Selecting The Appropriate Irrigation Backflow Installation System

By Katy Kline


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 the reversal of water in the pipes and plumbing system. It is a common problem that is caused by back pressure. It can contaminate your water as well as water located in the main system. Most businesses are required to install preventive devices to stop water from flowing back into the plumbing.

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 pressure vacuum breaker assembly is probably the least expensive whole-system device available. It is also the easiest to install and many come with freeze protection devices in them. The freeze device only covers the assembly leaving pipes unprotected. The device also spurts water occasionally so it is best installed in an area that has good 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.

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.
