What should be done if check valve number one is found to be leaking during the field testing of a Double Check Valve Assembly?

Replace check valve number one
Call a technician for further inspection
Test check valve number two
Adjust the water flow rate

The correct answer is: Test check valve number two

In the case of a leaking check valve during the testing of a Double Check Valve Assembly, testing check valve number two is a valid step. This approach is necessary because a Double Check Valve Assembly consists of two independently functioning check valves. If one is leaking, it is important to assess the operational status of the second check valve to determine if it is still providing the necessary protection against backflow. By performing this test, it can be determined whether the assembly as a whole is still effective. If check valve number two is functioning correctly, it may still prevent backflow despite the issue with the first valve, albeit not under optimal conditions. Meanwhile, if both check valves are found to be compromised, this indicates a more significant problem that will require further action, such as replacement or repair of the leaking component.
