Backflow Replacement Services

When your backflow prevention device fails its annual test or reaches the end of its service life, professional replacement ensures your property stays compliant and your water supply remains protected. County Backflow specializes in seamless backflow preventer replacement for residential, commercial, and industrial properties across Southern California.

With over 30 years of experience and a licensed C-36 contractor designation, we handle every aspect of your replacement project—from initial assessment and device selection through installation, testing, and compliance documentation.

When Backflow Replacement Becomes Necessary

Understanding when to replace rather than repair your backflow preventer protects you from unnecessary costs and compliance issues. Replacement typically makes sense when:

Your device has failed multiple tests. Repeated failures often indicate internal component degradation that repair cannot fully address. When repair costs approach 50-60% of replacement cost, investing in a new device provides better long-term value.

The assembly is 15-20 years old. Even well-maintained backflow preventers experience wear over time. Older devices may not meet current code requirements, making replacement the only compliant option.

You've received a mandate for system upgrade. Water districts sometimes require property owners to upgrade to higher-level protection, such as replacing a double-check valve with an RPZ assembly.

The device sustained physical damage. Freezing temperatures, vandalism, or accidental impact can compromise the assembly beyond economical repair.

Professional Backflow Preventer Installation

Our comprehensive replacement service removes the administrative burden from property owners while ensuring code-compliant installation.

Complete Project Management

We coordinate every detail of your backflow replacement project. This includes conducting the initial site assessment, selecting the appropriate device for your application, obtaining necessary permits, scheduling water shutoff coordination with your district, and managing the installation timeline to minimize disruption.

Expert Device Selection

Not all backflow preventers suit every application. Our certified specialists evaluate your specific requirements—water pressure, flow rate, space constraints, and district regulations—to recommend the optimal device. We work with leading manufacturers to source assemblies sized from ½ inch for residential irrigation systems to 12 inches for large commercial and fire service applications.

Licensed Installation Standards

As a licensed C-36 plumbing contractor, County Backflow meets the highest installation standards. We ensure proper orientation, adequate clearances for testing and maintenance, appropriate drainage provisions, and protection from freezing where required. Our installations pass inspection the first time, eliminating delays and additional costs.

Testing and Certification

Every replacement includes comprehensive testing of the new assembly to verify proper operation. We submit all required documentation to your water district within mandated timeframes, ensuring your property maintains compliance without interruption of water service.

Backflow Replacement Cost and Timeline

Transparency in pricing helps property owners budget appropriately and make informed decisions.

Residential replacements for standard irrigation and domestic systems typically range from $2,000 to $5,000, depending on device type, size, and site conditions. Most residential projects complete within 4-6 hours, with water service restored the same day.

Commercial and industrial replacements vary significantly based on system complexity. Fire service backflow assemblies, large domestic meters, and specialized industrial applications can range from $3,000 to $50,000 or more. Complex commercial installations may require 1-3 days depending on coordination requirements and system size.

Several factors influence replacement cost, including the type and size of device required, accessibility of the installation location, permit and inspection fees, water shutoff coordination needs, and any necessary modifications to existing plumbing infrastructure.

We provide detailed written estimates that clearly outline equipment costs, labor, permits, and any site-specific requirements. No hidden fees, no surprises.

Types of Backflow Devices We Replace

Our expertise spans the complete range of backflow prevention assemblies.

Reduced Pressure Zone (RPZ) Assemblies provide the highest level of protection and are required for high-hazard applications. We install RPZ devices for fire protection systems, commercial kitchens, medical facilities, industrial processes, and irrigation systems with chemical injection.

Double Check Valve Assemblies suit moderate-hazard applications and are commonly used in residential irrigation systems, commercial buildings without high-hazard conditions, and multi-family residential properties.

Pressure Vacuum Breakers work well for irrigation applications and hose bib protection. These assemblies must be installed at least 12 inches above the highest downstream outlet.

Fire Service Backflow Assemblies protect public water supplies from fire protection systems. We specialize in large-diameter detector check assemblies and RPZ devices required for fire service lines.

Why Choose County Backflow for Replacement Services

Selecting the right contractor for backflow replacement impacts both immediate results and long-term satisfaction.

Since our founding, County Backflow has completed thousands of replacement projects across residential, commercial, industrial, and government properties. Our extensive experience means we've encountered and solved virtually every installation challenge. We bring this knowledge to your project, anticipating potential issues and implementing solutions before problems arise.

Licensed C-36 Contractor Credentials

Many backflow testing companies hold only tester certifications, limiting their ability to perform installation work. Our C-36 plumbing contractor license qualifies us for complex installations that basic testers cannot legally perform. This higher credential level demonstrates our commitment to professional standards and ensures your project meets all regulatory requirements.

Complete Compliance Management

We eliminate the administrative hassles of backflow replacement. Our team handles permit applications, coordinates with water districts, schedules inspections, files test reports, and maintains your compliance documentation. Property managers particularly appreciate this full-service approach, which allows them to focus on their core responsibilities while we manage every technical and regulatory detail.

Approved Across Multiple Water Districts

County Backflow maintains approved contractor status with water authorities across San Diego, Orange, Riverside, and Los Angeles Counties. This extensive approval network matters because some districts require pre-approved contractors for backflow work. Our established relationships with district officials also facilitate smoother permit processing and inspection scheduling.

The confidence placed in County Backflow by major commercial property managers speaks to our capabilities. We serve facilities for Amazon, Divisions Maintenance Group, and Sea Haven, handling everything from single-device replacements to large-scale projects involving multiple assemblies.
