What Is Backflow Repair?
Backflow repair is the process of diagnosing and fixing a malfunctioning or failed backflow prevention assembly. A backflow device can fail for many reasons — worn internal components, corrosion, mineral buildup, freeze damage, or physical impact. When your assembly fails its annual test or is visibly damaged, it must be repaired before it can be retested and certified as compliant. Our certified technicians carry common repair parts for all major backflow assembly brands, allowing us to complete most repairs on the first visit without ordering parts. We diagnose the exact cause of failure, perform the repair, and retest the device on the same visit to confirm it passes. A passing test report is then filed directly with your water district.
Why It Matters
A failed or damaged backflow preventer poses a real risk to public water safety. Water districts require that any assembly failing its annual test be repaired or replaced before the property can be considered compliant. Ignoring a failed test can result in a notice of non-compliance from your water district and, in some cases, water service interruption. Timely repair by a certified technician protects your water supply, maintains your compliance status, and avoids costly shutoff fees. Southern California Backflow responds quickly to repair calls across the Inland Empire, often completing repairs same day.
Our Backflow Repair Process
Our technician tests the assembly to identify which component has failed — relief valve, check valves, or other internal parts.
We assess what parts are needed. In most cases, we carry the required parts on our service vehicle for common brands and models.
We replace the failed components using manufacturer-approved parts, restoring the assembly to proper working condition.
After repair, we retest the assembly to confirm it passes the pressure differential test and is functioning within required tolerances.
We file the passing test report with your water district on your behalf — same day in most cases.
