How many testable connections trigger the requirement for a certified Cross Connection ORC?

How many testable connections trigger the requirement for a certified Cross Connection ORC?

• A. Two or more
• B. Five or more
• C. Eight or more
• D. Ten or more

Answer: (B)

The key idea is the threshold that determines when formal oversight is required for backflow prevention. A "testable connection" means any connection in the water system that could backflow and therefore needs to be tested with a backflow prevention device. When there are five or more of these testable connections, regulations require a certified Cross Connection Control ORC to manage the program, perform the required tests, and keep the records. This level of complexity justifies having a trained professional handle the testing and compliance responsibilities. If there are fewer than five, the certification requirement isn’t triggered by the standard rule, which is why five or more is the specific trigger.
