Every home is at risk of backflow, contaminating the water used for drinking, cooking, washing, and cleaning. Backflow is one of the easiest ways to contaminate the city water supply. Cross-connections characterize water systems and dirty water can bring pollutants to fresh, clean water. As such, backflow prevention devices are necessary to avoid incursion of foreign substances that may cause illness.
What are the two main causes of backflow?
Why does backflow happen? One of the two main causes is backpressure. When pressure from a household installation or appliance (like a heating system) increases the water system, the flow of water will start reversing. The second main cause is a phenomenon called backsiphonage. When there is a break in the mains, backflow may occur due to negative pressure. This may also happen during firefighting efforts.
