How To Winterize Your Above Ground Pool In 9 Easy Steps

Have a pool which you want to close temporarily? Is it time to winterize an above ground pool? Winterizing your swimming pool saves you a lot of hassle when summer arrives and it is time to swim again. It is important to winterize your swimming pool in order to protect it from harm due to freezing water.

I know a lot of people who don’t do it and end up with a pool that isn’t fit for swimming when winter is over. So, it is always preferred to be safe rather than sorry. There’s no need for you to feel hesitant about winterizing an above ground pool because it is very easy. In this article, you will be able to learn how to winterize an above ground pool in 9 easy steps!

What you need?

  • A pool cover if you have a round or an oval pool
  • Cover clips
  • Water bags, if your pool also has a walk around deck.
  • An air pillow which is a must for all above ground pools.
  • Return plugs; either plastic or rubber.
  • Winter chemical kit.
  • Winter skimmer cover.
  • Winter pill which helps in keeping the pool clear throughout winter. This is not really required for winterizing but it is highly recommended.

With all these things ready, let’s start with the process to winterize an above ground pool.

1. Checking the water chemistry:

You need to ensure that the total alkalinity, calcium hardness, and pH are all balanced in the pool’s water. This helps in protecting the surface of your pool from etching and staining. That is why before you decide to close your pool you need to test the water.

You can either go to a local pool store or you can buy test strips and perform the test on your own. The ideal pH of the water should range from 7.4 to 7.6 while the ideal alkalinity levels should range from 100ppm to 150ppm. When it comes to closing the pool, being on the higher spectrum of these ranges is much better.

2. Add winter chemicals:

Before you add the winter chemicals, make sure that your above ground pool is absolutely clean. This means that before you add the chemicals, vacuum the pool, skim the surface, and brush down the walls. In such a case where you have a chemical kit, just follow the instructions given on the kit.
 
However, in the event where you don’t have a kit, you should use chlorine shock along with winter algaecide (read more about it here). The amount of winter algaecide that you should add to your pool depends on the size of your pool and can be found on the back of the algaecide bottle.
 
Instead of going for the calcium hypochlorite shock for closing your pool and getting it ready for winter, you should use the 15-minute fast dissolving shock since calcium takes about 8 hours before you can cover your pool. You can also use a WinterPill which ensures that you get a clear pool when you re-open it. Just puncture a hole in the pill and drop it in the water.

Take Note!

There are a few chemical kits that don’t need you to filter the pool before you add them. Therefore, it is first important to read the directions written on the kit you have. If you have a kit that doesn’t need you to run the filter and the pump, then you can skip the next step and directly cover your pool.

3. Plug the pool:

From your return line, remove the eyeball fitting and plug it with the help of a wing nut. Meanwhile, on the skimmer, remove the basket and store it for the winters.

Here, you have the option of using winter skimmer covers which are basically plates that are meant to cover the skimmer. This saves you from draining the pool underneath the skimmer. If you don’t have a winter skimmer cover, you can use a solid cover. Also, make sure that you don’t plug the skimmer’s bottom.

Take Note!

If you are using a solid cover, then draining the water below the return lines can put additional pressure on the cover. That is why you will have to keep draining water off the cover by using a siphon or a winter cover pump in order to protect it.
 
If water fills the empty skimmer in the winter and freezes it, then it can cause the skimmer to crack. Also remember that if an obscene amount of water or snow fills the skimmer, the weight of it all is very damaging for your skimmer.

4. Winterize the filter:

The right method of winterizing a filter depends on the kind of filter that you have. So, first you need to make sure about the kind of filter that you have. If you’re not sure, check it here.
 
If your filter is a sand one, then you need to set the multiport valve to winterize. Then, remove the plug at the bottom, allowing the filter to drain out completely. If your valve comes with a sight glass and a bleeder valve, remove them and store them in a pump basket.
 
When it comes to a D.E. filter, first you’ll need to drain it, proceed to rinsing the grids using a hose to get rid of the excess D.E., and then leave the valves open.
 
For a cartridge filter, drain it and then rinse the cartridge using a hose. The cartridge is to be stored indoors throughout winter and the valves are to be left open.

5. Winterize the pump:

Remove all of the drain plugs completely. If you have a chlorinator, remove it along with the pump and the hoses. Remember to store all of the drain plugs, even those from the filter inside the pump basket so that you don’t lose them. It is highly recommended to keep the hoses, the chlorinator, and the pump indoors because this prolongs their life.
 
Once you have drained the pump, you can switch it on just for a brief moment so that all of the water comes out from the veins of the impeller. However, remember that you should not switch on the pump for more than two seconds since there is a chance that you can burn the seal.
 
If you happen to have a chemical feeder, you need to allow the chemicals to run out of the feeder. Leaving chemicals in the feeder throughout winter can cause damage to it.

6. Store the equipment:

Once you have disconnected the pump system and the filter, you need to store all of the equipment indoors. This includes the chlorinator, the heater, the pump, the filter, and any equipment that you possess.

If you have a sand filter, storing it inside can be a problem because the weight of the sand makes it difficult to move the piece indoors. If you opt for leaving the sand filter outside, then make sure that all of the drain plugs have been removed.

Doing this ensures that even if condensation or water builds up within the tank and freezes, the filter tank won’t crack. Meanwhile, the other filters like the cartridge and the D.E. filters are light enough to store easily indoors. It is also the right time to take out the pool ladder and other equipment that you might have inside the pool.

7. Addition of the air pillow:

Blow the air pillow and put it in the center of the pool. In order to ensure that the air pillow stays in the middle, you can make use of a thin rope and secure it to either side of the pool.

Alternatively, you can go for a pool pillow pal. Honestly, it doesn’t matter whether the pillow remains at the center or not throughout winter.

It is common for people who own an above ground pool to only use the air pillow in order to prevent the sides from bearing the excess pressure exerted on them when the water freezes and expands. The bottom line is that the air pillow is not needed which means that you can skip this step, but it is highly recommended.

8. Put on the cover:

put the pool cover on properly

Place the pool cover on top of the pool, including the air pillow. Secure the cover with the help of water bags, cable, winch, or with a combination of a cable and winter cover clips.

If your pool also has a walk around deck, then the most recommended equipment for doing this step is a combination of cable, winch and winter cover clips.

9. Take precautions:

Precaution

We are taught in school that water expands when frozen and you need to keep that in mind. Due to this phenomenon the pool plumbing, the filter system, and the pool in general experiences great damage.

If you have decided to winterize an above ground pool then you need to make sure that you take the necessary precautions in order to protect your pool from experiencing damage due to frozen (expanded) water.

Conclusion:

Remember, winterizing an above ground pool is beneficial in a number of ways; you get a clean pool for summers and your equipment stays safe. Was this tutorial helpful for you?
