Backflow Prevention & Testing in Riverside
Backflow prevention involves installing and maintaining devices that stop contaminated water from reversing flow into your clean drinking water supply. Property owners in Riverside typically need this service annually, especially if they have irrigation systems, fire suppression systems, or commercial properties, to comply with local health regulations and protect public health.
This service is crucial for preventing the contamination of your potable water supply with pollutants or toxins, safeguarding the health of your family and community. Neglecting backflow prevention can lead to serious health risks, fines from the Riverside Water Department, and potential water shut-off until compliance is met.

Frequently asked questions
How often do backflow devices need to be tested in Riverside?
In Riverside, backflow prevention devices typically require annual testing and certification by a qualified technician to ensure they are functioning correctly and to comply with local regulations.
What types of properties require backflow prevention?
Commercial properties, multi-family residences, and properties with irrigation systems, fire suppression systems, or boilers are common examples of those requiring backflow prevention in Riverside.
What is the difference between an RPZ and a PVB?
An RPZ (Reduced Pressure Zone) assembly offers high-level protection against both backpressure and backsiphonage, suitable for high-hazard applications. A PVB (Pressure Vacuum Breaker) is for lower-hazard applications and protects only against backsiphonage.

If your backflow device fails its test, it must be repaired or replaced promptly by a certified technician. The Riverside Water Department will require a retest to ensure compliance and prevent potential water contamination.
