Backflow occurs when water that has already entered a facility flows back into the public water system. A cross-connection is a point in a plumbing system where drinking water becomes directly connected to water that is unfit for drinking.
There are two causes of backflow. One is called backsiphonage, while the other is back pressure. Backsiphonage is the reverse flow of water due to negative pressure. This occurs when water mains experience a sudden drop in pressure. Back pressure may occur when a heating system or elevated tank creates a bulge in your plumbing that exceeds water pressure.
