In Park City, freezing weather can put irrigation pipes, valves, and backflow components at risk. Winter preparation is more than switching off the controller: water left in vulnerable parts of the system may freeze and cause damage. Before temperatures drop, arrange a seasonal review with an irrigation professional. Together, you can confirm how water should be shut off, which components need draining or protection, and how to set the controller for the dormant season.
Review the System’s Layout
Ask your irrigation professional to identify the main shutoff, backflow assembly, valves, low points, and any above-ground piping. Knowing where these components are—and how they are connected—helps determine the right winterizing steps. System design, soil conditions, and exposure vary, so avoid assuming that a neighbor’s process is suitable for your property.
Walk the property together and note areas where water may collect, such as sloped sections, valve boxes, or lines near a foundation. Ask whether any components need repairs before winter. A small leak or a damaged enclosure can leave equipment more exposed to freezing conditions and may be easier to address before the system is shut down.
Shut Off and Clear Water Safely
Discuss where and when to shut off the irrigation supply. Your professional can explain whether the system should be drained, blown out with compressed air, or winterized using another method suited to its layout. Compressed air can damage pipes or sprinkler components if pressure or procedure is inappropriate, so leave this work to someone familiar with the system.
Ask how the backflow preventer and other exposed equipment will be protected after the water is off. Some assemblies have specific draining and insulation requirements. Confirm that any covers or insulation are appropriate for the equipment and local conditions, and that they do not trap moisture where it could cause problems.
Set Controls for the Dormant Season
Once the system is winterized, ask whether the controller should be switched off, set to a rain or off mode, or left with power for a specific feature. The right setting depends on the controller and system. Review how to restore the normal schedule in spring, and keep a note of any settings that should not be changed.
If the controller has a backup battery or seasonal adjustment, ask whether either needs attention. Check that the displayed program matches the winter plan and that automatic watering will not restart unexpectedly. A clear handoff from the professional makes spring startup easier and reduces guesswork.
Plan a Spring Recheck
Before the visit ends, ask what signs of winter damage to watch for and when to schedule spring startup. A professional can inspect the system before turning water back on, then test zones, heads, valves, and controls in sequence. Opening the supply gradually and checking for leaks can help reveal issues before they affect landscaping or nearby structures.
Keep the professional’s notes with your home maintenance records, including shutoff locations, work completed, and recommended spring steps. If you notice a leak, a damaged cover, or unexpected water during winter, contact a qualified irrigation professional rather than restarting the system yourself.
A careful winter review protects irrigation equipment and gives you a clear plan for spring. Discuss the system’s layout, water removal method, exposed components, and controller settings before freezing weather arrives.
