When to Close Your Pool for Winter


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.
 
 

 

BALANCE YOUR WATER FOUR TO SEVEN DAYS BEFORE YOU CLOSE THE POOL

  • pH: 7.2–7.6
  • Total Alkalinity: 80–120 parts per million (PPM) [80–120 Ml/L]
  • Calcium Hardness: 180–220 parts per million (PPM)
  • Chlorine: 1–3 parts per million (PPM)

Step-By-Step Pool Closing Instructions

STEP 1: BALANCE THE WATER

Treat the pool with winter pool closing test kit or balance the water yourself to prevent corrosion or heavy calcium buildup during closure.

STEP 2: ADD SHOCK TREATMENT & ALGAECIDE

Disinfect your pool with a double dose of shock and then a double dose of algaecide. This prevent discoloration and foul smells over the winter.

STEP 3: CLEAN THE POOL

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.

STEP 4: RUN THE FILTER

Remove fine particles and other contaminates before you close your pool by running the filter for 24 to 48 hours.

STEP 5: CLEAR THE ACCESSORIES

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.

STEP 6: LOWER THE WATER LEVEL

The pool’s water level should be 6” (150mm) below the skimmer level. Drain at the prescribed rate of 1” (25mm) per hour.

STEP 7: MAINTAIN THE EQUIPMENT

Remove the water from all filtering, heating, pumping and sanitizing equipment to prevent damage caused by freezing.

STEP 8: DRAIN THE LINES

Protect pool attachments against freezing by lubricating O-rings, valves and plugs and blowing out all lines.

STEP 9: PLUG THE LINES

Use expansion plugs to keep any water from getting back into your pipes. Extra water can freeze and expand, bursting the lines.

STEP 10: USE A COVER

A tight-fitting winter pool cover protects your pool from the weather and any debris that may blow into the water.

 

Tip

PRO TIP:


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.
