What is a cross-connection?

Cross-connections potentially enable other (non-drinking) water sources of unknown quality to co-mingle with the public water system. Our backflow prevention program identifies and prevents cross-connections. A backflow prevention device will be required if a potential for cross-connection exists.

If your home water system is connected to a source of water other than your water supply - a cross-connection has occurred. "Indirect" cross-connections may occur by garden hoses and temporary connections that may be connected for only a few minutes. Direct cross-connections are more permanent hard-pipe arrangements.
