Service Overview
Backflow Preventer Installation Backed by 65+ Years of Local Experience
Backflow is a serious plumbing hazard that occurs when water flows in the wrong direction through your pipes — pulling contaminants, chemicals, or bacteria back into the clean water supply. For homeowners, this can mean dangerous drinking water. For commercial properties and construction sites, it can mean failed inspections, regulatory fines, and liability. Florida law requires backflow prevention devices on most commercial and irrigation connections, and many municipalities require them on residential systems as well. A properly installed and tested backflow preventer is your first line of defense against cross-contamination of the public water supply.
At Lapin Services, we have been protecting Central Florida homes and businesses since 1958. Our licensed plumbing technicians — operating under License CFC1428594 — assess your specific water system, recommend the correct backflow preventer type, and install it precisely to code. We handle permits, provide documentation, and explain your annual testing requirements so nothing falls through the cracks. Whether you need a new installation, a replacement, or a device upgrade to meet current code, Lapin delivers the complete solution from start to finish.
Problems We Solve
Common Backflow Preventer Installation Problems We Fix
Here are the issues our team commonly finds and resolves during backflow preventer installation calls across Central Florida.
Irrigation System Cross-Contamination
Lawn irrigation systems connected to the potable water supply without proper backflow protection can draw fertilizers, pesticides, and soil bacteria back into drinking water during pressure drops. This is one of the most common and preventable backflow hazards for Florida homeowners and commercial properties with landscaping systems.
Missing or Non-Compliant Devices on Commercial Properties
Florida and many local municipalities require backflow prevention devices on commercial plumbing connections including grease trap lines, fire suppression systems, and irrigation feeds. Properties without compliant devices face failed inspections, permit holds, and potential fines — issues that can halt business operations and construction timelines.
Outdated or Deteriorated Backflow Preventers
Backflow preventers contain internal components — springs, seats, and rubber checks — that degrade over time. An aging device may pass its annual test one year and fail unexpectedly the next, leaving your system unprotected. Proactive replacement of worn devices eliminates the risk of contamination and keeps you ahead of compliance deadlines.
Incorrect Device Type for the Application
Not all backflow preventers are equal. A pressure vacuum breaker (PVB), reduced pressure zone (RPZ) assembly, and double check valve (DCV) each serve different hazard levels and installation environments. Installing the wrong type is a code violation and may leave your system inadequately protected — a costly mistake that requires removal and reinstallation.
Failed Annual Backflow Testing
Florida requires annual testing of backflow prevention assemblies by a certified tester. A failed test means the device is no longer protecting your water supply and must be repaired or replaced promptly to restore compliance. Many property owners discover a failing device only when they receive a notice of violation — by then, the window to avoid penalties is already closing.
When to Call
Signs Your Plumbing System Needs Professional Attention
If you notice any of these warning signs, schedule backflow preventer installation before the problem becomes more disruptive or expensive.
You Have an Irrigation System or Pool Connected to City Water
Any landscape irrigation system, pool fill line, or decorative water feature connected to the potable water supply requires a backflow preventer under Florida law. If yours was installed without one — or the existing device is aging — contact Lapin to assess and correct the installation before your next inspection or permit renewal.
You Are Building or Expanding a Commercial Property
New construction and major renovations in Central Florida require backflow prevention devices as a condition of plumbing permits and certificate of occupancy. Getting the right device specified and installed correctly from the start prevents costly rework and keeps your project on schedule.
You Received a Notice of Violation or Failed a Plumbing Inspection
A notice from your municipality or water utility about a missing or non-compliant backflow preventer requires prompt action. Lapin Services can assess your system, install the correct device, and provide the documentation you need to clear the violation and restore compliance quickly.
You Notice Discolored Water, Unusual Taste, or Odors
Sudden changes in water color, taste, or smell can be a symptom of backflow contamination entering the supply line. While multiple factors can cause these issues, a compromised or absent backflow preventer should be ruled out immediately. Lapin's technicians can inspect and test your system and recommend the right corrective action.
Your Backflow Preventer Is More Than 10 Years Old
Even a device that passes annual testing may be nearing the end of its reliable service life after a decade of use. Upgrading an aging backflow preventer before it fails avoids emergency repairs, compliance gaps, and the inconvenience of an unplanned shutdown. Lapin can evaluate your current device and advise whether replacement now is the smarter investment.

FAQs
Backflow Preventer Installation FAQs
Is a backflow preventer required on my property in Orlando?
In most cases, yes. Florida state law and local ordinances require backflow prevention devices on all irrigation systems, commercial plumbing connections, and any cross-connection between potable water and a potential contamination source. Residential properties with lawn irrigation, pools, or other non-potable water connections typically require a device. Lapin’s technicians can assess your specific setup and confirm what is required for your property and municipality.
What types of backflow preventers does Lapin install?
We install all common backflow prevention assemblies used in residential and commercial applications, including pressure vacuum breakers (PVB), reduced pressure zone (RPZ) assemblies, double check valve assemblies (DCV), and atmospheric vacuum breakers (AVB). The correct device depends on the hazard level of the connection, local code requirements, and the installation environment. We assess your system and recommend the right solution for your application.
How long does a backflow preventer installation take?
Most residential backflow preventer installations are completed in two to four hours. Commercial installations or projects requiring significant piping modifications may take longer. After our initial assessment, we provide a clear timeline so you know exactly what to expect before we begin.
Does my backflow preventer need to be tested every year?
Yes. Florida requires that backflow prevention assemblies — specifically RPZ and DCV devices — be tested annually by a certified backflow tester to confirm they are functioning correctly. Lapin Services provides backflow testing and can set you up with a recurring annual schedule so you never miss a deadline or fall out of compliance.
Will I need a permit for backflow preventer installation?
Permit requirements vary by municipality and the scope of work. Many backflow preventer installations in Central Florida do require a permit, particularly for commercial properties and new construction. Lapin handles the permitting process on your behalf — we pull the permit, complete the installation to code, and provide all required documentation so you are fully covered.
What happens if my backflow preventer fails its annual test?
A failed annual test means the device is no longer adequately protecting your water supply and must be repaired or replaced to restore compliance. Lapin Services handles both backflow preventer repair and replacement. If your device fails, contact us promptly — we assess the condition, advise whether repair or replacement is the right call, and complete the work quickly so you can pass re-testing and resolve any compliance notices.
How much does backflow preventer installation cost in Orlando?
Cost depends on the device type, installation location, and any required piping modifications or permits. Residential installations are typically less involved than commercial or industrial applications. Lapin provides honest, upfront pricing before any work begins — no surprises. Call us at (407) 326-3367 or request a quote online to discuss your project and get an accurate estimate.
Can Lapin replace an existing backflow preventer that is worn or failing?
Absolutely. Lapin Services replaces aging, damaged, or non-compliant backflow preventers with correctly sized, code-compliant units. We assess the existing installation, recommend the right replacement device, and handle the full swap — including any necessary piping adjustments and post-installation testing — so your system is protected and compliant from day one.
