Close your pool once the local temperatures dips below 60°F. Algae does not survive in cool water, and closing the pool once the temperature is low reduces the likelihood of finding algae growth in the spring.
If your local temperatures during your pool’s off-season are frequently above 60°F, uncover the pool to test and balance the water repeatedly to prevent algae growth.
Treat the pool with winter pool closing test kit or balance the water yourself to prevent corrosion or heavy calcium buildup during closure.
Skim the water to remove leaves, insects and debris before brushing and vacuuming your pool. Any refuse left in the water will decay once the pool is covered.
Remove fine particles and other contaminates before you close your pool by running the filter for 24 to 48 hours.
After running the filter for 24 to 48 hours, remove the skimmer baskets, cleaners, ladders, hoses, filters, solar blankets and other equipment and pool accessories.
The pool’s water level should be 6” (150mm) below the skimmer level. Drain at the prescribed rate of 1” (25mm) per hour.
Remove the water from all filtering, heating, pumping and sanitizing equipment to prevent damage caused by freezing.
Protect pool attachments against freezing by lubricating O-rings, valves and plugs and blowing out all lines.
Use expansion plugs to keep any water from getting back into your pipes. Extra water can freeze and expand, bursting the lines.
A tight-fitting winter pool cover protects your pool from the weather and any debris that may blow into the water.
Check the pool after severe weather. Winter storms or blizzards can raise the water level in your pool. If that water freezes, it can crack the tiles or even the foundation of your pool.
