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.
The problem of backflow is caused by what is commonly known as back pressure. Water remaining in the pipes after the system is shut off runs back into the pipes. This creates the opportunity for contaminants to enter the public water system. Most businesses are legally bound to install these devices prior to opening the doors for customers. There are several systems available and they must be inspected by certified professionals yearly as well as at the time of installation.
This is especially true if chemicals are introduced into water for pest control or fertilization of the crops. Sprinkler systems generally come with a shut-off valve but this is an inadequate answer to the problem because valves tend to leak causing the opportunity for potentially hazardous or toxic conditions. Most states have laws that demand that these devices be installed.
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 easiest whole system device to install is the pressure vacuum breaker assembly. It's also the least expensive and the most popular of all of the systems. It comes with an anti freeze function that protects the device itself. Since the lines are underground it does not need to protect the pipes attached to it. Another aspect of this device is that it frequently ejects water from its system and needs to be placed in a well drained area.
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.
There will be many decisions for you to make when selecting which irrigation backflow installation you want. You must determine whether or not you plan to use additives in the water you use. You must also consider size of project and the use of the project you are considering. The main objective needs to be the safety of everyone's water supply in the area and how to make certain that you do not contribute any contaminants to the area.
