How Long Should I Run My Salt Chlorinator In Winter

How Long Should You Run Your Salt Chlorinator in Winter?

Winterizing your pool is crucial to protecting it from damage and ensuring it's ready for the next swimming season. But what about your salt chlorinator? Should it be running all winter, or can you shut it off? The answer isn't a simple yes or no, as it depends on several factors. Let's dive into the details.

Factors Affecting Salt Chlorinator Winter Run Time

Several factors influence how long (or if) you should run your salt chlorinator during winter:

1. Your Climate

• Freezing temperatures: If you live in an area with consistently freezing temperatures, keeping your chlorinator running might not be necessary, and could even be detrimental. Frozen pipes and equipment are a serious concern.
• Mild winters: In regions with mild winters, where the temperature rarely drops below freezing, running your chlorinator at a lower setting could maintain a minimal level of sanitation. This helps prevent algae growth and keeps the water chemistry balanced.

2. Pool Usage

• Complete closure: If your pool is completely covered and closed for winter, you likely won’t need to run your chlorinator. A covered pool is less susceptible to algae growth and contamination.
• Occasional use: If you plan on using your pool occasionally throughout the winter, even if for just a short period, keeping the chlorinator running at a lower setting will help maintain water quality and prevent the need for a significant shock treatment when spring arrives.

3. Pool Type

• Inground vs. Above Ground: Inground pools are generally more susceptible to damage from freezing temperatures compared to above-ground pools. This might impact your decision on whether to run the chlorinator.
• Material: The material of your pool (concrete, fiberglass, vinyl liner) also matters. Some materials are more vulnerable to winter damage than others.

4. Water Chemistry

Maintaining proper water chemistry is key, even during the winter months. While your chlorinator isn't running, you'll need to monitor your water chemistry regularly and adjust accordingly.

Recommended Practices

• Consult your owner's manual: Always refer to the manufacturer’s instructions for your specific salt chlorinator model for winterization guidelines.
• Lower the output: If you choose to run your chlorinator during winter, consider significantly lowering the output. You'll still need some level of sanitation but excessive chlorine production is unnecessary and wasteful.
• Regular checks: Regularly check your water chemistry, even if the chlorinator is running at a low setting.
• Consider a winterizing kit: Many pool supply stores offer winterizing kits that contain chemicals to help balance and protect your pool water during the winter months.

When to Turn Off Your Salt Chlorinator

Generally, it's best to turn off your salt chlorinator when:

• Freezing temperatures are consistently expected.
• Your pool is completely closed and covered for the winter.
• You have properly winterized your pool following the manufacturer's recommendations.

Conclusion

Ultimately, the decision of how long to run your salt chlorinator in winter depends on your unique circumstances. Carefully consider your climate, pool usage, pool type, and consult your owner's manual before making a decision. By following these recommendations, you can help protect your pool and equipment and ensure it's ready for use next spring.
