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