The Easy Way to Close or Winterize Your Pool

Above ground pools are awesome ways to have some fun during the summer, but they need to be winterized to protect them from freezing temperatures and the elements.

We will teach you how to winterize an above ground pool, the simple way.


Necessary Items for Winterizing Your Pool

There are many different items you’ll need for this process. First of all, you’ll need a quality pool cover to help protect your pool. Take a look at our reviews of the best above ground pool covers here.

The rest of the supplies needed are listed here:

Cleaning The Water

Skim the pool to remove all leaves and debris. If you have a pool vacuum, run that as well. We advise that you also take the extra time to scrub the walls of the pool to get it as clean as possible. Scrubbing the walls isn’t absolutely necessary but is recommended if you believe it’s needed. A clean pool is crucial because dirty water can lead to algae and even fungus later on.

Next, be sure to test the water to ensure it is properly balanced. A pool with water too high in alkalinity or acidity will wear away at the interior and even the cover. Use a testing kit to gauge the acidity and pH level of the water.

The pH level of the pool should be between 7.2 and 7.6 with the alkalinity level between 100 and 150. Add the proper chemicals to restore the balance before cleaning the water of all gunk and debris.

Add Winter Chemicals

Winter chemicals in a pool will shock any bacteria that may be growing inside and make it safe to store for an extended period of time. These winter kits include chlorine and algaecide chemicals. Make sure to add these according to the instructions, which are typically as simple as “pour bottle into the pool and stir it fully.”

Running the filter during this process will help propel these chemicals through the water more fully. While it is running, it’s not a bad idea to add an item known as a winter pill to the water. When this absorbs, it will make the water even more bacteria-free than it was before. This isn’t completely necessary like the other chemicals but many pool owners say it really helps.


Seal The Pool

Now it is time to remove any basket from the skimmer and to remove the drain plugs and the pump. Wash these items off and dry them fully to keep them in good shape. Everything should be stored indoors to keep it from winter damage. This is especially true of the pump and hoses. All filters should be cleaned with a hose and left open for the winter.

You will also want to remove the eyeball from your return fitting and plug it up using the Return Plug.  This is as easy step but important because it prevents water from getting inside and causing damage from freezing.

Also, make sure to use the Skimmer Cover to protect the skimmer and prevent any water from getting into the skimmer body. This also helps prevent freezing damage.


Draining The Water

Do you need to completely drain all the water to winterize above ground pool items properly? There’s a big debate on this. You should at the very least, drain some of the water and place your air pillow inside the pool on top of the remaining water. This helps keep the pool from damage caused by weather changes and other problems. Don’t drain all the water, just drain enough to get the water right below the return line.

Make sure to secure the pillow by ropes and other items to keep it centered. If it moves slightly, that’s not a major problem. However, you should try to keep it in one position as much as possible. Failure to do so could cause some minor damage.


Covering the Pool

The final step is to put the cover on the pool over the air pillow and secure it using the cover clips and the cable and winch.


The cover clips along with the cable and winch are a perfect combination to ensure your pool cover will be perfectly secure and not come loose.

Once the clips are attached around the pool cover, string the cable through the grommet holes of the cover and use the winch to tighten it up.

Make sure to check on the cover once in a while throughout the winter to make sure it’s still tight and secure.

Finishing Up

By now, you’ve more-or-less finished the process needed to winterize an above ground pool properly. Unfortunately, you’re not going to be able to enjoy your new pool as it sits out in the cold. That said, you can get it ready for Summer later and enjoy it when the weather warms up.

There’s nothing quite like the first dip in a well-protected pool that was properly winterized. We hope this article on how to winterize your above ground pool has been helpful to you. So please don’t hesitate to contact us today if you need additional help with this process.
