What is a cross connection?
Cross connections are connections between drinking water and other water or fluids of unknown quality. When that occurs, the drinking water supply can become contaminated during a backflow condition. Irving’s backflow prevention program, required by the State of Texas, is designed to identify and prevent cross connections.

A backflow preventer may be required if water or fluids of unknown quality co-exists on the same property with drinking water. Indirect cross-connections are made by garden hoses and temporary connections that may be connected for only a short time. Direct cross-connections are permanent hard pipe installations.
