How Fire Hydrant System Works
Type your paragrapA fire hydrant system is connected to an underground water distribution network. In case of fire, firefighters connect hoses to the hydrant valve, which releases pressurized water instantly.The system is supported by fire pumps and water reservoirs to maintain adequate flow and pressure. Proper system design ensures quick response, effective fire suppression, and maximum safety.h here
