What happens if a backflow device isn't repaired after a failed test?

When a backflow device fails a test and is not repaired, the most significant risk is that it will likely continue to malfunction, which poses a serious threat to the safety of the water supply. Backflow devices are designed to prevent contaminated water from flowing back into the clean water supply. If the device is not properly functioning due to a failure that remains unaddressed, there is a heightened risk of cross-contamination. This can lead to health hazards for anyone consuming the water, as harmful substances can enter the potable water system.

In this context, the integrity of the water supply hinges on the proper functioning of backflow prevention mechanisms. Continuous malfunction without repairs means that contaminants may be able to bypass these safeguards, nullifying the very purpose of the device. Ensuring prompt repairs after a failed test is essential to maintain the safety and quality of drinking water.
