Yes, we guarantee all backflow preventer repairs for a full 12 months, and if your work fails the re-test, we return at no charge to correct the problem until it passes. This isn't a conditional promise—it's backed by our 19 years of experience in plumbing systems and our commitment to work done to code.
Every backflow preventer repair we perform includes on-site testing before we leave your property. This means you're not waiting for a third-party inspector to discover problems; we've already verified the repair meets code requirements. The double-check valve, relief valve, or check cartridge we replace gets tested under actual water pressure conditions to confirm proper operation. If there's any doubt about performance, we address it immediately rather than scheduling a follow-up appointment.
The one-year guarantee covers all internal components we service, including the check cartridge, relief cartridge, and seals on double-check valves and reduced pressure principle (RP) devices. Whether we're repairing a residential backflow preventer on a lawn irrigation system or a commercial reduced pressure assembly protecting a building's domestic water supply, the same standard applies. If the device fails the official re-test conducted by your local water authority, we dispatch a technician at no cost to diagnose and repair the issue.
This guarantee exists because backflow prevention failures are serious. A failed backflow preventer can allow contaminated water to flow backward into your municipal water supply, creating public health risks and regulatory violations. Most jurisdictions require annual backflow testing and certification, often through the American Backflow Prevention Association (ABPA) standards. When a device fails, you're facing potential fines, water service restrictions, or mandatory replacement—costs that quickly exceed the original repair investment.
Our guarantee reflects confidence in the parts we use and the workmanship our licensed plumbers deliver. We're an authorized Generac and Noritz dealer, which means we maintain relationships with quality manufacturers and stay current on the latest equipment standards. That same commitment to quality extends to backflow preventer repairs, where we source certified replacement cartridges and components that meet or exceed manufacturer specifications.
Real-world scenarios support this guarantee. A homeowner with a failed check cartridge gets the component replaced, tested on-site, and a written guarantee that covers the repair. If the water authority's re-test identifies an issue weeks later, we're back out—no service call fee, no parts markup, no questions asked. This approach eliminates the frustration of being caught between a failed inspection and repair bills you weren't expecting.
We test every repair before leaving your property because workmanship matters. You get the backflow preventer working correctly the first time, documented proof it passed testing, and the security of our one-year guarantee backing that work.
Blackmon Plumbing provides licensed backflow preventer repair and testing throughout the service area, with same-day emergency dispatch available for failed devices requiring immediate correction.
