How To Winterize A Pool

Winter is coming…for your pool! Follow these tips to make sure that your pool is kept in tip-top condition all winter long so that you can better enjoy it in the warmer months.

If you’re wondering how to winterize a pool, you’ve come to the right place! Simply follow these 7 steps.

While you may not want to think about summer coming to an end, as a pool owner you need to! Winterizing your pool is an important part of maintaining it — your pool could become damaged if you don’t properly close up shop. We’ve already shared our favorite tips for preparing your hot tub for winter, and now it’s time to move on to your swimming pool.

You need to begin thinking about how to winterize a pool as soon as the temperatures start to drop to 65 degrees F or lower. Winterizing your pool should take about one week in total. 

Step 1: Remove Any Pool Accessories

Most pools will feature some sort of accessories. This could include ladders, heaters, toys, and the like. When you remove them, make sure to rinse them off with water or clean them if necessary. You won’t want to store these items if they’re dirty as they could become damaged. Allow them to dry before stowing them in your shed or pool house.

Step 2: Clean Your Pool

Before closing up your outdoor oasis, it needs to be clean — just like the accessories. We’ve got plenty of DIY pool maintenance tips up on the blog if you don’t want to hire someone else to do it. A few things to keep in mind:

  • Clean out the filters
  • Remove any debris such as leaves and twigs
  • Clean the sides and bottom with a pool vacuum

The cleaner your pool is when you winterize it, the easier it will be to open it back up for the season!

Step 3: Adjust and Balance The Chemistry

Remember that your pool water contains delicate water chemistry that must be balanced. A week before you winterize it, make sure that the chemicals are balanced as follows: 

  • Chlorine: 2.0-4.0 ppm
  • pH: 7.4-7.6 ppm
  • Total alkalinity: 80-120 ppm
  • Calcium hardness: 200-400 ppm 

As a rule, try to achieve the higher side of these numbers because they will deteriorate over the winter as it becomes colder. 

Step 4: Lower The Water Level

Since you won’t be using your pool for months at a time, you don’t need to worry about keeping the water levels high. Lower it to about a foot below the skimmer for the best results. The exact level will differ depending on what type of pool cover you’re using: 

  • Mesh cover: 12 inches below the skimmer 
  • Solid cover: 6 inches below the skimmer

Step 5: Drain The Equipment

If you skip this step, you could severely damage pool equipment such as heaters, filters, and pumps. If water remains lodged inside them and freezes, it will expand and crack any fragile accessories and equipment. 

To be extra safe, you may also consider putting pool antifreeze in the blowers to guarantee the pipes won’t burst. If you can, remove the filters and pump and clean them — store them inside for the winter if possible.

Step 6: Add Bacteria-Killing Chemicals

You can use pool shock and algaecide to get rid of any bacteria and algae before you cover your pool for the winter. You can find these kinds of chemicals at your local pool supply store. Follow the instructions as directed and make sure to evenly distribute the chemicals. You don’t want to shock one area and forget the rest!

Step 7: Cover Your Pool

The last step to learning how to winterize a pool is to cover it up and say bye-bye until next season! There are two types of pool covers that you can use in the winter: safety covers and winter covers. We typically recommend that you opt for a safety cover as they are the most secure. They will protect your pool from the elements, debris, and people or animals who may walk on it by mistake. Using the pool cover of your choosing, cover it and secure it tightly. 

A Note On Above-Ground Pools

The instructions above are for in-ground pools, but you can follow the same steps for above-ground pools as well. One extra step that you’ll want to do is to place an air pillow in the center of the pool before placing a cover on it to keep any snow from damaging it.

Follow these steps and your pool will be ready to take on the winter months!
