Backflow Preventer Testing,
Inspection & Certification
Certified backflow preventer testing, inspection, repair, and annual certification for commercial properties and fire sprinkler systems across Miami-Dade, Broward, and South Florida. Florida DEP compliant, Florida licensed.
What We Provide
Backflow Preventer Testing, Inspection & Certification
Every commercial building connected to a public water supply is required to have a backflow preventer protecting that connection. When a backflow preventer fails or is not tested on schedule, contaminated water from the building's fire suppression or irrigation systems can flow back into the public water supply, creating a public health hazard.
At Firemax Fire Protection, our licensed fire protection company provides annual backflow preventer testing, inspection, repair, and certification for commercial properties across South Florida. We test all types of backflow prevention assemblies, including those connected to fire sprinkler systems, irrigation systems, and domestic water supplies.
Florida DEP regulations and local water utility requirements mandate annual backflow preventer testing by a licensed tester. Miami-Dade and Broward water utilities actively enforce this requirement, and properties with overdue testing face water service interruptions and fines.
"A failed backflow preventer allowed fire suppression chemicals to enter the domestic water line. The building had to be evacuated."
Backflow prevention failures are invisible until they create a serious public health problem. Annual testing is the only way to know your device is working.

Why It Matters
Common Backflow Prevention Problems We Solve
Backflow prevention is one of the most frequently overlooked compliance requirements in commercial property maintenance. These are the issues we encounter most often.
Overdue Annual Testing
Florida DEP regulations and local water utility requirements mandate annual backflow preventer testing. Many property managers lose track of due dates, particularly when managing multiple devices or multiple properties. Overdue testing results in notices of violation, fines, and potential water service interruptions.
Failed Device Assemblies
Backflow preventers contain internal check valves and seals that degrade over time. A device that fails testing must be repaired or replaced before a passing test report can be filed. We repair and rebuild assemblies in the field whenever possible to avoid the cost and delay of full replacement.
Devices Not Filed with the Water Utility
Miami-Dade and Broward water utilities require test results to be filed directly with the utility after each annual test. Many property owners complete testing but fail to confirm that results were actually received and processed by the utility, leaving them technically out of compliance even with a passing test.
Incorrect Assembly Type for the Hazard
Backflow prevention requirements vary based on the hazard level of the connected system. A fire sprinkler system connected to a chemical-based suppression loop requires a higher level of protection than a simple domestic water connection. Using the wrong assembly type can result in a code violation during AHJ inspection.
Deterioration in South Florida's Climate
Backflow preventers installed in South Florida's humid, salt-air environment deteriorate faster than in temperate climates. Corrosion of external components, internal seal degradation, and mineral buildup from hard water are all more prevalent here. Annual testing catches these issues before they result in device failure.
No Reminder System for Annual Due Dates
Backflow preventer testing due dates are easy to miss, especially for properties with multiple devices across different connections. We maintain a service calendar for every client and send reminders before due dates to ensure testing is never overdue.

Our Process
How Our Service Process Works
Every engagement follows a consistent process designed to get your building compliant quickly and keep it that way.
Device Location and Assessment
We locate all backflow prevention assemblies on the property, document their type, size, installation date, and last test date, and assess their physical condition before testing.
Certified Field Testing
We perform the required differential pressure test using calibrated test equipment, documenting results for each check valve and relief valve in the assembly.
Repair or Replacement
If any assembly fails testing, we repair or rebuild it in the field whenever possible and retest to confirm a passing result before issuing the certification report.
Utility Report Filing
We file the passing test report directly with Miami-Dade WASD, Broward County water utilities, or the applicable local utility, and provide you with a copy of the filed report for your records.

FAQ
Frequently Asked Questions
Florida DEP regulations and Miami-Dade and Broward water utility requirements mandate annual testing of all regulated backflow prevention assemblies. The test must be performed by a licensed backflow tester, and results must be filed with the water utility. Properties with overdue testing face violation notices, fines, and potential water service interruptions.
A failed backflow preventer must be repaired or replaced and retested before a passing report can be filed. We repair and rebuild assemblies in the field whenever possible to resolve the failure in a single visit. In some cases, a severely deteriorated assembly must be replaced with a new unit, which we can also supply and install.
Yes. Every fire sprinkler system connected to a public water supply is required to have a backflow preventer on the fire service connection. The type of assembly required depends on the hazard level of the sprinkler system. NFPA 25 requires the backflow preventer to be tested annually as part of the fire sprinkler system ITM program.
After completing a passing test, we file the results directly with Miami-Dade WASD, Broward County utilities, or the applicable local water authority on your behalf. You receive a copy of the filed report for your records. This is included in our standard service, so you do not need to manage the submission process yourself.
We maintain a service calendar for every client and send reminders before annual due dates. If you are not sure when your device was last tested, we can look up filing records with the water utility and assess the device's current status during an initial service visit.
Yes. We regularly combine backflow preventer testing with annual fire sprinkler system inspections, since NFPA 25 requires backflow testing as part of the sprinkler ITM program. Combining these services in a single visit reduces the number of appointments you need to coordinate and ensures all required documentation is completed together.
