Backflow devices are designed to protect the potable water supply from contaminants returning up the water lines from back-siphoning or back-pressure. They are very important for protecting the public water supply from potential health hazards. There are several different types of backflow installation devices to choose from when designing your new system. All of these systems must be inspected every year to assure that they are working properly.
Backflow is a problem because anything in the pipes you are using can be sucked back into the neighborhood water supply. The water is moved by back-pressure and is a fairly common occurrence. Most businesses are required by law to install the devices to protect the water supply.
With irrigation systems it's very common to introduce fertilizers and pesticides to water to enhance the growth of the crops. Most sprinkler systems have shut off valves that are used after the watering process is complete. The issue with these valves is that they can leak or break allowing water to flow back into the plumbing lines. When there are additives in the water they flow into the plumbing also. These devices serve to prevent this from happening.
A double check valve assembly is not approved for systems that plan to inject chemicals into the system. They are the most common of all inline underground systems. They are less apt to freeze in harsh weather because they are under the soil or in basements or out buildings.
The most common and least expensive type of whole-system preventive devices is the pressure vacuum breaker assembly. This system is the easiest to install of all whole system devices. Many of these have a freeze protection valve installed in them. Unfortunately it only covers the device not the pipes. Another drawback to this type of assembly is that it occasionally ejects water so installation inside a building needs to have proper drainage.
In apartment buildings and other commercial areas the preferred choice is the reduced pressure zone assembly. It is an industry standard for multiple residence and business sites because of the efficient way it protects against pollution and toxic substances in the water. These are the most complex of the assemblies available and the most difficult to install. This assembly is also used for factories that use water for their daily production.
For sheer simplicity the atmospheric vacuum breakers are the answer. They handle single lines of irrigation systems and you can use up to six of them on your property. These are also the least expensive of all of the assembly packages and can be easily installed as well. This package cannot be used for whole system operations.
Which backflow installation system to choose is a major decision when you are planning to begin irrigation of your land. What is appropriate will depend on many factors. In making up your mind you will take into consideration whether you plan to inject chemicals into your system or not, the amount of land you will be irrigating and the water pressure in the area will all have to be considered. One of the goals you will want to reach will be to protect the regional water supply by installing the best system available for your needs.
