  Backflow is defined as the flow of non-potable water (unsuitable drinking water) or other liquid, solid or gas into the distributing pipes of a potable water supply because of an unwanted reverse flow, back-siphonage or back pressure. This could allow contaminants that could be in the water to flow back into the potable water, putting the public at risk.
