How To Winterize A Pool

If you are searching for “how to winterize a pool“, we’re here to provide an easy 6-step guide! 

Step 1. Test/Balance The Water

The first step to preparing your pool for the winter weather is to test the water with test strips. Then, balance the water based on your test results. This will help protect the pool from any damage that could occur at the surface.

  • Balance the alkalinity, pH, then total hardness.
  • Total alkalinity should read 80 to 150 ppm. Add a total alkalinity increaser if the levels are low.
  • pH: 7.2 to 7.6. Again, use an increaser, if needed.
  • Hardness: 175 to 275 ppm.

Step 2. Clean Pool And Filter

An essential part of the process is cleaning the pool thoroughly. 

  • Use a pool skimmer to rid the water of any floating debris.
  • Use a pool vacuum to brush the floor of the pool.
  • Empty the skimmer baskets.
  • Backwash the filter and clean the filter media with a filter cleaner.

Step 3. Shock And Circulate

A quick pool shock can clear the water of any bacteria or algae growth. A mid-winter shock is suggested for pools in warmer locations.

  • Shock the pool according to the manufacturer’s guidelines.
  • Use a quality pool shock that will not increase the water’s calcium hardness or pH levels.
  • Circulate the water for at least four hours afterwards.

Step 4. Run Pump To Prevent Algae

Take the proper precautions to prevent the growth and spread of algae in your pool.

  • Check the label directions, then add a dose of algaecide to the pool.
  • Make sure the algaecide will not cause any stains on the surface.
  • Let the pump run for 24 hours to properly disperse and circulate throughout the water.

Step 5. Winterize Pool Equipment

Pool equipment needs to be winterized and stored away for the coming winter season.

  • Turn off all equipment, according to the manufacturer’s guidelines.
  • Remove all drain plugs, pool pump, hoses and chlorinator.
  • Bring all equipment indoors.
  • Set the sand filter multiplier valve to winterize setting.
  • Drain the cartridge filter, then rinse it off and bring it indoors.
  • DE (diatomaceous earth) filters need to be drained. 

Step 6. Plug And Cover Pool

Make sure the pool cover is large enough and durable to withstand any harsh weather.

  • Remove eyeball fitting on the return line and plug it using a rubber plug/wing nut.
  • Drain the pool 4-6 inches below the skimmer. Add a skimmer cover after.
  • Blow up air pillow and place it in the middle of the pool.
  • Put on and secure the pool cover.
  • Remove ladder or any other deck equipment.
  • Store all chemicals/equipment indoors.
