When you think of “winterizing a pool,” you might picture snow, ice, and heavy pool covers. But what if your commercial pool is located here in Texas, where freezing temperatures are uncommon? Even in this climate, taking steps to prepare your pool for the off-season is essential for protecting your investment, controlling costs, and ensuring a smooth opening when swim season returns.
Here’s what to keep in mind when winterizing a commercial pool in a non-freezing climate like Texas.
1. Adjust for Reduced Usage, Not Ice
In colder climates, winterization focuses on protecting equipment from freezing damage. In Texas, the priority shifts to managing reduced use and preventing off-season problems like algae growth, water chemistry imbalance, and unnecessary energy consumption.
It’s tough to keep a pool looking perfectly clean in the off-season, but it should always be maintained well enough to have curb appeal for residents and visitors.
2. Balance and Treat the Water
Keeping the water balanced during the off-season is just as important in Texas. Even when the pool isn’t being used regularly:
Test and adjust pH, alkalinity, and calcium hardness.
Apply a long-lasting algaecide to reduce the risk of blooms.
Shock the water before reducing circulation schedules.
This prevents costly clean-up when reopening.
3. Optimize Circulation and Filtration
Since temperatures rarely reach freezing, you don’t need to drain the pool or run equipment constantly. Instead:
Adjust pump run times to shorter daily cycles that still ensure proper circulation.
Backwash and clean filters to remove debris before lowering run times.
Keep skimmers, baskets, and strainers free of leaves and organic matter.
This balance saves energy while maintaining water clarity.
4. Inspect and Protect Equipment
Even without frost, equipment still needs attention:
Inspect pumps, heaters, and chemical feeders for wear.
Lubricate o-rings, seals, and valves.
Cover exposed equipment with weather-resistant covers to protect from rain, dust, or sun damage.
Preventative maintenance during the off-season helps avoid mid-season breakdowns later.
5. Protect Fresh Water Systems in Case of a Freeze
Even in Texas, rare cold snaps can cause significant damage if fresh water lines aren’t prepared. A commercial pool facility should take precautions for:
Bathrooms & Locker Rooms: Insulate exposed water lines, especially those near exterior walls. Keep doors closed and consider small space heaters in mechanical areas if a freeze is predicted.
Backflow Preventers: These devices are often exposed outdoors and are vulnerable. Wrap them with insulating covers or blankets, and if possible, install a protective enclosure.
Hose Bibs: Disconnect hoses, drain bibs, and insulate with covers to prevent cracking.
Fill-Spout Lines: If your pool has an auto-fill or fill line, make sure it’s drained or insulated to prevent ruptures. A frozen fill line can burst and cause flooding once temperatures rise.
Other Fresh Water Systems: Drain irrigation lines or fountains where possible, and ensure shut-off valves are accessible in case of emergency.
⚠️ Important Note: It’s essential to understand what your pool management contract does — and does not — include regarding freeze preparation. Some services may be built into routine maintenance, while others may require additional agreements or one-time service calls. Clear communication with your management partner ensures there are no surprises if a freeze event occurs. Also, it is always recommended to consult with a licensed plumber who specializes in winterization for a specific winterization plan for your facility.
6. Keep Safety Top of Mind
Just because the pool isn’t in daily use doesn’t mean it can be ignored:
Maintain proper fencing, locks, and signage.
Ensure lifeguard stands, diving boards, and ladders are secured or stored if not in use.
Conduct off-season safety inspections to identify repairs that can be made before reopening.
7. Plan for Budget and Reporting
The off-season is the perfect time for boards and property managers to review:
Maintenance reports from the past season.
Budget forecasts for upcoming equipment upgrades.
Any new compliance requirements or regulations on the horizon.
Proactive planning ensures the pool is ready — financially and operationally — for next year.
Final Thoughts
Winterizing a commercial pool in Texas isn’t about fighting ice every winter; it’s about protecting equipment, controlling costs, and staying ahead of problems.
