Why Backflow Prevention is Necessary.
The reversal of the water flow called backflow and causes the mixing of clean water with unwanted substances such as industrial water or dirty water. Conditions such as the decrease in public water systems may cause a back flow of water from private property such as swimming pools and irrigation schemes. The cause to pressure decrease could be a leak in the system. Water backflow that contaminate clean water can be prevented from getting back into public water supply pipes through the use of back flow prevention devices.
The cause of back flow can be back pressure or back siphonage. Pressure lower than that of private systems in supply pipes causes back siphonage. Back siphonage can happen when the main water supply is interrupted by breaks, repairs or firefighting activities. Pressure increase in private properties water systems causes back pressure. Dirty water from backflows can cause illnesses to children, people with low immunity systems and elderly people. There is nothing you can do about water backflow other than prevention using back flow prevention devices because its causes is beyond our control.
It is a requirement to install backflow devices and testing them on annual basis in most areas. It is important to occasionally test backflow prevention devices because they have no protection benefits if they are not installed well or are faulty. you can get fined for not installing back flow prevention devices in some counties. If you are in Santa Fe area of New Mexico USA, you can count on the backflow testing and repair companies such as Santa Fe back flow testing and Alberquequeback flow testing to for testing services.
It is the function of the backflow preventer to make sure that water flows in one direction. The different designs of the back flow preventer device include the double-check valve flow preventer and the reduced pressure zone backflow preventer. The air vets, water release valves and check valves make it easier for technicians and owners to check the function ability of the double check valve backflow preventer. Some backflow prevention devices can be easy to install but it is better to have the installation done by a licensed plumber.
There is a lot of emphasis to landscapers and irrigation businesses that are connected to main public water supply grid to have the installation of backflow prevention devices. Fatal results can be experienced if pesticides from irrigation businesses flow back into your household water supply contaminating the water that you use for household activities such as cooking and drinking. It is the responsibility of water supplying authorities and the local governments to protect drinking water by inspecting the bachflowprevention devices.
