What is a Backflow?
Normal water flow goes from the City's pressurized water supply system to the consumer's plumbing system. Backflow is the reversal of the normal direction of flow. Backflow may occur due to either back siphonage or back pressure.
What happens after backflow occurs?
When backflow occurs, any contaminants that had a chance to enter the water supply will start to flow towards any point of use (plumbing fixtures inside the building, other businesses/buildings connecting to the water supply system). The degree of hazard to health is dependent on the type and amount of contaminant, the situation of water use points, whether or not a protective device is in place, etc.
