A partial flow hose connection pressure regulating device must provide adequate pressure and volume to

• A. Move the device from its seat
• B. Hold the device in place
• C. Keep the device seated
• D. Push the device out of the seat

Answer: (A)

A partial-flow hose connection pressure-regulating device is designed to sit against its valve seat until there is enough pressure and flow to unseat it. The regulator’s purpose is to allow controlled water to pass to the hose, which happens only when the valve is lifted off the seat. If there isn’t enough pressure and volume to overcome the spring or seating force, the device stays seated and no regulated flow reaches the hose. Therefore, the required condition is to provide adequate pressure and volume to move the device from its seat so flow can occur.
