What is Backflow Testing for an Irrigation System?

Irrigation backflow testing involves an annual inspection of the backflow preventer device that is required to prevent water from flowing back into your main water supply. This device is designed to protect against the contamination of potable water from non-potable sources, such as irrigation water. When this device is tested, a certified technician will make sure that it is connected and operating properly, measure the rate and pressure of the water, and test the device for cross-contamination. Upon a passing result, the results will be submitted to your utility’s online system (if applicable).

What are the most common problems with backflow preventers?

The most common problems we see with backflow preventers are corrosion, leaks, clogs, and improper maintenance. Over time, debris and sediment can build up in the backflow preventer, causing the value to malfunction or become clogged. In addition, not winterizing your irrigation system can allow water to settle into your backflow preventer, freezing and causing damage in the winter months. If your irrigation system was installed improperly, it may not function properly, leading to water contamination. If you’re looking for information on professional irrigation installation, winterization of your irrigation system, or traditional maintenance, contact us to set up a consultation.
