How to Prepare Your Swimming Pool for Winter

How to Prepare Your Swimming Pool for Winter
  • Opening Intro -

    Labor Day marks the unofficial end of summer.

    For many homeowners, it also is one of the last times of the year that they will be using their swimming pools as cooler weather sets in and thoughts turn to school and fall activities.


Of course, if you live in Hawaii or south Florida, you may use your pool year ’round. For everyone else, preparing a swimming pool for winter involves several important steps.

1. Treat your pool with chemicals.

You won’t be draining your pool completely of water, but you will be lowering the water level. The first step to take is to clean your pool and ensure that it has the proper chemical balance for winter. That means a pH concentration of 7.2 to 7.6 with a total ppm of 80 to 125 for most pools. Calcium should measure 175 to 225 ppm, a chlorine stabilizer should be at least 30 ppm and free chlorine should come in at 1.0 to 4.0 ppm according to Lowes.

2. Remove and store equipment.

Ladders, railings, toys, volleyball nets and all other recreational goodies need to be take out of your swimming pool. Once each has dried, put these items in storage.

3. Place winterizing chemicals in your pool.

You will want the pool water to stay clean while it is covered up and out of use until the next swimming season. Add in a winterizing chemicalto keep your water clear. Follow the manufacturer’s instructions for a precise job.

4. Check filters and skimmers.

Debris, dirt and other decontaminants can accumulate inside of your pool’s filters and skimmers. Remove debris and other obstructions.

5. Drain the pool to the proper level.

You are now ready to remove some of the pool’s water. Depending on the type of swimming pool you have, that level will range from 1-inch to as much as two-feet below the skimmer opening. Follow your pool’s instruction’s guide as those levels vary depending on the type of pool and the cover used.

6. Remove and install.

At this point in the swimming pool winterization process, you are ready to remove the directional fittings and install the freeze plugs. Store these fittings with your pool supplies.

7. Install your pool cover.

Your final step is to install a pool cover. Here, you must follow the manufacturer’s instructions. In addition, you may need assistance to complete this task. Your work is done once the pool cover is securely in place.

Winterization Considerations

If you live where extreme cold sets in during the winter, you may need to add in a non-toxic antifreeze. Different from automotive antifreeze, this chemical generally comes in 1-gallon container or may come concentrated in a 1-quart container. Look for protection to as low as minus 40 degrees Fahrenheit, wherever possible.
