Pool closing checklist

It's that time of year when pool owners are mourning the loss of summer. Swimming season is over and now the pool must go into hibernation. So long, refreshing swims on hot summer days! It's time to winterize your pool.
Here's a checklist to help you properly close your pool.

  • All the experts recommend closing the pool as late as possible, around mid-October. So it's not worth rushing to do it.
  • Give it a good cleaning: vacuum the pool and do a complete backwash to remove all the dirt and debris.
  • Shock the pool (alkalinity between 100 and 120 ppm and pH between 7.2 and 7.4). The massive dose of chlorine will eliminate microorganisms that could otherwise multiply.
  • Clean all the accessories. Everything must be clean, from the filter to the solar cover to the skim net.
  • Use the "drain" or "waste" feature on your filter to lower the water level of the pool.
  • Drain your pool until the water level is 15 to 18 inches below the skimmer.
  • Shut off the pump and store it. Turn off all power and then disconnect the hoses and clean them. Store the pump indoors in a dry place.
  • Clean the filter and store it.  You'll need to follow your pool's maintenance manual—there are many types of filters, and each one must be cleaned a specific way. When the filter is clean and completely drained, set the valve to "Winterize" position.
  • Fill the main drain line with pool antifreeze. Some experts also inserting foam rope into it.
  • Remove the door, basket and cover plate from the skimmer. The insert a foam block into the skimmer.
  • Screw winterizing plugs onto the return lines. Before you do this, you'll need to unscrew the ring and remove the eyeball seat.
  • Put the winter cover on the pool. Here's a good trick: put an inflated beach ball under the cover to make it easier to remove snow and water.
  • Shut off the heater.
  • During winter, do not break up the ice on top of the pool—it could damage your cover.

And voilà! It's a lot of little things to do, but they are essential for keeping your pool in good condition. You can find more useful tips on the Association des commerçants de piscines du Québec website Good luck!
