During the field testing of the second check valve of an RP, if the gauge reading drops to the relief valve opening point when applying high side pressure, what action should be taken?

• A. Increase the pressure
• B. Bleed water through the low side of the gauge
• C. Close the valve
• D. Check the water supply

Answer: (B)

When field testing the second check valve of a Reduced Pressure (RP) assembly, if the gauge reading drops to the relief valve opening point while high side pressure is being applied, bleeding water through the low side of the gauge is the appropriate action. This process allows for the assessment of any potential backflow issues or negative pressure situations that could affect the reliability of the RP assembly. By bleeding water through the low side of the gauge, you can accurately determine if the second check valve is functioning correctly by monitoring the pressure changes that occur. If the gauge reading reflects normal operation after bleeding, it indicates that the system is properly handling pressure without creating a backflow hazard. This practice is vital in confirming the integrity of the RP assembly and ensuring that it is preventing contamination of the potable water supply effectively.
