SOME FREQUENTLY ASKED QUESTIONS ABOUT BACKFLOW
Who is requiring the backflow device? There have been many documented cases of drinking water being contaminated or polluted, by both commercial and residential sources, around the world, The United States Department of Environmental Protection, Adopted the Safe Drinking Water Act in 1974(revised it in 1986 and 1996) Public Law 99-339. In Georgia the Cross-Connection Control regulations are set forth in The Georgia Rules for Safe Drinking Water Chapter 391-3-5-.13. This made it the responsibility of the local water purveyors to enforce the cross connection laws. To meet these Responsibilities, The State of Georgia now requires local municipalities to maintain backflow prevention programs.
What is backflow? Backflow is a water condition that you want to avoid at any cost. Simply put, backflow occurs any time the flow in your water system reverses. For example, occasionally a car will strike a fire hydrant on a street. Water will gush out of the hydrant at full water pressure, causing a huge drop in water pressure at all buildings on the block. With this drop of pressure, the direction of water flowing through pipes can actually reverse. Whenever flow reverses, there is a strong likelihood of fresh water contamination. With this in mind, you clearly want to avoid mixing fresh water with non-potable water. This is what a backflow valve is designed to prevent.
What is the purpose of a backflow prevention valve? The backflow prevention valve prevents contamination of the city’s water main.. Imagine, for example, you have a garden hose in a bucket of soapy water, The water pressure supplied to your property may drop unexpectedly. When this happens, the water flow to the water hose in the bucket of soapy water could reverse and suck the contents of the bucket into the city’s water main. When the water pressure is restored, the soapy water from the bucket can contaminate the City’s water main. Every building on your street could then have soapy water flowing out of their water faucets. Obviously, in industry, things could get even more extreme. Facilities that process Acids, toxic chemicals or sewage need to prevent a reversal of water flow at any cost. This is where a backflow valve comes in. During a time of water pressure fluctuation, the valve will prevent your facility’s materials from flowing into the city’s water system.
How often do I need to test my backflow device(s)? Most states and/or local municipalities require annual testing of backflow devices. A backflow assembly has test cocks and shut-off valves and must be tested each year, if relocated or repaired, and when installed.
How do I get my backflow tested, and how much will it cost?
