Backflow Prevention Practice Exam

A field test report for a double check valve assembly includes several details, but which of the following is NOT required?

1. Body material

2. Date of manufacture

3. Serial number

4. Working pressure (maximum)

The correct answer is: Body material

The field test report for a double check valve assembly is a critical document that helps ensure the assembly meets the necessary standards for backflow prevention. Among the details included in such reports, the working pressure (maximum) is vital as it reflects the operational limits of the assembly under which it should function efficiently. The serial number is also essential because it ties the specific assembly to its manufacturer, allowing for traceability and quality assurance. Additionally, the date of manufacture is important as it provides insight into the age of the valve, which could affect its reliability and performance over time. The body material, while it may provide useful information about the durability and compatibility of the valve with various fluids, is not a mandated item in the field test report. Therefore, it is not required for documentation, as the focus is on performance metrics and compliance with safety and operational standards rather than the specifics of the valve's construction material. This underscores the importance of mandated testing parameters over construction details in evaluating backflow prevention assemblies.
