While most of Florida enjoys swim weather year-round, many homeowners in Port Charlotte, Punta Gorda, and North Port choose to shut down their saltwater pool systems during the cooler months — especially if they’re seasonal residents or “snowbirds.” But improper shutdown can damage your chlorine generator, corrode fittings, or cause costly start-up issues later.
Here’s a complete guide on how to safely store and maintain your salt system through the winter months.
1. Decide Whether to Fully Shut Down or Just Scale Back
In Charlotte County, true “winterization” isn’t always necessary because freezing is rare. But scaling back your salt system for a few months can save energy and extend cell life.
Choose one of two options:
- Partial shutdown: Lower system output to 10–20% and reduce pump run time.
- Full shutdown: Turn off power, clean the cell, and store it indoors if you’re leaving the home for the season.
Local Insight: If you’re in Rotonda or coastal areas where night temps dip into the 50s, even a partial reduction helps minimize wear.
2. Clean the Salt Cell Before Storage
Before you disconnect anything, inspect the cell for white scale buildup — usually calcium.
Steps:
- Turn off the system and disconnect the cell.
- Rinse gently with a garden hose.
- Soak the cell in a 4:1 mix of water and muriatic acid for 15 minutes (use a plastic bucket).
- Rinse thoroughly and let it dry completely before storage.
Pro Tip: Always add acid to water, not water to acid. And never scrub metal plates with hard brushes — it shortens cell life.
3. Check and Balance Pool Chemistry
Even when your salt system is off, the pool water chemistry must stay balanced to prevent corrosion or algae blooms.
- Chlorine: 1–3 ppm (use liquid chlorine or tablets as backup).
- pH: 7.2–7.6
- Alkalinity: 80–120 ppm
- Cyanuric Acid (Stabilizer): 30–50 ppm
If your pool isn’t in use, you can reduce test frequency to every 2–3 weeks, but don’t skip entirely.
4. Drain and Dry the Equipment
If you’re shutting down completely:
- Disconnect flow sensors, unions, and fittings.
- Drain any residual water from the cell and plumbing lines.
- Store the cell indoors in a dry, climate-controlled spot.
- Leave unions lightly capped to keep out insects and debris.
Bonus Tip: For pools near the Peace River or other humid zones, consider adding silica gel packets to storage containers to prevent corrosion.
5. Protect Electronics and Power Centers
Electronics are especially vulnerable to Florida humidity during long shutdowns.
- Keep the control panel cover closed.
- Spray electrical connectors with dielectric grease.
- If possible, use a surge protector to prevent power spikes during storms.
If you’re leaving your home for several months, unplug the system from its power source.
6. Restarting in Spring
When the weather warms up:
- Reconnect the salt cell and inspect for cracks or corrosion.
- Refill pool to normal water level and test salinity.
- Adjust salt to manufacturer specs (typically 2,800–3,400 ppm).
- Run the system for 24 hours and confirm chlorine production.
If your water appears cloudy or the system shows “low salt,” recalibrate using a digital salt meter before adding more.
7. Common Mistakes to Avoid
- Leaving saltwater in the cell: Can crystallize and corrode plates.
- Skipping pH checks: Acidic or alkaline water causes staining and scaling.
- Using pressure washers to clean the cell: Damages coating and sensor probes.
Final Thoughts
Proper salt system winter storage is simple but vital. A few hours of prep now can prevent thousands in equipment damage later. Whether you’re a year-round resident or a snowbird heading north, keep your system dry, clean, and covered — and you’ll have crystal-clear water waiting when you return.
