The Importance of Backflow Testing & Why It Must Be Treated Seriously
Backflow is the unintended reversal of water flow through a cross-connection, created by a loss of pressure in the potable water distribution system which may create a serious health hazard. An appliance capable of creating more pressure than the public distribution system, such as a car wash operation, can cause a backflow of hazardous chemicals into the potable distribution system. The common lawn irrigation system can also allow the backflow of contaminated water back into the potable distribution system if the pressure is lost in the distribution system due to a main line breakage. Any backflow of water into the public water system can contaminate the water and make the water unsafe to drink.
