Got a Notice From Your Water District? What It Means and What to Do
A backflow notice is not a violation. It is a reminder that a device on your property needs its yearly test. Backflow is water flowing the wrong way, which can pull contaminants from a lawn, a boiler, or a drain back into the drinking water system. The device prevents that, and the test proves it still works.
Irvine Ranch Water District runs a backflow program with more than 17,000 assemblies in its service area, and it notifies customers when they need an assembly. The district asks for approved, testable assemblies on lawn irrigation systems and at the home's water service connection. El Toro Water District and Trabuco Canyon Water District run their own programs, so follow the notice you received.
Missing the deadline has consequences. Under the state's cross-connection rules, districts can issue shutoff notices to customers who do not have a required assembly tested on time. Read the due date on your notice and schedule the test before it passes.
Backflow Assembly Types and Where They Are Used
| Assembly | Typical use | What to know |
|---|---|---|
| Pressure vacuum breaker (PVB) | Lawn irrigation systems | Installed above the highest sprinkler, and tested every year |
| Double check valve assembly (DCVA) | Lower-hazard commercial services and some fire lines | Two check valves in series, tested every year |
| Reduced pressure principle assembly (RP) | Higher-hazard services such as restaurants, medical, and chemical use | Includes a relief valve that may discharge, so it needs drainage |
| Atmospheric vacuum breaker | Some hose connections and fixtures | Not testable and not for continuous pressure |
The district decides which assembly a property needs, based on the level of hazard.
Who Can Test and Who Sets the Rules
State drinking water rules, in Title 17 of the California Code of Regulations, require a certified tester to test backflow assemblies every year. In the Irvine Ranch Water District area, the Orange County Health Care Agency approves the testers and keeps a list. A test by someone not on that list does not count.
The assembly must be an approved model too. Approval comes from the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California, and districts only recognize assemblies that passed.
Ask any tester for their name and certification before the test, and confirm the district will accept the report. The tester submits the test and maintenance report to the district, and you should receive a copy. For commercial properties, see plumbing for commercial properties.
How an Annual Backflow Test Works
New assemblies are installed to the California Plumbing Code, which is built on the Uniform Plumbing Code (UPC), and every assembly is tested to the district's procedure.
Locate and clear
The tester finds the device and checks access around it.
Test
The tester connects a calibrated gauge set and tests the check valves and relief valve.
Repair if it fails

Backflow in Lake Forest: Irrigation, Associations, and Businesses
Most residential backflow devices here protect lawn irrigation. If your yard has a sprinkler system connected to the house's water, there is probably a vacuum breaker on it that needs a yearly test. An irrigation leak can also push your usage above budget, which is covered under finding the leak.
Associations manage common-area irrigation in the planned communities of Foothill Ranch, Portola Hills, and Baker Ranch. If the notice is for common area, the association is responsible, so forward it to your manager.
Food businesses and offices at Foothill Ranch Towne Centre and the business parks often have higher-hazard assemblies and may also have fire line devices. Those need the same annual test, and a failed one needs repair before the water district will accept the report.
What Affects the Cost of Backflow Testing
Insurance does not cover testing. The cost is a yearly compliance expense, and repairs after a failed test are separate.
