Backflow Prevention

Backflow prevention devices protect our drinking water from contamination.

A backflow preventer stops water inside your water pipes from returning or 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 preventer, which provides a physical barrier to backflow.

A backflow prevention device, which must be tested annually,  is required on any service connection, including connections where an in-ground irrigation system and those where a separate potable lawn meter is in place. 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.
