What is Backflow?

“Backflow” describes the unwanted reversal of the direction of flowing water. It is usually caused as a result of back pressure, which occurs when the pressure in a private water system is greater than the pressure in the municipal water system, or back siphonage, a problem caused by negative pressure in a water supply system that allows contaminated water to enter a potable water supply.
