Thanks to a backflow prevention device, contaminated water does not flow into our drinking water; therefore, every home and every commercial site must have a backflow prevention device installed. Contaminated water flows into our drinking water due to a pressure called a backflow. This pressure occurs when there is an unequal pressure in a pipe that is when the downstream pressure is greater than the pressure of the main water supply pipe, or when there is a stoppage of water supply due to a fire hydrant. Apart from this, backflow occurs in an irrigation system, a boiler, and a sprinkler of our homes. With the passage of time, the internal parts of a backflow prevention device, such as a gasket, a spring, and an O-ring may wear out. Therefore, for the well-being of other people and ourselves, we must test a backflow prevention device every 12 months for its physical and functional integrity. Testing a backflow prevention device means in eventuality keeping our drinking water free from chemicals, fertilizers, toxins, and pet waste. This means protecting ourselves from serious health problems. If the water that we have been drinking tastes different, then it is to be understood that time has come for a backflow testing. In the city, where we live, who knows the testing of a backflow prevention device better than a licensed plumbing company? It is the only dependable medium who can test a backflow accurately for us.
