For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
BACKFLOW. The undesirable reversal of water flow in a water system through a cross-connection. Water will always flow towards the point of lowest pressure. BACKFLOW can occur due to high pressure on the customer side, or low pressure in the city’s water system.
CROSS-CONNECTION. An actual or potential connection between a public water system line and any other pipeline, which contains water of fluids of a questionable or unknown source or quality. When this situation occurs, the drinking water system can become contaminated during a backflow condition.
