Pool Winterization Process


Winter can be a hard time for outdoor recreation.  You can’t swim in frozen water, but did you know that it can also damage your pool’s internal workings if you’re not careful?

Here are some easy steps to take to winterize your pool and prepare it for the cold months ahead.


Winterize Pool



Protect your pool first by checking its pH balance – a good pH balance at the beginning of the winterizing process is recommended in order to prevent staining in your pool during the winter.  If your alkalinity or calcium content is too high, you may be in for some nasty marks later on.

You can also flush your pool’s systems to make sure that everything is clean.  At this point, do not add any more chlorine or other pool cleaning chemicals to your pool water.



The first thing you want to do after making certain that your water’s mineral and acidity content are at a good level is to drop the water level down below the mouth of your skimmers.  If this is not an option, there are covers for your skimmers available.

Remember that water expands when it freezes, and any water in your pool’s internal workings during the winter has the potential to freeze and damage your pool.

Make sure to drain and dry out any of the following that your pool has:

  • skimmers
  • plumbing lines or hoses/hose inputs
  • filters and filter systems
  • pressure or temperature gauges



Covering your pool will help keep out leaf litter, snow, and other moisture that may undo your winterizing.  Without a cover, all of your winterizing can be undone by moisture and unwanted items getting into your pool’s systems and clogging them up.

Also be sure not to tighten your cover too tightly to prevent it from breaking under the weight of snow.



To prevent accidents, be sure not only to cover, but make your pool inaccessible to anyone who might not see it under the snow.  Fence it in or put something light on top so that you know where it is and can’t fall in.

If you have an above-ground pool, remove any ladders to prevent family from trying to ice skate, as you can still fall through and get hypothermia if the ice inside your above-ground pool is thin.


Prevent winter accidents and damage this year by winterizing your pool as best you can!
