When measuring the maximum height of a testable backflow device you measure to the _________________________________.

• A. Center of the device
• B. Outlet of the test ports
• C. Top of the device

Answer: (B)

The maximum height of a testable backflow device is measured to the outlet of the test ports because this measurement is critical for ensuring that the device is accessible for testing and maintenance. The outlet of the test ports is the point where testing equipment is connected to measure pressure and ensure the device is functioning properly. By measuring to the outlet, you establish a reference point that reflects the actual operational level of the device, which can affect its performance and accessibility for regular testing. Additionally, local codes often specify this standard to maintain uniformity in backflow prevention device installations, ensuring compliance with safety regulations.
