A fire hydrant is essentially a pressurized valve connected to an underground water main.

 

1. Stand-by state – the main valve inside the hydrant is closed, so the barrel is dry (dry-barrel type) or filled with static water (wet-barrel type).

 

2. Activation – firefighters turn the operating nut; the stem rotates and lifts the gate or unseats the clapper, allowing water to flow upward through the barrel and out of the outlet ports.

 

3. Discharge – hoses are coupled to the outlets; the riser pipe delivers municipal pressure (typically 7–16 bar) immediately, so water reaches the nozzle without additional pumps unless long distances or high elevations require booster support.
