An irrigation system can keep your lawn lush and green during the drier months. Like any plumbing infrastructure, though, it requires regular maintenance to function properly. One of the most common issues that plagues irrigation systems is backflow. Here’s what you should know so you can recognize when there’s a problem and call in the professionals for help. 

FAQ About Irrigation Backflow 

What is backflow?

When the pressure in an irrigation system drops, the water that's supposed to flow out into the lawn can reverse and flow back into the plumbing instead. This water is called backflow, and it can cause serious problems for the whole community. 

Why is backflow a problem?

Backflow is an issue because the water is likely contaminated with pesticides and fertilizers. While great for your lawn, these substances should be nowhere near the water that flows into your home. If the backflow gets into the public water supply, though, it will eventually come out through the tap and could make people ill. 

What is backflow testing?

Backflow testing is a simple process that reveals whether a property’s plumbing system has been contaminated. Generally speaking, it’s wise to schedule annual testing, even if you have a backflow preventer. Since these devices are not foolproof, testing can provide some peace of mind—or let you know there's a problem that needs addressing. 

Should I get a backflow preventer?

If you want to be a responsible homeowner, you should install a backflow preventer when putting in or upgrading your irrigation system. This device will stop the flow of water from reversing, even if there is a drop in pressure. And depending on your municipality’s regulations, you may actually be required by law to install one.
