As the days grow shorter and temperatures dip in the Triangle, many pool owners start thinking about winterizing their aboveground pools. While North Carolina winters are generally mild, they can be unpredictable, with occasional freezes that can damage your pool if it isn’t properly prepared. Proper winterization protects your investment, keeps water clean, and ensures a smoother reopening in the spring.

Rising Sun Pools has been helping homeowners across central North Carolina enjoy safe, beautiful pools since 1972. Our step-by-step winterization guide will help Triangle residents protect their aboveground pools through the colder months.

1. Clean Your Pool Thoroughly

Before you close your pool for the season, start with a deep clean. Removing debris, algae, and dirt now makes spring reopening much easier.

Steps:

– Skim the surface to remove leaves, twigs, and bugs.
– Brush the walls and floor to dislodge algae and grime.
– Vacuum the pool to remove any debris that has settled.
– Check the filter and clean it thoroughly; a clean filter reduces stress on your system.

These simple steps prevent staining and keep water chemistry more stable during the winter months.

2. Balance the Water Chemistry

Even during winter, water chemistry matters. Properly balanced water prevents corrosion, scaling, and algae growth while your pool is closed.

Key areas to check:

• pH: Keep between 7.2–7.6
• Alkalinity: Maintain 80–120 ppm
• Calcium hardness: 200–400 ppm
• Chlorine or sanitizer: Bring levels to the high end of recommended ranges to prevent algae growth

Adding a winterizing chemical kit designed for aboveground pools can help maintain clarity and prevent bacterial buildup while your pool is not in use.

3. Lower the Water Level (But Don’t Drain Completely)

Water expands when it freezes. If your pool is filled too high during a hard freeze, that expansion can put immense pressure on walls, seams, and your liner, potentially causing cracks, tears, or structural damage.

Here’s what to do:

– Lower the water to 4–6 inches below the skimmer opening (or follow your manufacturer’s specific recommendation).

– Don’t drain your pool completely unless you’re using a specialized air pillow system or your cover requires it.

– Leave enough water to protect the liner. An empty pool can lead to a dried-out, brittle liner that cracks or shrinks.

In the Triangle’s relatively mild climate, keeping water in your pool through winter actually helps. It weighs down the structure, prevents wind damage to the liner, and keeps vinyl supple.

4. Drain and Store Pool Equipment

Your pool’s pump, filter, and other equipment are at risk during freezes. Drain all water and store equipment in a dry, protected location.

Steps:

– Disconnect hoses and remove the pump, filter, and heater (if applicable).
– Drain water completely and store indoors or in a shed.
– Blow out water from lines using a shop vac or air compressor to prevent freezing.

This precaution keeps your investment safe and avoids costly repairs in the spring.

5. Install a Winter Pool Cover

A quality winter cover is essential for protecting your aboveground pool during North Carolina’s unpredictable winters.

Tips for covering your pool:

– Use a tight-fitting, durable cover to prevent debris from entering.
– Secure with straps or water bags to keep the cover in place during windy days.
– Ensure the cover has a drain or sump pump system to avoid water pooling, which can stress the cover or pool walls.

A good cover reduces maintenance work and protects your liner, making reopening in spring much easier.

6. Add a Pool Cover Pump

Even with a winter cover, rainwater and snow can accumulate. A pool cover pump removes excess water and prevents the cover from sagging or collapsing.

– Place the pump in the center of the cover.
– Check periodically after heavy rain or storms.
– Keep the water level under the cover slightly lower than the pool water itself.

This simple step can prevent structural damage and reduce cleanup time in the spring.

7. Consider Freeze Protection Accessories

While the Triangle usually has mild winters, sudden cold snaps can occur. Aboveground pools benefit from freeze protection devices, such as:

– Floating freeze balls that absorb expansion pressure
– Insulated covers or foam-filled pool noodles along the edges

Even inexpensive additions can save significant repair costs and extend the life of your pool.
