Frequently asked questions
How often do backflow devices need to be tested in Calimesa?
In Calimesa, 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 Calimesa.
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.
