Irrigation Winterization–Protect Your System and Avoid Spring Headaches
As the days shorten and temperatures dip, it’s time to think about one last thing for your landscape: winterizing your irrigation system. Preparing your system for winter is an important step in protecting your investment and making sure your landscape is in great shape when spring rolls around.
Why Winterize?
Efficiency is the single most important factor when watering your lawn or garden. Older sprinkler systems can leak, underperform, or freeze up when temperatures drop, making professional winterization especially important. Even modern systems need attention as they age: seals, solenoids, and valves wear; fittings loosen, and controllers fall out of sync. Left unprotected, your irrigation system faces two big winter risks: freeze damage to pipes and valves, and water sitting in lines that can lead to corrosion. Having a pro shut down your system means each part gets inspected and purged of water, avoiding potentially costly damage. Done properly, winterization prevents burst lines, damaged valves, and the slow leaks that can quietly drive up water bills.
Regular Maintenance = Fewer Surprises
During irrigation season—typically from Memorial Day through mid-September in our area, weather permitting—your system should be checked regularly. We recommend monthly inspections so controllers and run times can be adjusted for changing conditions, and technicians can spot wear before it becomes a failure. During these visits, a tech can:
- Verify controller settings and seasonal schedules
- Inspect heads, nozzles, and filters for clogs
- Test valves and look for leaks or broken pipes
- Adjust water distribution to maintain even coverage and conserve water
These checks keep your landscape in good health, as well as building a maintenance history that makes budgeting and planning for future upgrades easier.
DIY vs. Professional Winterization
There are a couple of things homeowners can do to prepare: turn off the water to the irrigation main and remove the battery from the timer for long-term storage. But much of winterization–like blowing out lines and protecting backflow devices–requires the right tools and experience. for peace of mind, and to protect warranties and insurance coverage, we recommend having a certified irrigation contractor handle those elements of winterization.
