cross connections What is a Cross Connection? A cross connection is a point in a plumbing system where the potable water supply is con-nected to a non-potable source. Briefly, a cross connection exists whenever the drinking water system is or could be connected to any non-potable source (plumbing fixture, equipment used in any plumbing system).
