What is Backflow?

Backsiphonage exists when there is a negative or sub-atmospheric pressure in the supply piping, allowing downstream substances to be siphoned into the potable water supply.

Backpressure conditions exist when a pressure higher than the supply is created in the downstream piping, allowing downstream substances to be pushed into the potable water supply.
Cross-connections are defined as any actual or potential connection between a potable water system and any other source through which a substance, other than potable water, may be introduced. Cross-connections constitute a potentially serious public health hazard as there are numerous, well-documented cases where they have been responsible for the contamination of drinking water, and have resulted in the spread of disease. For this reason, it is essential that all municipalities with public water supply systems develop and administer a comprehensive Cross-Connection Control Program.
