Winterizing your swimming pool is essential to protect it from the harsh weather and ensure a trouble-free opening in the spring. Here's a step-by-step guide to winterizing your pool with efficiency, saving time, money, and effort.
Start the winterizing process before freezing temperatures arrive. The ideal time is when the water temperature consistently falls below 65°F (18°C). Early preparation allows you to take your time, ensuring you don't miss any important steps. Additionally, lower water temperatures inhibit algae growth, minimizing the need for chemical treatments.
Clean the Pool
Thoroughly clean your pool before closing it for winter. Remove all debris, including leaves, twigs, and dirt. Use a pool skimmer, vacuum, and brush to clean the walls, floor, and waterline. This ensures that your pool stays fresh, reducing the risk of staining and algae growth during winter. A clean pool will also make reopening in the spring much easier.
Balance the Water Chemistry
Balancing your pool's water chemistry is crucial to prevent corrosion, scaling, and algae growth. About a week before closing, test the water and adjust the pH, alkalinity, and calcium hardness levels.
Aim for a pH between 7.2-7.6, alkalinity between 80-120 ppm, and calcium hardness between 180-220 ppm. Add a winterizing algaecide and shock treatment to kill any remaining algae and bacteria. Allow the chemicals to circulate for a full 24 hours before proceeding to the next step.

Lower the Water Level
Lowering the pool's water level helps protect the pool structure and equipment from potential freeze damage. Lower the water level to 4-6 inches below the skimmer or tile line for in-ground pools. Lower it to 1-2 inches below the skimmer for above-ground pools.
You can use your pool pump or a submersible pump to drain the water. Remember to check local regulations, as some areas have restrictions on draining pool water.
Drain and Clean Pool Equipment
Before winterizing, drain and clean all pool equipment. This includes the pump, filter, heater, chlorinator, and any other attached components. Turn off the power supply and disconnect the equipment.
Drain all water from the pipes and equipment to prevent freezing and damage. Clean your filter thoroughly, either by backwashing (sand filters), hosing down (cartridge filters), or soaking in a filter cleaner (diatomaceous earth filters). Store any removable equipment in a dry, protected location.
Protect Your Pool Plumbing
Blow out the pool plumbing lines to remove any remaining water, which can freeze and cause damage. Use a pool air compressor or shop vac to force air through the plumbing system.
For in-ground pools, plug the skimmer and return lines with winter plugs or expansion plugs. For above-ground pools, disconnect the hoses, drain the water, and plug the openings.
Add non-toxic pool antifreeze to the lines if you live in an area with extreme temperatures. Remember, pool antifreeze is different from automotive antifreeze.
Remove and Store Pool Accessories
Remove all pool accessories, such as ladders, handrails, diving boards, and slides. Clean and dry each item before storing it indoors or in a protected area. Removing these accessories prevents damage caused by freezing temperatures and ice formation.
Don't forget to store pool toys, floats, and cleaning tools, as well. Proper storage prolongs the life of your pool accessories and ensures their readiness for use in the spring.
Install a Winter Pool Cover
A winter pool cover is essential for protecting your pool from debris, snow, and ice. Choose a cover that fits your pool size and shape, ensuring it's durable and made from high-quality materials. Use water tubes or weights to secure the cover around the pool's perimeter for in-ground pools.
Use a cable and winch system to tighten the cover for above-ground pools. Check for any rips or tears in the cover and repair them before installation. A well-fitted cover will make spring pool opening much easier.
Use an Air Pillow
An air pillow is an inflatable cushion placed under the pool cover to help distribute the weight of snow, ice, and rainwater. This prevents excess pressure on the pool walls, particularly for above-ground pools. Inflate the air pillow to about 60% capacity and position it in the center of the pool.
Secure it in place using rope or bungee cords to prevent it from shifting. An air pillow also helps reduce the accumulation of water and debris on your pool cover.
Check the Pool Cover Regularly
Throughout the winter months, regularly inspect your pool cover for damage, debris, or water accumulation. Remove any debris using a pool cover rake or brush. If water accumulates on the cover, use a cover pump or siphon to remove it.
Regular maintenance helps prevent damage to the cover and ensures that it continues to protect your pool. It also makes it easier to remove the cover when it's time to reopen your pool in the spring.
Monitor Water Chemistry
Even during the winter, it's essential to check your pool's water chemistry periodically. Aim to test the water at least once a month. Use a long pool water testing kit to collect water samples without removing the cover.
If necessary, adjust the chemicals to maintain balanced water chemistry. This will help prevent algae growth and other issues requiring extensive spring cleaning and treatment.
Winterizing your swimming pool is a crucial task for any pool owner. By following these steps, you can ensure that your pool remains in great condition throughout the winter months and is ready for a trouble-free opening in the spring.
Proper winterization not only protects your pool from potential damage but also helps save time and money on costly repairs and extensive cleaning. So, take the time now to winterize your pool and enjoy a stress-free swimming season next year.
