Fire hydrant:
The need for fire hydrants developed with the advent of underground water systems. Previously, water was obtained from easily accessible public wells or ponds. During the 1600s, London, England, began installing an underground water system. When there was a fire, firefighters had to dig up the street and bore a hole in the wooden pipes. Later wooden plugs were inserted into pre-drilled holes at fixed intervals along the pipes to make it easier for the fire-fighters to get water. This gave rise to the term fire plug, which is still sometimes used to refer to a hydrant.
It is a fire protection measure, and a source of water provided in most urban, suburban and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire. Buildings nearby may qualify for an insurance discount since firefighters should be able to more rapidly extinguish a fire on the insured property.
Dry hydrants are used to supply water for fighting fires in rural areas where municipal water systems are not available. A dry hydrant is analogous to a standpipe. A dry hydrant is usually an unpressurized, permanently installed pipe that has one end below the water level of a lake or pond. The other end is above ground and has a hard sleeve connector. When needed, a pump fire engine will pump from the lake or pond by drafting water. This is done by vacuuming the air out the dry hydrant, hard sleeve, and the fire engines pump with a primer. Because lower pressure exist at the pump intake, atmospheric pressure on the pond or lake forces water into part of the dry hydrant above water, into the hard sleeve, and finally into the pump. This water can then be pumped by the engine's centrifugal pump.
     Inspection and maintenance: In most areas fire hydrants require annual inspections and maintenance - they normally only have a one year warranty which may vary from 5 to even 10 year warranties. These inspections are generally performed by the local municipalities but they often do not inspect hydrants that are identified as private. Private hydrants are usually located on larger properties to adequately protect large buildings in case of a fire and in order to comply with the fire code. Some companies are contracted out to inspect private fire hydrants unless the municipality has undertaken that task.
            Occasionally a stone or foreign object will mar the seat gasket. In this case, most hydrants have a special seat wrench that allows removal of the seat to replace the gasket or other broken parts without removing the hydrant from the ground. Hydrants extensions are also available for raising a hydrant if the grade around the hydrant changes. Without extending the height, the wrenches to remove caps would not clear and the break flanges for traffic models would not be located correctly in case they were hit. Hydrant repair kits are also available to repair sacrificial parts designed to break when hit by a vehicle.
            In areas subject to freezing temperatures, only a portion of the hydrant is above ground. A valve rod extends from the valve itself up through a seal at the top of the hydrant. This design is known as a "dry barrel" hydrant, in that the barrel, or vertical body of the hydrant, is normally dry. 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, hydrants are used with one or more valves in the above-ground portion. Unlike cold-weather hydrants, it is possible to turn the water supply on and off to each port. This style is known as a "wet barrel" hydrant.
