In which direction should you turn the top nut to fully open a hydrant?

Clockwise
Counterclockwise
Left
Right

The correct answer is: Counterclockwise

To fully open a hydrant, you should turn the top nut counterclockwise. This direction is standard for most hydrants and is designed to ensure that water can flow freely through the system. Turning the top nut counterclockwise aligns with the common theme in plumbing and various types of valves, where loosening and opening mechanisms are typically achieved by turning left. This action allows the internal components of the hydrant to lift and enable the water to flow. It is essential for firefighters and personnel handling hydrants to follow this standard procedure to ensure quick and effective access to water during an emergency situation. Understanding this operational detail is crucial for safety and efficiency on the job.
