Why Is Backflow Testing Required?
Backflow prevention devices help protect drinking water from contamination caused by reverse water flow. Many water providers require annual testing to verify these devices are functioning properly and helping protect the public water supply.
When water pressure drops unexpectedly — due to a main break, firefighting activity, or heavy demand — contaminated water can flow backward into the clean water supply. A properly functioning backflow device prevents this from happening, keeping your drinking water safe.
