How to Winterize Your Irrigation System
Getting your yard ready for harsh winter weather is a great way to ensure a successful spring. The more you do now in the preparation stage, the less you’ll have to worry about when your lawn wakes up from dormancy in spring. Winter weather can inflict serious damage onto your grass and irrigation systems if they aren’t properly prepared. Winterizing your irrigation system to help prepare it for freezing temperatures is a crucial step in winter lawn maintenance to prevent costly repairs down the road.
If you’re unsure how to winterize your lawn’s irrigation system, read on for a step-by-step guide to help you get started.
Why Winterizing Irrigation Systems Is Important
Winterizing your irrigation system is essential to protect it from freezing temperatures that can cause pipes to crack, valves to break, and lead to costly repairs come spring. This preparation not only safeguards your system but also supports the health of your grass by avoiding winter root rot and disease.
Another way to prepare your lawn for the lack of irrigation in the winter is by supporting the soil underneath. Applying a nutrient-rich soil amendment, such as Jonathan Green Love Your Soil Hard Soil Supplement before winter can enhance soil structure and improve water retention, which is especially beneficial in areas without consistent winter irrigation. Healthy soil retains nutrients, reduces erosion, and provides a stable environment for roots, allowing your grass to bounce back stronger in the spring.
How to Winterize Your Irrigation System
Turn Off Your Water Supply
The important first step in winterizing your irrigation system is to shut off the main water valve to prevent any new water from entering it. Double-check for leaks to ensure no water remains that could freeze, expand and break the valves.
Drain Pipes
Clear out all water from the system by either manually draining it or using an automatic drain if your system is equipped with one.
Insulate Above-Ground Components
Insulating exposed pipes and any above-ground components, such as backflow preventers and valves with foam or specialized covers prevents freezing damage. If possible, remove any sensitive parts and store them indoors until spring.
Prepare Irrigation Controller
Switch your controller to “off” or “rain mode” to prevent accidental activation during the winter. For battery-operated controllers, remove the batteries to avoid corrosion and replace them with fresh batteries in the spring.
Clean Sprinkler Heads
Before winter, remove dirt, grass clippings, and any debris around your sprinkler heads. This ensures that they won’t be clogged over the winter and be ready to use as soon as your grass exits the dormancy period in the spring.
Inspect each head for any cracks or clogs, and make repairs as needed so your system is ready to roll when it’s time to start watering again.
