Planning tips for this checklist
Schedule before the first hard freeze
Irrigation winterization is mostly about timing. Once water freezes inside valves, backflow preventers, heads, or pipes, repairs get expensive quickly.
Know the drain method
Manual drains, automatic drains, and compressed-air blowouts need different steps, pressure limits, and service documentation.
Turn winter notes into spring repairs
Broken heads, leaking zones, weak valves, and controller issues found during winterization should become a spring startup repair list.
