How does fire haydrant work?

Answer 1

Quite simply, a fire hydrant is a large connection to utility-supplied water for use by (usually) fire fighters. It has a large valve to keep the water off while not in use or while connections are being made. Once connections are made, the valve can be opened. There are some hydrants that provide a connection to a body of water instead of a pressurized water distribution line. Hydrants have a few different connection possibilities. Some hydrants have just one fitting for a 4 inch line. Others have one or two 2 1/2 inch connections with or without the 4 inch connections. The idea in any case is to have a place to make a connection to the inlet side of a pump on some kind of fire equipment so that it can draw water from the main and distribute it to hose lines, other equipment or both of those things.

Answer 2

A fire hydrant is a connection point for firefighters to access water from the municipal water supply. When a fire hydrant is opened, it allows water to flow from the underground water distribution system through a hose to fight fires. Fire hydrants are usually located along streets and are color-coded to indicate their water flow capacity.
