Winterizing Gunite Pools
Winterizing your gunite pool is a critical maintenance step that protects it from the harsh effects of freezing temperatures and ensures a smooth reopening in the next swimming season. At Harpeth Valley Hardscape, we know how important it is to properly prepare your pool for winter to avoid costly damage and maintain its longevity. Follow this detailed, step-by-step guide to effectively winterize your gunite pool.
1. Balance the Water Chemistry
About a week before closing your pool, it’s essential to balance the water chemistry to prevent damage to the gunite surface and pool equipment.
- pH: Adjust the pH to between 7.2 and 7.6.
- Alkalinity: Maintain alkalinity levels between 80 and 120 ppm.
- Calcium Hardness: Ensure calcium hardness is between 180 and 220 ppm.
Balancing the pool’s chemistry helps protect the pool’s surfaces from scaling and corrosion during the winter months.
2. Thoroughly Clean the Pool
Cleaning the pool before closing is crucial to avoid algae growth, stains, and debris buildup over the winter.
- Skim: Remove any leaves, twigs, or debris floating on the water’s surface.
- Brush: Scrub the pool walls and floor to eliminate dirt and algae.
- Vacuum: Vacuum the pool thoroughly to remove any remaining debris.
- Clean Filters and Baskets: Empty skimmer baskets, clean the pump basket, and backwash or clean the filter system.
A clean pool at closing prevents stains and makes opening your pool in the spring much easier.
3. Lower the Water Level
Lowering the water level is essential to prevent freezing water from damaging the pool’s plumbing and tile work.
- Mesh covers: Lower the water 12-18 inches below the skimmer.
- Solid covers: Lower the water to just below the skimmer.
Avoid draining the pool entirely, as this can cause structural damage to the gunite due to shifting ground pressures.
4. Add Winterizing Chemicals
Winterizing chemicals are necessary to keep the water clean and prevent algae and bacteria growth during the off-season.
- Algaecide: Prevents algae growth over the winter.
- Shock: A chlorine shock treatment kills bacteria and any remaining contaminants.
Follow the manufacturer’s instructions for distributing chemicals evenly throughout the pool for effective protection.
5. Protect the Skimmer, Pipes, and Equipment
One of the most critical steps in winterizing your pool is protecting the plumbing and equipment from freezing, which can lead to expensive repairs.
- Drain Equipment: Drain all water from the pump, filter, heater, and chlorinator to prevent freezing.
- Blow Out the Lines: Use a shop vac or air compressor to blow air through the plumbing lines, removing any remaining water.
- Plug the Lines: Install expansion plugs to keep water from re-entering the pipes during winter.
- Antifreeze: In colder climates, you may want to add pool-grade antifreeze to the plumbing lines for additional protection.
Properly draining and securing the plumbing helps avoid burst pipes and damaged equipment caused by freezing temperatures.
6. Cover the Pool
Using a quality winter pool cover is vital to keeping debris out of the pool and protecting it from the elements.
- Safety Covers: Opt for a mesh or solid safety cover that provides security and keeps debris out while supporting the weight of snow or ice.
- Proper Fit: Ensure the cover fits tightly and is securely fastened to withstand harsh winter weather conditions.
A well-secured pool cover reduces the amount of cleaning needed when reopening the pool in the spring.
7. Regularly Check the Pool Cover and Equipment
Even after winterizing, it’s important to periodically check on the pool and equipment throughout the winter.
- Pool Cover: Ensure the cover remains secure and free from tears or damage.
- Water Levels: Check the water level periodically, ensuring it doesn’t rise too high, which can stress the cover or the pool walls.
- Equipment: Inspect exposed equipment for any signs of leaks or damage that could worsen over the winter.
Performing occasional check-ins during winter can help you catch small issues before they become costly repairs.
Conclusion
Winterizing your gunite pool is an essential process that not only protects your pool from the risks of freezing temperatures but also makes for a hassle-free spring opening.
