Backflow Prevention in Florida

A backflow preventer is a mechanical device that stops water from flowing backward into the clean water supply. Florida requires them on irrigation connections, fire suppression systems, and commercial properties where chemicals could contaminate drinking water. Many residential properties need one on the irrigation system.

Annual testing is required by most Florida water utilities. A certified backflow tester must verify the device operates correctly and submit the results to your water provider. Missing the annual test can result in a violation notice and eventual water shutoff.

Testing costs vary based on the device type and location. A simple double check valve test on a residential irrigation system costs less than testing a reduced pressure zone assembly on a commercial building. We provide the test, any needed repairs, and file the certification paperwork.

Yes. Most residential and many commercial backflow preventers install outdoors near the water meter or irrigation connection. The device needs protection from physical damage and must be accessible for annual testing. In Florida, freeze protection is rarely needed but the enclosure should protect against lawn equipment and vehicle contact.
