What must be done with the original signed and tested date test report?

The correct answer involves submitting the original signed and tested date test report to the water purveyor. This procedure is critical in the backflow prevention process as it ensures that the results of the backflow testing are officially documented and communicated to the appropriate regulatory authority responsible for overseeing water safety in a community.

The water purveyor utilizes this information to maintain accurate records, monitor compliance with local and national water safety standards, and ensure that any necessary maintenance or corrective actions are taken promptly. By submitting the report, it helps keep the water supply safe from potential contamination due to backflow incidents.

Maintaining a communication channel with the water purveyor is essential for ensuring that the water system remains protected, particularly in areas where backflow prevention is necessary. This step is a key part of the overall management of backflow prevention systems and reflects the collaborative responsibility to uphold water quality standards.

In contrast, while keeping the original report on file is important for personal records and may be relevant for other stakeholders, the primary official action required is to submit it to the water purveyor. The other options, such as sending it to the manufacturer or posting it in public places, do not align with standard procedures and regulations regarding the management of test reports for backflow prevention devices.
