Backflow happens when water flows in the opposite direction, allowing pollutants from a property to enter the clean water supply. This can introduce substances such as chemicals, bacteria, and other contaminants into what should be potable water. It’s a serious concern that requires proper prevention measures.
In the San Francisco and Bay Area counties, annual backflow testing is not optional—it’s a regulatory requirement. In line with the California Code of Regulations, Title 17, and local ordinances, any property equipped with a backflow prevention device must be tested each year. These evaluations must be completed by certified professionals to confirm compliance and system reliability.
