Professional Backflow Prevention & Testing in Orange County

Backflow prevention is a legal requirement for commercial properties in Orange County. Backflow occurs when contaminated water flows backward into the clean water supply, posing serious health risks. Every commercial property with an irrigation system, fire sprinkler system, or connection to potentially hazardous equipment must have certified backflow prevention devices that are tested annually.

KCB Plumbing provides certified backflow testing, installation, and repair services for commercial properties throughout Orange County. Our technicians hold the required backflow tester certification and submit test reports directly to your local water district on your behalf. We make compliance simple and stress-free.

Missing your annual backflow test can result in fines, water service shutoff, or both. We track testing schedules for our commercial clients and send reminders when testing is due, so you never miss a deadline. We can also be your go-to for new device installations when adding irrigation or fire systems.

Common Questions

Backflow Prevention & Testing FAQ

How often is backflow testing required?

Most Orange County water districts require annual testing of all commercial backflow prevention devices. Some high-hazard installations may require more frequent testing. We track your schedule and notify you when testing is due.

What happens if my backflow device fails the test?

If a device fails, it needs to be repaired and retested. Common failures include worn seals, debris in the check valves, or relief valve issues. Most repairs can be completed on-site the same day, and we retest immediately after the repair.

What types of backflow devices are there?

The three most common types are Reduced Pressure Zone (RPZ) assemblies, Double Check Valve Assemblies (DCVA), and Pressure Vacuum Breakers (PVB). The required type depends on the degree of hazard — RPZ for high-hazard connections, DCVA for low-hazard, and PVB for irrigation systems.

Can you install new backflow prevention devices?

Yes, we install all types of backflow prevention devices for new connections, renovations, or upgrades required by your water district. We handle sizing, installation, initial testing, and all paperwork.
