How to Close an Above Ground Pool for the Winter

Do you own an above ground pool? If so, it’s just about time to start preparing for the winterization process. If you follow our eight-step winterization process you will be in great shape heading into the off season.

Step 1: TEST AND BALANCE THE WATER

Prior to closing your pool for the season, test the pool water with  water test strips for Ph (7.2-7.6), alkalinity (80-120ppm), calcium hardness(175-250ppm), and finally chlorine level (1-3ppm). To protect your pool from corrosion it is recommended to adjust the chemical balance based off of the tests performed. This will eliminate scale build up when the pool is closed.

Step 2: CLEAN THE POOL

Cleaning the pool is essential in this process. You will need to  vacuum and brush the pool walls and floor. All the way up to the top of the walls should be scrubbed. View our selection of brushes or pool cleaners.

Step 3: SHOCK THE POOL AND ADD WINTERIZING CHEMICALS

Now it is time to add the winterization chemicals. You will start this by shocking your pool. To do so, you will need to add three to five times the normal amount of chlorine. To prevent algae growth, you can use a polyquat algaecide. We would also suggest looking into purchasing a winter closing kit.

Step 4: RUN THE POOL PUMP AND CLEAN THE PARTS

After adding your winterizing chemicals, it is time to run the pool pump for at least one cycle before you manually clean the filter. Following, this is a great time to clean out the  skimmer and pump basket.

Step 5: LOWER THE WATER LEVEL

When winterizing an above ground pool, it is important to never drain the water completely. This would lead to the liner shrinking or shifting. The best way to go about this would be lowering the water to about 4”-6” below the skimmer in order to retain the proper amount of water pressure needed. The water pressure will assist in holding the liner in place and protecting the pool from polluting elements that may cause damage.

Step 6: WINTERIZE THE PUMP AND FILTER

In order to get the pump and filters ready for the winters, you should remove all drain plugs and then remove the pump. Keeping track of your materials by organizing will help in the long run. Following the manufacturer's guide for

your specific product will also help you tremendously. In the market for a new pump? Visit our page on above ground pool pumps.
