cross-connection (cross-con•nec•tion)

1. a physical connection or arrangement between two otherwise separate (piping) systems, one of which contains potable water and the other water of questionable or unknown safety: such as steam, gas, or chemicals. There may be a flow from one system to the other, the direction of flow depending on the pressure differential between the two systems. 2.
