Backflow Prevention

A backflow preventer stops water inside your water pipes from flowing back to the City system if pressure is lost. Backflow can contaminate the water system. The basic mechanism for preventing backflow is a mechanical backflow prevention device, which provides a physical barrier to backflow.

An approved backflow prevention device, which must be tested annually, must be installed on the service connection that the department has identified as having a potential for backflow.

Refer to the City of Tampa Water Department Cross Connection Control and Backflow Prevention Manual for additional information. For a list of facilities that usually require a backflow prevention device at the service connection, refer to Tampa Code, Sec. 26-83.

Backflow prevention devices are provided and maintained annually by the Tampa Water Department at locations where dedicated potable irrigation meters installed prior to May 2014 or dedicated firelines and reclaimed water services are present. All other backflow prevention devices are customer owned and maintained and require customer-initiated annual testing by a certified backflow prevention device technician. Annual backflow prevention device test results for customer-owned backflow prevention devices must be submitted to the Tampa Water Department Cross-Connection Control Section. Call (813) 231-5266 for more information.
