5 Essential Steps to Repair a Failed Backflow Device and Avoid a Water Shutoff
Getting a letter from the county about your water service is rarely good news. If you live in Manatee or Sarasota County, that letter often mentions one thing: your backflow preventer. Specifically, it might be telling you that your device failed its annual inspection.
At Accurate Backflow & Plumbing, we’ve seen these letters cause plenty of stress for local homeowners. Whether you’re in Bradenton, Lakewood Ranch, or Sarasota, the rules are clear, and the stakes are high. If you don’t handle a backflow preventer repair within the county’s timeline, your water service can be shut off and locked.
Nobody wants to deal with a dry tap on a hot Florida afternoon. To keep your water flowing and your property in compliance, here are the five essential steps you need to take after a failed test.
1. Understand the Failure (Why It Matters)
The first thing you need to know is that a failed test isn’t just a paperwork issue; it’s a safety issue. Your backflow preventer is the only thing standing between your home’s clean drinking water and potential contaminants like fertilizers, pesticides, or stagnant pool water.
In our 20+ years of serving this community, we’ve found that most failures happen because of worn-out rubber seals, debris trapped in the check valves, or spring fatigue. When these components fail, the device can no longer guarantee that water won’t flow backward into the public supply. Because this is a public health concern, Manatee County Utilities is very strict about their deadlines. Usually, you have just 30 days to complete your backflow preventer repair before they take further action.
2. Review the Official Failure Report
When a certified tester checks your device, they don’t just say “it failed.” They provide a specific report that identifies which part of the assembly is leaking or losing pressure.
Before you call for service, take a look at that report. Is it the first check valve? The second? Or perhaps the relief valve? Having this information ready when you call a professional helps us prepare the right parts for the job. If you’re unsure how to read the report, don’t worry, most homeowners find it a bit cryptic. You can simply hand it over to us, and we’ll translate the “plumber-speak” into a clear plan of action.

3. Hire a Licensed and Registered Contractor
This is the most critical step. Not every plumber is authorized to perform backflow testing in Manatee County or Sarasota County. To clear your failure notice, the work must be done by a contractor who is:
- Fully licensed and insured.
- Backflow certified.
- Registered with the specific county’s Cross Connection Control office.
At Accurate Backflow & Plumbing, we are the highest Google-rated backflow provider in the area. We maintain all the necessary certifications to ensure that once we finish your backflow preventer repair, the county will accept the results. Using an unregistered “handyman” for this task is a recipe for a water shutoff, as the county simply won’t recognize their work.
4. The Repair vs. Replacement Decision
Once we’re on-site at your Bradenton or Sarasota property, we’ll determine if a simple backflow preventer repair is enough or if a full replacement is necessary.
Most of the time, we can “rebuild” the internal components. This involves replacing the rubber gaskets, O-rings, and springs inside the brass body. It’s a cost-effective way to bring the device back to life. However, if the brass body itself is cracked or pitted from years of Florida sun and hard water, a replacement is the safer, more reliable option. We always provide upfront, transparent pricing so you can decide which path fits your budget best.
5. Re-Testing and Final Certification
The job isn’t finished when the wrench is put away. After any backflow preventer repair, the device must be re-tested to prove it is now functioning within the required parameters.
Once it passes, we submit the passing certification directly to the county for you. This “closes the loop” and prevents that dreaded water shutoff notice from progressing. We recommend keeping a copy of the passing report for your own records, just in case there’s a clerical mix-up at the utility office.

Frequently Asked Questions
How long do I have to fix a failed backflow preventer? In Manatee County, you typically have 30 days from the date of the failure notice to complete the backflow preventer repair and submit a passing test report.
Can I perform a backflow preventer repair myself? No. County regulations require that repairs and testing be performed by a certified backflow technician registered with the local utility department to ensure public water safety.
Will the county really shut off my water? Yes. If you ignore the initial failure notice and the subsequent final notice (which often gives only a 7-day warning), the county will send a crew to shut off and lock your water meter until compliance is met.
