Home/Backflow Preventers
Certified Testers · Licensed · CFC 1433130Most Southwest Florida municipalities require annual backflow certification. We test the device, verify it performs, and file the paperwork with your municipality so your compliance never lapses.
Backflow occurs when contaminated water reverses direction and enters the potable water supply because of a pressure change in the plumbing system. Backflow prevention devices stop this, but they must be tested regularly to verify they still work. Most Fort Myers area municipalities require annual certification. United Plumbing's certified testers perform code-compliant testing on RPZ valves, double-check assemblies and pressure vacuum breakers, then complete the municipal reporting.
The risk arises where irrigation systems, commercial equipment connections or cross-connected plumbing allow non-potable water to mix with drinking water. A device that has failed internally gives no outward sign, which is why testing is scheduled rather than triggered by symptoms.
Failure to maintain certification can result in compliance notices, fines, or interruption of water service.
Where The Risk Comes From
Backflow risk increases when a plumbing system includes any of these. Most Southwest Florida properties have at least one.
RPZ valves, double-check assemblies and pressure vacuum breakers are engineered to prevent contaminated water entering the drinking supply. Regular inspection verifies they remain operational and compliant with municipal requirements.
Testing & Filing
Many Fort Myers municipalities require property owners to maintain annual backflow certification. Our certified testing services include:
United Plumbing completes inspections to local municipal standards and files the required reporting, which is the part property owners most often miss. A test that is performed but never submitted does not keep you compliant.
United serves twelve cities across three counties, and testing frequency, submission deadlines and which devices require certification are set locally rather than uniformly. We confirm what applies to your specific address and utility rather than assuming a regional default.
Sometimes a device must be installed or replaced to meet compliance requirements or correct a failure. That may be necessary when:
Our team installs and services irrigation backflow preventers, commercial RPZ assemblies, double-check valves and pool autofill protection systems using code-compliant installation standards. Because we both test and repair, a failed test does not mean finding a second contractor.
Backflow testing applies across a wide range of residential and commercial properties:
United coordinates inspections and certification for individual properties as well as multi-unit facilities requiring multiple device certifications on a single schedule. See commercial plumbing services for maintenance programs.
United Plumbing provides licensed backflow testing and certification throughout Bonita Springs, Cape Coral, Captiva, Estero, Fort Myers, Fort Myers Beach, North Fort Myers, Golden Gate, Marco Island, Naples, Punta Gorda, Sanibel, and surrounding communities.
Our certified technicians deliver accurate testing, reliable reporting, and code-compliant certification to help property owners maintain safe drinking water systems and municipal compliance.
How It Works

Device performance, pressure differential and internal valve condition all verified.
A failed device is repaired or replaced by the same team, quoted before work begins.
Certification documentation completed and submitted so your compliance stands.
Common Questions
Annual certification is the common requirement across Southwest Florida municipalities, though the specific interval and deadline are set by your local utility. We confirm what applies to your address rather than assuming a regional default.
Often yes, particularly with an irrigation system or a pool autofill line, because both create a cross-connection. Many homeowners are unaware they have a device until a compliance notice arrives.
It needs repair or replacement to regain certification. Because United both tests and repairs, that is handled by the same team rather than requiring a second contractor, and the repair is quoted before any work begins.
Yes. Certification documentation and official testing reports are completed and submitted to the municipality. This matters, because a test that is performed but never filed does not keep a property compliant.
Consequences are set by the utility and can include compliance notices, fines, or interruption of water service. If you have already received a notice, say so when booking so it can be prioritized.
RPZ assemblies, double-check valves and pressure vacuum breakers, across irrigation backflow preventers, commercial assemblies and pool autofill protection systems.
Yes. HOAs, multi-family housing and commercial complexes often need several devices certified at once, and those are coordinated on a single schedule with consolidated reporting.
