Florida conditions and backflow devices
Tampa assemblies sit outdoors year-round in heat, humidity and summer storms. Rubber seals and check valves age faster in that environment, and lawn irrigation runs much of the year, so a test every two years is a minimum, not a maximum. A device that's leaking or discharging between tests should be serviced right away.
Making sure the report counts
Use a certified technician
Only results from a certified backflow prevention device technician are accepted.
Seven-day window

Online filing

Reclaimed water and cross-connections
Some Tampa-area neighborhoods irrigate with reclaimed water. Reclaimed lines must never be connected to household drinking water plumbing; if you have both, keep hose connections and irrigation strictly separate and ask a backflow tester whether your property needs additional protection.
