Closing the bale of a nozzle causes the line gauge to do what?

• A. Assume the pressure setting of the pressure gauge
• B. Drop to zero
• C. Increase
• D. Stay at zero

Answer: (A)

Closing the bale stops flow, but the pump continues to maintain the set discharge pressure. With no water moving, the pressure in the hose simply reflects that same discharge setting, so the line gauge reads the pump’s pressure setting rather than zero or continuing to rise. In short, the line gauge assumes the current discharge pressure when the nozzle is closed.
