Frequently asked questions
How often do backflow devices need to be tested in Mecca?

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 Mecca.
