What is backflow?

Backflow is the undesirable reversal of the flow of water from its intended direction in a pipeline or plumbing system. Backflow can occur when pressure is reduced in the distribution system due to a break in the main line, firefighting, or other distribution system situations. Backflow can allow contaminants to enter private plumbing systems and city water distribution systems.
