What is the primary purpose of flushing fire hydrants?

Flushing fire hydrants is primarily conducted to maintain water quality and ensure the operational functionality of the hydrants. When hydrants are flushed, stagnant water that may have accumulated in the system is removed, which helps eliminate sediment, rust, and other contaminants that can affect water quality. This process is vital for ensuring that the water supplied through the hydrants is safe and suitable for fire suppression. Additionally, regular flushing helps to verify that the hydrants are functioning properly, ensuring they can be relied upon in emergencies. This preventive maintenance contributes to the overall reliability of the water distribution system and public safety.
