What is a Cross Connection?
According to the Canadian Standards Association, a cross connection is defined as any actual or potential connection between a potable water system and any source of pollution or contamination. Cross connections are present in every water system and, depending on the size of the system, hundreds or thousands of potential cross connections can exist. Wherever physical cross connections exist between a potable and non-potable water, there is the potential for backflow to occur.

Backflow is a flow of solid, liquid or gas from any source opposite to the normal direction of flow, back into the potable water supply or system. There are two types of backflows: back-siphonage and backpressure.
What is back pressure?
Caused whenever a potable system is connected to a non-potable supply operating under a higher pressure by means of a pump, boiler, etc. There is a high risk that the non-potable water may be forced into the potable system whenever these cross connections are not properly protected.

Cross connection control is defined as the enforcement of an ordinance regulating cross connections. Municipalities and other communities set up cross connection control programs that monitor the installation, maintenance and field testing of backflow preventers in accordance with local bylaws and other codes and standards.”
