A cross-connection is a point in a plumbing system where it is possible for a nonpotable substance to come into contact with the potable drinking water supply.
Common examples of cross-connections include:
Most cross-connections occur beyond the customer service connection, within residential, commercial, institutional or industrial plumbing systems.
Identifying cross-connections can be challenging because many distribution systems are expanding to serve new customers and changing to accommodate customer needs. Further, temporary and permanent cross connections can be created in existing facilities without the knowledge of the water system managers and operators.
Backflow is any unwanted flow of used or nonpotable water, or other substances from any domestic, industrial, or institutional piping system back into the potable water distribution system. The direction of flow under these conditions is opposite to that of normal flow and is caused by either back-siphonage or back-pressure:
Outside water taps and garden hoses tend to be the most common sources of cross connection contamination at home. The garden hose creates a hazard when submerged in a swimming pool or when attached to a chemical sprayer for weed control. Garden hoses that are left lying on the ground may be contaminated by fertilizers, cesspools, or garden chemicals.
The Abington/Rockland Joint Water Works is continuously jeopardized by cross connections unless appropriate valves, known as backflow prevention devices, are installed and maintained. We continually survey all industrial, commercial and institutional facilities in Abington and Rockland to make sure all potential cross connections have been identified and eliminated or properly protected by a backflow prevention device. We also inspect and test each backflow preventer to make sure that it is providing maximum protection.
