Backflow Information

Backflow Prevention
In accordance with current ordinances, the Building Inspection and Water Operation Departments are required to regulate the installation and testing of backflow prevention devices.

Backflow Definition & Prevention Device Information
These devices are designed to prevent the entry of harmful substances into the potable water supply. Contaminating or polluting substances may enter the potable water source when the pressure of the polluted source exceeds the pressure of the potable source. This action is called a backflow and is typically caused by a back-siphonage or backpressure. To assure safe water, it is essential that cross connections be eliminated from both the distribution system and the plumbing systems of buildings. Where elimination is impractical, protection by the installation of an approved backflow prevention device becomes necessary.

Prior to the installation of a new irrigation system, plumbing system or modification of a current plumbing system, please contact Development Services for information regarding required permits and plan review.
