Pool Closing Checklist
For residential pool owners preparing a seasonal shutdown. Adapt the work to your pool, cover, equipment and local freeze risk; a mild-climate pool may need a different off-season plan.
Before freezing weather / seasonal shutdown
Before you start
- Gather pool, equipment and cover manuals, current test supplies, cleaning tools and label-specified protective equipment.
- Keep children and pets away. Do not empty the pool or improvise compressed-air winterization. Use qualified help for unfamiliar plumbing, electrical or pressure-system work.

Do not drain the pool completely. Follow the pool and cover manufacturers’ instructions on whether and how far to adjust the water level.
-
If plumbing or equipment must be winterized for a seasonal shutdown.

Clean and dry equipment; follow battery storage temperatures and charging guidance.
Secure and record
