When making a hydrant connection, the hydrant should be opened to what position?

When making a hydrant connection, the hydrant should be opened to a fully open position to ensure maximum water flow. This is crucial for effective firefighting operations, as it allows firefighters to access the full volume of water available from the hydrant. A fully open hydrant also helps prevent any potential damage that could occur from operating a hydrant that is only partially open, as the pressure within the lines can increase unnecessarily, leading to leaks or bursts.

Additionally, opening the hydrant fully minimizes the risk of creating turbulence or issues that can arise from restricted flow. In firefighting, timely and sufficient water supply can make a significant difference in controlling and extinguishing a fire, so establishing a solid connection with a fully open hydrant is vital for operational efficiency and safety.
