The main components of a fire hydrant system are fire hoses, Hose reel, fire hydrants valves, and breechings inlets.
The system can either be a dry riser system or a wet riser system.
In a dry riser system, the water needed to fight a fire in an emergency is charged by the fire brigade. The breeching inlets are usually housed in cabinets installed in each floor of a building.
The wet riser holds pressurized water which is connected to the water mains and the water is kept in check by means of valves. The breeching inlets for this system are also housed in inlet cabinets that indicate the type of riser system in use.
A fire hose reel is designed to carry and manage a heavy, high pressure fire hose, keeping it ready and in good condition as a conduit for water in case a fire occurs, the circular reel drum also makes it easy to reel out the fire hose for use in a fire and to reel it in for storage.
