Certified Backflow Testing for Commercial Properties

Stay Compliant and Protect Your Water Supply

Florida requires backflow prevention assemblies at non-residential service connections to be tested after installation or repair and at least annually thereafter. We perform certified testing across South Florida and the Treasure Coast and hand back the completed documentation your local utility needs, so compliance is closed out rather than left to you to chase.

Annual Backflow Testing Made Simple and Compliant

Certified Testing That Meets Florida Requirements

Backflow preventers keep contaminated water from reversing into your clean water supply, which matters most in commercial environments where cross-connection risk is highest. State rule sets the floor, and your local utility administers the program and can require more. We test for restaurants and food service facilities, condos and multi-unit buildings, office and retail properties, and public and municipal facilities from Martin County through Miami-Dade, using calibrated equipment and filing the results.


Every test comes back with documentation you can put in a compliance file or hand to an inspector. Where a device fails, we repair or replace it and retest rather than leaving you to arrange a second vendor.
