The cause of back flow can be back pressure or back siphonage. Back siphonage occurs when there is lower pressure in supply piping compared to private properties systems. breaks, repairs and firefighting activities can interrupt the main water supply causing back siphonage. Interruptions such as breaks, repairs and firefighting activities can cause back siphonage. Back pressure is caused by the pressure increase in private water systems. water borne diseases can affect children, elderly people and people with low immunity if they drink water that is contaminated by impurities from back flow.
