Water systems are designed to move water in one direction. A drop in pressure or a break in a water line can make the water flow in the opposite direction. This can draw contaminants like fertilizers and other chemicals into the drinking water system. This reversal of flow is called backflow or back siphoning. Contaminated water from the backflow can cause sickness or death.
A backflow prevention device, or assembly consists of a pair of check valves which shut when there is a reverse flow in the water line. So that the contaminants are kept out of the water system.
It is the responsibility of the supplier of water to prevent water from unapproved sources or any contamination from entering the public water system.
Water systems are devised to push water in one direction. A drop in pressure or a difference in a water line can make the water flow in the reverse direction. This can bring contaminants like fertilizer and other substances into the drinking water. This withdrawal of flow is described as the backflow or back siphoning.
Contaminated water from the backflow can generate sickness or also could lead to death. A backflow restriction device or arrangement consists of a set of control valves which shut when there is a backward flow in the water line. So that the contaminants are put out of the water system.
It is the obligation of the supplier of water to block water from unauthorized sources or any impurity from infiltrating the public water system.
