frequently are used, some of greater complexity, incorporating pressure information, others more simplistic.
