If the check valve springs are interchanged on a double check valve, how will the assembly be affected?

• A. It will not function
• B. It will not be adversely affected by the interchange
• C. It will leak
• D. It will require recalibration

Answer: (B)

If the check valve springs on a double check valve are interchanged, the assembly will function normally and will not be adversely affected by the interchange. This is because the design of the double check valve allows for flexible interaction between the check valves. Each check valve is intended to prevent backflow by utilizing a spring-loaded mechanism that closes against the flow of water when the pressure from the supply line drops or reverses. As long as the interchanged springs are of the same type and functioning correctly, they can compensate for each other, maintaining the proper sealing action. A well-designed double check valve assembly is robust enough to handle such changes, ensuring that it remains operational even if the springs are swapped. This adaptability is important for maintenance and repairs, as it allows technicians some leeway when replacing components without necessitating complete replacements or recalibrations.
