Cross Connection Practice Exam

What information is not required in the results of a backflow preventers field test?

1. Test date

2. Location of the test

3. Date of manufacture

4. Type of backflow preventer

The correct answer is: Date of manufacture

The requirement for detailed information in the results of a backflow preventer's field test is crucial for ensuring the effectiveness and reliability of the device. The date of manufacture is not necessary for the field test results because the test focuses on the operational capability of the backflow preventer at the time of the test, rather than the specifics of when it was produced. Information such as the test date, the location of the test, and the type of backflow preventer are essential. The test date provides a timeline for maintenance and compliance checks, the location is vital for identifying where the device is installed for regulatory and safety purposes, and knowing the type of backflow preventer helps determine the appropriate testing criteria and standards it must meet. Essentially, while the date of manufacture may be important for warranty or initial installation purposes, it does not impact the immediate effectiveness or compliance of the backflow prevention system during the test, making it the unnecessary information in this context.
