Freeze Protection: What Central Texas Pool Owners Should Know
Most modern pool systems in Central Texas and all our installed systems have automatic freeze protection, which typically activates when the air temperature sensor at the equipment pad reads around 38°F. One important note: freeze protection is triggered by that sensor, not the temperature shown on your phone’s weather app. Wind, sun exposure, and equipment location can cause meaningful differences.
When freeze protection is active, the system automatically turns the pump(s) on to keep water moving. Flowing water is the most effective defense against freeze damage.
Insulation Do’s & Don’ts
• Exposed plumbing can be insulated for added protection.
• Do NOT insulate pump motors, heaters, or heater exhaust vents. These components require airflow and heat dissipation—covering them can create a fire or equipment hazard.
• Any insulation should be removable and used only during freezing conditions.
If You Lose Power During a Freeze
• Remove drain plugs from pumps, filters, heaters, and other equipment that are above water level.
• Open any manual drain valves if present.
• This allows water to drain out and prevents freeze expansion damage.
• Plumbing below water level should generally remain closed unless directed otherwise by a professional.
Additional Best Practices
• Ensure valves are positioned for full circulation.
• Avoid shutting systems off during freezing weather unless advised.
• Partial circulation (spa only or select lines) increases risk—full circulation matters.
• When temperatures drop, running the system is almost always safer than turning it off.
Freeze events in Central Texas are usually brief, but damage happens fast when systems are improperly shut down, improperly insulated, or left full of standing water. Movement and drainage are your two best defenses.
