Backflow occurs when water exits the drinking water system , (potable water system), is exposed to poisons, and poisonous chemicals in the environment and then sucked back into the drinking water system through siphoning.
Examples
Places where backflow can occur in the house include the underground irrigation system, the indoor fire prevention sprinkler system, and the outdoor hose bib.
Preventing the Backflow
Backflow is prevented by devices called backflow prevention devices, which are installed in your flow system, and automatically block backflow, when they sense that the water is starting to move in the wrong direction.
