Backflow preventer manufacturers recommend that assemblies be field-tested annually and when_____?

Installed
Moved
Repaired or Installed
Shut down

The correct answer is: Repaired or Installed

Backflow preventer manufacturers recommend that assemblies be field-tested annually and when they are repaired or installed to ensure that they are functioning properly and providing the intended protection against the reverse flow of contaminated water into the potable water supply. Field testing at these critical times is essential because installation and repairs can affect the integrity and performance of the backflow prevention device. After installation, testing verifies that the assembly is correctly installed and able to prevent backflow effectively. When repairs are made, it is important to test the device again to account for any changes that might affect its functioning, ensuring that it still meets the necessary safety standards. Regular annual testing is part of a maintenance routine to detect any potential issues before they can lead to backflow incidents, reinforcing the importance of reliability in protecting public health and safety.
