A South Florida backflow specialist you can actually reach
Billy Dominguez started 1A Backflow & Services after seeing how much clean water depends on a small, often-forgotten device. More than 25 years later, testing and inspecting backflow preventers is still all we do.
We work with residential owners, property management groups, plumbing companies, and contractors across Dade, Broward, Monroe, and Palm Beach counties. When we finish a test, we file the report with the right municipality and follow up two weeks before your next deadline so nothing slips through the cracks.
What We Do
From the annual test your county requires to a full review of your property's cross connections, here is how we keep your water system protected and compliant.
Backflow Testing & Certification
Annual testing and inspection of your backflow prevention assembly to confirm it is working properly and keep your property compliant with Florida code.
