What is a cross-connection, and why are they a problem?

A cross-connection is a connection between a drinking water pipe and a polluted source. A common example is if you were spraying weed killer on the lawn and the water pressure dropped. The chemical could be sucked back into the water pipes through the hose. Lawn irrigation systems and hot water boilers are examples of cross-connections that require backflow preventors.
