A backflow prevention device is a critical water quality device that ensures that water flows in only one direction: from the city’s water main into your home or business.
These devices are designed to kick in if there is a loss of water pressure, for example, because of a water main break or a fire hydrant being opened. When water pressure drops, instead of the water being pushed forward, the water will flow backward into the city water lines.
A backflow prevention device stops water that’s already inside your pipes from flowing back to the main City water lines and contaminating the public water supply.
Who needs to install a backflow prevention device?
An approved backflow prevention device must be installed on any water service connection that the Water Department has identified as having a potential for backflow. This may include, but is not limited to the following:
- All commercial and industrial facilities congregate living facilities such as nursing and convalescent homes, and water treatment plants and pumping stations.
- Properties that are connected to both potable and reclaimed water supplies.
- Properties that have an auxiliary water supply, such as a well or a pond.
A list of facilities that usually require a backflow prevention device at the service connection can be found in the City of Tampa Municipal Code, Sec. 26-83.
Testing and Reporting Requirements
Backflow prevention devices must be tested by a certified backflow prevention device technician.
- Commercial Properties: Annual
- Residential Properties: Biannual (every 2 years)
How to submit test results
Certified test results must be received by the Water Department within seven (7) calendar days following the completion of the testing procedure.
