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.
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 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.
For commercial properties the industry standard is the reduced pressure zone assembly. You will find these at apartment buildings and condominiums because they are the most efficient method of prevention against pollutants and toxins. They are the most complex and difficult to install but by far the most efficient means of protection. You may also find this type of assembly at major factories and businesses that use large amounts of water that may become contaminated from chemicals or other pollutants.
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 are many choices to make when choosing a backflow installation system for your project. The size of area, the option of adding chemicals to the water, the amount of water pressure needed are just a few. The main goal behind your decision should be the safety of the population served by the water source you are using. By investigating and choosing the highest form of protection for your system you can assure that your neighbors will not be affected by leakage from your system.
