During purging, where should the nozzle be held to vent air from the hose?

• A. At Ground Level
• B. Above the Level of the Pump Discharge
• C. Below the Level of the Pump Discharge
• D. Inline With the Pump Discharge

Answer: (B)

During purging, you want to give trapped air a clear escape path as the line fills with water. Holding the nozzle above the level of the pump discharge puts the nozzle at the highest point in the hose run, so air naturally rises and can vent out through the nozzle as you open the line. This helps prime the line and prevent air pockets that can delay water delivery or cause irregular flow. If you hold the nozzle at, or below, ground level or inline with the discharge, air tends to stay trapped in the hose and the line may not prime properly, delaying effective water flow.
