How Often Should a Backflow Preventer Be Tested?
In many Florida cities, backflow preventers are required to be tested once per year. Annual testing helps confirm the assembly is still properly protecting the public drinking water supply from contamination caused by reverse water flow or cross-connections.
Testing requirements can vary depending on the type of property, local utility regulations, and the type of backflow prevention device installed.
Why Annual Backflow Testing Is Important
Backflow prevention assemblies contain internal valves, seals, springs, and moving components that naturally wear over time.
Annual testing helps verify the device is still functioning correctly and protecting potable water systems from contamination.
If a device fails testing, repairs or replacement may be required before certification can be completed.
