Property owners in Blythe 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.

What affects the cost of Backflow Prevention & Testing
Frequently asked questions
How often do backflow devices need to be tested in Blythe?
In Blythe, 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 Blythe.
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.
What happens if my backflow device fails its test?
If your backflow device fails its test, it must be repaired or replaced promptly by a certified technician. The Blythe Water Department will require a retest to ensure compliance and prevent potential water contamination.
