As of 2014, a fire hydrant weighs a minimum of 500 pounds. Older hydrants used by firemen in the city of New York between 1904 and the 1930s weighed up to 800 lbs. Digging up a fire hydrant may cost between $2,000 and $4,000.
A fire hydrant is attached to a hose and supplies water at a pressure of the order of 350 kilopascal. The pressure varies from region to region, and it is dependent on the size and location of the water source. The other end of the hose connects to a fire engine, which may deploy a pump to add power to the flow of the water.
