Leaves are changing, temperatures are cooling, and, for certain climates, that means it’s the sad time of year to close your swimming pool.

Closing your pool is a simple process that either you or your pool professional can do. If you plan on closing your own pool, make sure you follow these 10 pool closing steps to avoid expensive repairs in the spring.

How to Close Your Pool For Winter

1. Make sure to begin one week before you would like your pool completely closed.

2. Unbalanced pool chemistry can damage or destroy your pool equipment. Balance your pool water chemistry to these ranges:

  • pH: 7.2 – 7.4
  • Alkalinity: 60 – 120 ppm
  • Cyanuric Acid: 20 – 40 ppm
  • Calcium Hardness: 200 – 400 ppm

3. Vacuum and brush your pool to help prevent algae growth ahead of time.

4. Backwash and clean your filter.

5. Use a chlorine shock to kill any visible algae.

6. Manage your water level accordingly to your local climate*.

  • If your climate experiences freezing temperatures in the winter – adjust your water level four to six inches below the skimmer and tile.
  • If your area doesn’t have freezing temperatures in the winter – fill your pool water to a regular level and periodically check for evaporation. Also, remember to balance your pool chemistry at least once a month.

7. If you live in a region with freezing temperatures*, you’ll need to:

  • Drain pool lines and add antifreeze.
  • Drain your filter, blow out the plumbing lines and remove all freeze plugs.
  • Turn off all power breakers.
  • Drain your Clear Comfort injection Manifold or bypass and unplug your blue Air Tubing from the Venturi.
  • Turn off all unused equipment and cover to protect from snow and ice damage.
  • If needed, remove unused hoses. Store hoses and Air Flow Meters in a safe, secure place.

Tip: Check your pool equipment manufacturer’s recommendations for complete winterizing instructions. If you have a Clear Comfort pool, please refer to our complete pool closing guide.

8. Apply an algaecide to your pool.

9. Put a safety cover or a leaf cover your pool (use an air pillow underneath the cover if required).

10. Store all ladders, pool toys, robotic cleaners, etc. in a safe place. Also, separate and store your chemicals in a well-ventilated, climate-controlled space.
