The critical level marking on a backflowpreventer device, including but not limited to a vacuum breaker, is normally a horizontal line usually stamped on the device by the manufacturer, the location of which has been established by the manufacturer to conform the device to an accepted standard with the goal of having an approved installation of the device to ensure the proper functioning of the device for cross connection control protection purposes. When a backflowpreventer device does not bear a critical level marking, the bottom of the vacuum breaker, combination valve or the bottom of any approved backflow preventer device shall constitute the critical level.
Cross Connection - any physical connection or arrangement between two otherwise separate piping systems, one of which contains potable water and the other, water of unknown or questionable safety, whereby water may flow from one system to the other, the direction of flow depending on the pressure differential between the two systems. See backflow and back-siphonage.
