What action must be taken if a backflow test indicates the assembly is failing?

When a backflow test indicates that the assembly is failing, the appropriate action is to repair or replace the assembly. This is essential for maintaining the safety and integrity of the potable water supply. A failing backflow assembly poses a risk because it can allow contaminated water to flow back into the drinking water system, potentially introducing harmful pollutants or pathogens.

Repairing or replacing the assembly ensures that the backflow prevention system is functioning correctly, which is critical for protecting public health. Regular maintenance and prompt action after a test failure are key components of effective backflow prevention programs.

Continuing usage without concern, notifying the water authority, or ignoring the results does not address the underlying problem of a failing assembly and could jeopardize the safety of the water supply. Therefore, the proper and immediate response is to repair or replace the assembly as needed.
