Which of the following pieces of information is NOT required on a Backflow report?

In the context of backflow prevention and reporting, the main purpose of a backflow report is to document critical details about the backflow prevention assembly to ensure it functions properly and complies with regulatory standards. Required information typically includes the assembly type, which identifies the specific design and functionality, and the serial number, which allows for traceability and tracking of the device.

Test results are essential as they provide evidence of the assembly's operational status and whether it successfully prevents backflow as intended.

Water temperature, while it may be relevant in certain circumstances regarding the performance of backflow prevention devices, is generally not a standard requirement for backflow reports. The main focus of such reports centers on the operational integrity of the assembly rather than specific water conditions, which is why this particular piece of information is often excluded from mandatory reporting criteria.
