Backflow Testing Process
Most cities in Sarasota and Manatee Counties require backflow prevention devices to be tested once a year by a certified technician. These inspections make sure your system works properly and keeps the water supply safe.
What to Expect During Your Backflow Test
- Visual Inspection: The plumber checks for leaks, corrosion, or damage around your backflow assembly.
- Pressure Differential Testing: Specialized gauges measure water pressure at each valve to ensure correct direction and performance.
- Calibration or Cleaning: If needed, the technician cleans and adjusts the device for optimal operation.
If your system doesn’t pass the test, our team explains the problem clearly and provides fast, cost-effective solutions, from small repairs to full device replacement.
