Backflow is a reversal of the normal direction of water flow in a water supply plumbing system. It occurs when the water delivery main is at a lower pressure than the internal plumbing system, also known as back siphonage. Because of pesticides, fertilizers, and pet droppings, all irrigation water is considered high hazard. Because of this, there is a backflow event can be potentially serious nature. All irrigation systems connected to potable water in the State of Florida require a backflow prevention device. Most devices require testing once per year. B & R Industries, Inc. has employees that are certified by the American Society of Sanitary Engineers to test these devices and report their findings to the appropriate agencies.
