A fire hydrant system is a network of pipes and valves that provide firefighters with access to water to fight fires.

How it works

A fire hydrant system connects to a water supply main.

Firefighters use hydrant wrenches and standpipes to attach fire hoses to the hydrant.

Firefighters pump water from the hydrant and spray it on the fire.

Components

Fire hydrants: These are connection points that allow firefighters to access water.

Pipes: These are made of PVC or CPVC and connect the hydrants to the water supply main.

Valves: These control the flow of water from the pipes into the hydrants.

Outlet nozzles: These are where firefighters connect their hoses to access the water.

Operating nut: This large nut on top of the hydrant allows firefighters to open and close the drain valve.

Fire hydrant systems are a safety measure required in some buildings.

They can be combined with other safety measures, like fire sprinkler systems
