Frequently asked questions
How often is backflow testing required in Garden Grove?
In Garden Grove, most backflow prevention devices, especially for commercial properties and irrigation systems, require annual testing and certification to ensure they are functioning correctly and to maintain compliance with local water district regulations.
What is the difference between an RPZ and a PVB?
An RPZ (Reduced Pressure Zone) assembly is designed for high-hazard applications and provides the highest level of protection against backpressure and backsiphonage. A PVB (Pressure Vacuum Breaker) is used for low-hazard applications and primarily protects against backsiphonage.
Do I need a backflow preventer for my irrigation system?
Yes, in Garden Grove, nearly all irrigation systems are required to have a backflow prevention device installed. This prevents fertilizers, pesticides, and other contaminants from your lawn from entering your home's or the municipal water supply.
What happens if my backflow preventer fails the test?
If your backflow preventer fails its annual test in Garden Grove, it indicates a malfunction that could compromise water safety. Our technicians will diagnose the issue, perform necessary repairs or recommend replacement, and retest the device until it passes certification.
