What affects the cost of Backflow Prevention & Testing
Frequently asked questions
How often is backflow testing required in Riverside?
In Riverside, backflow prevention assemblies are typically required to be tested and certified annually by a licensed backflow tester.
What is the difference between an RPZ and a PVB?
An RPZ (Reduced Pressure Zone) assembly is designed for high-hazard applications and can protect against both backpressure and backsiphonage, while a PVB (Pressure Vacuum Breaker) is for low-hazard applications and only protects against backsiphonage.
What happens if my backflow device fails its annual test?
If your backflow device fails its annual test, it will need to be repaired or replaced by a certified technician, and then retested to ensure it is functioning correctly and in compliance with Riverside regulations.
Do I need a backflow preventer for my irrigation system in Riverside?
Yes, in Riverside, irrigation systems are considered a potential cross-connection hazard and typically require an approved backflow prevention device, such as a PVB or RPZ, to protect the potable water supply.
