Backflow Replacement

When Backflow Replacement Is the Right Choice

Backflow assembly replacement becomes necessary when a device is beyond repair, no longer meets current code for its hazard level, or has reached the end of its service life. The Backflow Co supplies, installs, and tests replacement assemblies sized correctly for your application and local utility requirements.

Florida building codes and cross-connection control programs continue to evolve. An older device that passed testing for years may no longer be acceptable if your property's hazard classification has changed or if local standards now require a higher level of protection.

Types of Backflow Devices We Install

Selecting the correct device type depends on your cross-connection hazard level, installation location, and local code requirements. Our licensed installers recommend the appropriate assembly for each application.

• Double Check Valve Assemblies (DCVA) for low-hazard irrigation and fire line applications
• Reduced Pressure Zone (RPZ) assemblies for high-hazard commercial and industrial connections
• Pressure Vacuum Breakers (PVB) for irrigation systems above grade
• Spill-Resistant Vacuum Breakers (SVB) for limited hazard indoor applications

Our Replacement Installation Process

We evaluate your existing installation, confirm the required device type and size with your water utility if needed, and handle permit requirements where applicable. On installation day, we shut down water to the affected line, remove the old assembly, install the new device on code-compliant piping with proper clearances and support, and perform initial testing.

All replacement installations include the first certified test and electronic submission of results to your water provider. Most residential irrigation replacements are completed in a single visit.

Sizing and Code Compliance

An incorrectly sized backflow device can cause pressure drop problems, water hammer, or inadequate protection. We size replacements based on system flow requirements, pipe diameter, and the specific demands of irrigation zones, fire sprinkler systems, or commercial process lines.

Installations meet Florida Building Code, AWWA cross-connection control standards, and local utility installation requirements including proper above-grade mounting, freeze protection considerations, and accessible test cock orientation.

Residential and Commercial Replacement

From a single 3/4-inch irrigation backflow in a Lehigh Acres home to a bank of commercial RPZ assemblies at a Naples medical plaza, The Backflow Co handles replacements of every scale across Southwest Florida.

We work with homeowners, property managers, HOA boards, general contractors, and facility managers to minimize downtime and complete installations with minimal disruption to water service.
