Backflow Testing: Keep Your Florida Property Safe and Compliant
Clean, safe water isn’t something you should ever have to second-guess. But even with a reliable backflow prevention system in place, it’s important to confirm that it’s doing its job. That’s where backflow testing comes in — a vital inspection that ensures your plumbing system keeps contaminants out of your drinking water.
At Griggs Plumbing, we provide certified backflow testing services for homeowners and businesses across Sarasota, Bradenton, and Lakewood Ranch. Our goal is simple: keep your water safe, your property compliant, and your plumbing system running smoothly all year long.
What Is Backflow Testing?
Backflow testing is a professional inspection that verifies whether your backflow prevention device is operating correctly.
During a test, a licensed plumber uses specialized gauges to measure water pressure and confirm that water is flowing in the right direction — away from your clean water supply.
Your backflow preventer acts as a one-way gate between your property’s plumbing and the public water supply. It stops contaminated water — from irrigation systems, fire sprinklers, or industrial plumbing — from flowing backward into your drinking water lines.
Testing ensures that the protective barrier is still working correctly and your water remains safe for use.
Why Annual Backflow Testing Is Required in Florida
In Florida, backflow prevention isn’t optional — it’s required by law. According to the Florida Administrative Code (§ 62-555.360), every public water system must have a cross-connection control program to prevent contamination.
Local utilities enforce these requirements through annual backflow testing mandates:
Regular testing doesn’t just meet legal requirements — it protects your home, business, and the health of your entire community.
Residential vs. Commercial Backflow Testing
While the purpose is the same — preventing contamination — residential and commercial systems differ in size, complexity, and testing requirements.

Commercial properties often include multiple devices and larger pipe systems, making testing more time-intensive. In most cases, the results must also be submitted directly to the local utility department for approval.
What Happens During a Backflow Test?
A standard backflow test typically takes between 30 and 60 minutes. Here’s what to expect when you schedule your inspection with Griggs Plumbing:
- Visual Inspection: The plumber checks for leaks, corrosion, or damage around your backflow assembly.
- Pressure Differential Testing: Specialized gauges measure water pressure at each valve to ensure correct direction and performance.
- Calibration or Cleaning: If needed, the technician cleans and adjusts the device for optimal operation.
- Reporting: Certified results are submitted to your local utility, ensuring your property stays in full compliance.
If your system doesn’t pass the test, our team explains the problem clearly and provides fast, cost-effective solutions — from small repairs to full device replacement.
Signs You May Need Backflow Testing Sooner
Even if your annual inspection isn’t due, some warning signs may indicate your backflow preventer isn’t working correctly. Schedule a test right away if you notice:
These can be signs of contamination or device failure — both of which require immediate attention from a certified Sarasota backflow testing expert.
What Does Backflow Testing Cost?
Pricing varies depending on property size, the number of devices, and accessibility. Based on average Manatee and Sarasota County rates:
Some small residential systems may cost as little as $75, while complex setups — like multi-unit buildings, irrigation systems, or fire suppression lines — may exceed $600.
If your system requires repairs or retesting, costs may increase slightly, but proper maintenance can prevent expensive replacements in the future.
💡 Tip: Regular plumbing maintenance helps prevent costly failures during your annual backflow testing.
