Backflow is the undesired reversal of water flow against normal direction. Backflow occurs as a result of back pressure or back siphonage.

Back pressure occurs if the pressure in a private water system is greater than the pressure in the municipal water supply system. Back siphonage occurs when the pressure in the water supply system is lower than a private systems pressure. This can result in the reversal of flow between the public and private system.

A backflow prevention device is used to protect the potable water system from contamination or pollution due to backflow. Points at which a potable water system connects with a non-potable water system are called cross connections.Backflow means the undesirable reversal of flow of a liquid, gas or solid into the potable water supply.

Backflow preventers are devices with many working parts and annual testing ensures that the device is working effectively.
