How to Winterize your Pool
Closing your Pool for the Winter
Taking good care of your swimming pool in the summer is important – but it’s just as important to take care during the winter months too. Maintaining a swimming pool requires some extra attention once the temperature drops, to keep the pool as clean as possible, and ensure it maintains structural integrity. Take care of your pool at the end of the summer, and help make sure it’s in great shape to use the following year.
One of the most important steps in winterizing the pool is removing water from the pump, plumbing, filter, and other structures which are sensitive to structural damage. This is crucial if you live in a location where freezing temperatures are a possibility – even if the possibility is low. Water expands when it freezes, so any water remaining in these areas may expand enough to cause damage.
Step One: Cleaning
The swimming pool should be thoroughly cleaned before any other winterizing steps are undertaken. It’s crucial to ensure that all debris is removed at this point. Ideally the pool won’t be disturbed at all over winter, so to help the winterizing chemicals do their job, the pool should be as clean as you can make it. Even a small amount of debris could allow algae to grow.
Remove all pool toys and accessories at this stage, too. Store these items in a safe place where they’ll be protected from the elements over the winter.
Step Two: Add Winterizing Chemicals
Next, use a chemical winterizing kit. These kits, when applied to your pool’s water, will help prevent it clouding up over the winter. Most kits differ slightly depending on themanufacturer, so be sure to follow your particular kit’s instructions closely
Step Three: Drain the Plumbing
Next, water should be drained or blown out of the plumbing lines, pump, heating system, and filter. Blowing is more effective than simple drainage, as blowing will ensure the removal of smaller water droplets that might remain after draining.
Step Four: Cover the Pool
Double-check to make sure every task is completed, and then cover the pool. To ensure the swimming pool stays clean and free from algal growth over the winter, use a solid cover, as this will block both sunlight and debris. A mesh cover can be used, and this will prevent leaves and other large debris from getting into the water. However, the water won’t be protected from dirt and other debris, or from sunlight. Essentially, using a solid cover over winter means less work is needed to make the pool usable in the summer.
Consider using an air pillow. These items sit on top of the surface of the water, beneath the pool cover. Adding an air pillow turns the cover surface into a dome-shaped structure, so that excess debris, water, and snow will not collect on the cover.
With these steps taken, your swimming pool will be protected from winter damage, and the task of opening the pool up will be much easier when the weather grows warmer.
