Winterizing your swimming pool in areas where temperatures drop below freezing is crucial to prevent damage during the winter. Whether you have an above-ground, in-ground, or saltwater pool, winterization keeps your pool equipment in good shape and ensures clean, safe water. It also protects your pool from freezing and makes spring opening easier.
This blog is a step-by-step guide to winterizing pools, including above-ground and saltwater pools. It also explains how to avoid common mistakes while closing a pool.
Let’s find out more!
What is pool winterization?
Pool winterization prepares a swimming pool for cold weather to prevent damage from freezing temperatures. It involves cleaning the pool, lowering the water level, and adding chemicals to maintain water quality. Proper winterization protects the pool structure and equipment and makes its reopening easier.
Why is Winterizing a Pool Necessary?
Pool winterization is necessary because:
- Protects the pool structure and equipment from freezing temperatures.
- Minimizes algae growth and debris buildup during winter.
- Helps extend the life of pool components like pumps and filters.
- Makes reopening the pool in spring quicker and easier.
- Keeps water chemistry stable, reducing the need for significant cleanup later.
Materials/Tools Required While Winterizing a Pool
You will need the following materials or tools while winterizing a pool.
| Equipment / Tools | Materials |
| Conical hose connector | Pool winterization kit |
| A blower or shop vac | Return line plugs |
| Standard pool cleaning tools | Skimmer plug |
| Submersible pump or siphon | Pool antifreeze (optional) |
| Air pillow (optional) |
What are the different steps to winterize your pool?
Here is the stepwise pool winterization process to help you prepare for winter pool care:
Remove Pool Accessories
Remove ladders, floats, and toys from the pool and clean and dry them thoroughly. Rinse them with water to remove dirt and chemicals. Store accessories in a dry, shaded area to prevent UV damage and prepare them for spring.
Deep Clean the Pool
Brush the walls and floor to remove algae and stains. Use a vacuum designed for your pool type to collect debris thoroughly. Check and clean the skimmer basket and pump basket to enhance circulation. This will prevent pool algae buildup and make reopening easier.
Test and Adjust Your Water Chemistry
A balanced chemical level for your pool water is necessary before preparing for pool winterization. Test and adjust your pool’s water chemical balance. Here is what a balanced pool water chemistry looks like:
- Alkalinity: 80–120 parts per million (ppm)
- Calcium hardness: 200–400 ppm
- Chlorine: 2–4 ppm
- pH: 7.2–7.6
Lower the Water Level
Use a submersible pump to lower the water to about 4-6 inches below the skimmer. This prevents freeze damage to skimmer fittings and pipes. Drain water away from the pool area to avoid flooding. Lowering the level also prevents overflow from melting snow.
Drain, Disconnect, and Store
Drain all hoses, pumps, and filters completely to prevent ice formation. Disconnect all equipment, including heaters and salt systems, and store them indoors. Wrap and insulate any exposed pipes to avoid freezing. After that, properly store all the equipment and materials to extend the life of your pool gear and ensure optimal performance.
Add Shock and Algaecide
Add pool shock in the evening to prevent sunlight from breaking it down. Use a granular shock for effective algae control and follow the package instructions. After shock treatment, add algaecide to keep it clean and fit for reopening in the swimming season.
Cover the Pool
A cover protects the pool from harsh weather and simplifies spring opening. Use a sturdy, winter-grade pool cover that fits securely over the pool. Ensure it’s tightly secured with water bags or stakes to withstand winter winds. Check the cover regularly for debris buildup and remove it promptly.
How to Winterize Above-Ground Pools?
Winterizing an above-ground pool is similar to an in-ground pool; however, it is slightly different because of the above-ground pool’s structure.
Remove the Ladder: Take out any attached ladders and store them indoors.
Add a Winterizing Chemical Kit: Use a winterizing chemical kit specifically designed for above-ground pools.
Drain the Pump and Filter: Ensure all water is drained from the pump, filter, and hoses.
Use a Pool Pillow: Place a pool pillow under the cover in the pool’s center. This helps keep the cover from collapsing under snow and ice weight.
Secure the Cover with Cables: Use a cable and winch system to secure the cover tightly. This prevents it from blowing off or being displaced by winter storms.
How to Winterize a Saltwater Pool?
Though saltwater pools require less maintenance and cleaning than traditional chlorinated pools, they still need proper winterization. Here is how to do it:
Adjust Salt Levels
Check the salt levels in your saltwater pool to prevent it from rusting and make opening the pool easier next spring. The salt levels should be between 2700 and 3400 ppm for most saltwater pools.
Clean the Salt Cell
The salt cell, or chlorine generator, keeps your pool clean. Before closing the pool for winter, remove and check the salt cell. Drain any water from it and clean it with a mild acid solution or the cleaner your manufacturer suggests if you see dirt or buildup.
What are the common mistakes to avoid when winterizing your pool?
As a pool owner or a pool closing expert, here are some mistakes you should avoid during winter pool shutdown.
- Neglecting to clean the pool can lead to algae and debris buildup.
- Not lowering the water level enough can cause damage from freezing.
- Failing to drain and store pumps and filters properly can lead to ice damage.
- Skipping shock or algaecide can result in poor water quality when reopening.
- A flimsy or improperly secured cover can allow debris and animals to enter.
- Hurrying through winterization can lead to overlooked steps and potential issues.
Frequently Asked Questions
How much does it Cost to winterize a pool?
The average cost of pool winterization ranges from $200 to $300. Winterizing an in-ground pool costs about $250, while an above-ground pool costs about $150.
What is the best method for winterizing an in-ground pool?
To winterize an in-ground pool, remove as much water as possible. Then, add antifreeze to the pipes to prevent freezing. Drain all the equipment and store it safely to protect it from the cold during winter.
What chemicals do you need to winterize a pool?
Before closing the pool, you can add chlorine shock and algaecide. These chemicals help treat the water and keep it clean over the winter.
Is it possible to winterize an in-ground pool without a cover?
Yes, you can winterize your in-ground pool without a cover. However, it increases the chances of dirty water, damage to the equipment, and the pool structure freezing. Covering the pool helps protect it better.
