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