The City of Winter Garden states that residential and commercial backflow prevention devices must be tested. Its utility service agreement requires the device to be maintained and tested every 12 months. The property owner arranges the test and remains responsible for making sure the City receives the completed report.
Winter Garden’s testing and reporting process
- Use a Florida-certified backflow tester registered with the City or able to provide the required certification and gauge-calibration records with the results.
- The tester submits the completed report directly to Winter Garden.
- The property owner remains responsible for confirming that submission occurred.
- The City’s tester list is provided as a courtesy and is not an endorsement.
- A qualified tester who is not already on the list may be used when acceptable certification and current equipment-calibration documentation accompany the report.
What happens during a residential test?
Winter Garden says a typical residential test takes about 15 minutes. Water is temporarily shut off, a calibrated gauge is connected, and the tester simulates backflow conditions to verify the assembly’s components. The device is normally outside, so the homeowner generally does not need to be present when access is clear.

If the device fails
The property owner is responsible for having a failed device repaired or replaced. The assembly should then be retested so a passing result can be documented and submitted.
Winter Garden backflow questions
Can I use any tester?
The City says only a registered Florida-certified tester may perform the test. Its published list is informational, and an otherwise qualified tester may be used when the required credentials and calibration information are provided.
Does the tester file the report?
Yes. Winter Garden says the registered tester submits the report directly, but the property owner is responsible for making sure it was sent.
What deadline should I follow?
Follow the date printed on the current City notice. Arrange service early enough to allow repair and retesting if the assembly does not pass.
