A backflow preventer is a device that is used in many irrigation systems. It is designed to effectively allow water to flow in one direction, but prevents the water from flowing in the opposite direction. This important tool is necessary to keep unsafe water from reversing its flow and contaminating the clean water supply. In short, practically every irrigation system should have a backflow preventer.
How Does A Backflow Preventer Work?
A backflow preventer works by serving as a “one-way gate” for water. The device might be as simple as a single check valve that closes when the water flow begins to reverse. With this in mind, it is important to note that a simple check valve is not always the most reliable of solutions. Think of the simple check valve as the turnstile at a store entrance. The smallest amount of force or effort will overwhelm it, causing it to fail when it is needed most.
On the other hand, an elaborate backflow preventer can be a complicated device that is made-up of the following parts: check valves, air vents, water release valves, and testable systems. This type of backflow preventer is akin to an airport exit security checkpoint with one-way doors and an armed security guard who prevents travelers from exiting and reentering.
When Do You Need to Use A Backflow Preventer?
As mentioned previously, a backflow preventer should be used on almost every irrigation system. However, it is especially necessary when the water is coming from a potable source. In fact, in many areas, if your water comes from a potable source, then it is illegal to not have the correct local authority-approved backflow preventer on your irrigation system. If your water source is non-potable, then you legally might not be required to use a backflow preventer with your chosen irrigation system. However, many irrigation experts still recommend the use of a backflow preventer to “be on the safe side.” To determine if your irrigation system legally requires a backflow operator you should talk to a local authority before the installation of your system is completed.
In conclusion, a backflow preventer is an important device that can help protect the health of your water.
