Who has to test in Tampa Bay
The rule depends on the utility that sends your water bill. Each line below is from that utility's own page.
- City of Tampa Water Department: Devices are required where the Water Department identifies a backflow potential, including all commercial, industrial and multi-family facilities, properties on both potable and reclaimed water, properties with a well or pond, and in-ground irrigation.
- Hillsborough County Public Utilities: Every property owner with a backflow assembly must have it tested once a year, and the owner must repair or replace any assembly that fails.
- Pinellas County Utilities: The county installs backflow assemblies on properties with reclaimed water available, on commercial properties, for rebate program participants and on firelines at designated properties.
- Pasco County Utilities: All backflow preventers must be tested right after installation or repair and then every year. The property owner pays for testing, since the county does not own private assemblies.

Florida rules behind the local programs
State rules set the minimum; the utilities above add their own deadlines and tester registration.
- The rule says each CWS's written plan must specify test frequency, and sets a floor: assemblies required at non-residential service connections (any connection other than a residential one as defined in the rule) are tested after installation or repair and at least annually. The frequency is set inside each CWS's plan but may not be less strict than this floor.
- Assemblies required at residential service connections (two inches or less, building containing only dwelling units, including dedicated irrigation or fire connections) are tested at least every two years, not annually.
- The state requires each CWS's plan to set the frequency, tester qualifications and test procedures, so details differ by utility.
