End-of-Season Shutdown: A Simple Checklist

Quick checklist to button up your misting system for fall and winter — and what you can leave to us if you'd rather not.

Even before the first hard freeze, it's worth shutting your misting system down for the off-season. A proper shutdown saves wear-and-tear on the pump, extends nozzle life, and gets the system ready for a clean spring restart. Here's a quick checklist.

Late-season shutdown checklist

  1. Run the system one last time at full pressure to flush out any mineral deposits in the nozzles before they dry in place. (Here's why that matters: how to keep nozzles from clogging.)
  2. Close the dedicated water supply valve feeding the misting line.
  3. Briefly run the system with supply closed to bleed any pressure from the line.
  4. Open the drain valve at the lowest point in the system to gravity-drain the lines.
  5. Wipe down the pump enclosure and check pump oil. If oil is dark or there's any moisture in the bottle, schedule service.
  6. Remove or cap exposed nozzles only if you live somewhere that birds, bugs, or debris might fill them over winter.

What to leave to a pro

A compressed-air line blow-out and a pump oil change are best done by a technician with the right adapters and oil spec. Both are inexpensive, quick, and they push the freeze-damage risk to essentially zero.

Don't forget winterization

Off-season shutdown ≠ winterization. Shutdown is a comfort/seasonal move. Winterization specifically protects the system from a hard freeze. Read our full winterization guide for the details, or have us handle it — our maintenance team can knock out both in one visit.
