What is “Backflow”?
Water used in residential and commercial spaces, such as plumbing, irrigation systems, or fire protection should only flow into the property in a single direction. A sudden pressure change can affect the main supply line causing water to trickle back in. For example, if a sudden change occurs, such as a water main break or nearby fire hydrant is in use, the system may lose pressure. The reduction in pressure in the pipeline no longer pushes water into the property in one direction. However, when water flows in the opposite direction, the water can contaminate the main water supply. Backflow is hazardous because it can contaminate public drinking water with impurities like fertilizers, pesticides, human waste, and toxic chemicals.
How is a Backflow Test Done?
The backflow test is performed to investigate if backflow particles are present in the current system so that the cause can be determined to repair the issue. A certified plumber will begin by inspecting the pressure of the system by attaching the backflow testing gauge, otherwise known as gate and relief valves. The plumber will close the downstream valve and wait a few minutes before checking for changes in the direction of movement of the pressure gauge as well as simultaneously check for water leaks and other obvious signs by closing different valves.
