Types of fire hydrant systems:
Fire hydrants are of two types, those types are mentioned below:

Hydrant systems contain water and their pipes, therefore, these are only useful where the temperature does not fall under a certain limit so that the water in the pipes does not get frozen.
In dry hydrant systems the water is stored underground and the pipes are kept empty from water. Dry hydrants are used in the areas where there is a risk of freezing of water. When the water is required the valve is opened to get the water for extinguishing the fire.

There is a whole network of valves and pipes in the fire hydrant system. If a fire incident happens, firefighters search for the hydrant system. The valve of a fire hydrant is covered, and a pentagonal wrench is used to remove that cover. After removing the cover hose pipes are attached to the valve to get water.
There are nuts or bolts which are rotated and then water started flowing into the pipes. The hydrants are designed in such a way that they can maintain the pressure and direction of the flow of water.
