What Is Backflow?

Backflow Testing and PreventionAs the name implies, backflow is the reverse flow of waste water back into the clean water supply. Backflow can result in the contamination of the water supply, making drinking water unsafe to consume.

For backflow to occur, one of two conditions have to be present in the plumbing system – backpressure or back-siphonage. Backpressure happens when the downstream pressure in a water line is greater than the supply pressure. Back-siphonage is caused by a partial vacuum in the plumbing system. When the pressure in a system drops below 14.7 PSI (atmospheric pressure), it causes negative pressure, resulting in a siphon within the pipe.

Backflow can be caused by a number of conditions, including: high demand, such as when a fire hose is used down the line, a main line breakage, pump failure, or the collapse of a water column in an elevated line.

Backflow Prevention

To prevent backflow, plumbing systems employ different types of backflow assemblies and devices that work to prevent the water supply from flowing backwards. Some of these assemblies can be tested to ensure they are working correctly, while other devices, such as those used on outdoor hose bibs, cannot be tested. Because all plumbing systems eventually wear out, it's a good idea to have these systems inspected or tested to ensure they are working correctly.
