Irrigation Backflow Preventer

Whether it’s for a residential or commercial irrigation system, it’s important to have a backflow preventer. The reason is because in most places, having an irrigation backflow preventer is required by law. However, even if you don’t live in an area that legally requires you to have a backflow preventer, it’s still a very good idea for you to have one. Most irrigation water contains contaminants like pesticide and waste. As a result, not having a backflow preventer can cause your irrigation water to harm yourself or others. Fortunately, you can avoid this very serious problem by simply adding a backflow preventer to your irrigation system.

When it comes to choosing a backflow preventer, there is no shortage of options available. In fact, there are four main types of backflow preventers. The four main types are an anti-siphon valve, pressure vacuum breaker, double check type backflow preventer and reduced pressure type backflow preventer. Because there are several different options available, you will be able to make your decision based on which type will work best for your needs and budget.

The first type of irrigation backflow preventer is an anti-siphon valve. This is the most common type of backflow preventer used for residential settings. Because it is the most common for this setting, it is also the most affordable of all four of the main types of preventers. When this type of backflow preventer is used, the valves are normally installed in groups. Whether you are installing it yourself or hiring someone to install it for you, it’s important to make sure that it’s not installed below the ground. If you need a residential backflow preventer and your biggest concern is price, an anti-siphon valve is probably the best choice for you.

The next type of preventer is a pressure vacuum breaker. The advantage of this type of backflow preventer is that only one is needed. While other preventers require multiple installations, this is not the case with this type of backflow preventer. If you choose to use this type of backflow preventer, it’s important to find out if there are any specific regulations for the area where you are installing it. In many places, regulations require that a pressure vacuum breaker is installed within eighteen inches of the water source connection. Keep in mind that this type of preventer can spit water. However, if you install a check valve, it will reduce or eliminate the water spitting.

Of all the types of irrigation backflow preventers, the most controversial is the double check type backflow preventer. This option is so controversial that it may not even be legal in your area. If it is legal in your area, the big benefit of this option is that it is less susceptible to freezing. However, if there is any chance of serious health hazards being present in your water, this is not the type of irrigation backflow preventer that you should use.

The last type of preventer is the reduced pressure type backflow preventer. This backflow preventer is ideal for situations where the water presents a significant health risk. Because of this fact, this type of preventer is most commonly used in commercial situations. In addition to being used for commercial irrigation, this type of preventer can be used for a wide variety of other purposes. This is why it’s common to see reduced pressure type backflow preventers in non-agricultural commercial business areas.

By understanding the unique features of each backflow preventer, as well as all the relevant regulations in your area, you will be able to choose the irrigation backflow preventer that will work best for you.
