Common Mistakes When Winterizing Pools in Texas and How to Avoid Them

Jan 20, 2026

Winterizing your pool in Texas may seem unnecessary due to the mild winters, but it's a vital step to ensure your pool remains in excellent condition. However, many pool owners make common mistakes during this process. Let's explore these errors and learn how to avoid them.

Neglecting to Balance Water Chemistry

One of the most critical steps in winterizing a pool is balancing the water chemistry. Many pool owners skip this step, thinking that it's not necessary during the colder months. This mistake can lead to corrosion, scaling, and algae growth. Testing the water and adjusting the pH, alkalinity, and calcium hardness levels will prevent these issues.

Failing to Clean the Pool Thoroughly

Another common error is not cleaning the pool thoroughly before closing it for the winter. Leaving debris, algae, or dirt in the pool can cause stains and other problems. It's essential to vacuum the pool, brush the walls, and skim the surface to ensure it's spotless before winterizing.

Additionally, don't forget to clean the pool filters. Dirty filters can lead to poor circulation and water quality issues. Make sure to backwash or clean cartridge filters to maintain their efficiency during the winter.

Improperly Lowering the Water Level

Lowering the water level is a critical part of winterizing, but doing it incorrectly can lead to problems. Some pool owners lower it too much, exposing the pool liner to the elements, which can cause cracks and damage. Keep the water level just below the skimmer to protect the liner and plumbing.

Overlooking Pool Equipment Protection

Protecting pool equipment, such as pumps and heaters, is often overlooked. Failing to drain and store these components can result in freeze damage. Ensure that you remove, drain, and store the equipment properly to avoid costly repairs.

  • Drain all water from pumps, filters, and heaters.
  • Store equipment in a dry, sheltered area.
  • Use pool antifreeze in pipes to prevent freezing.

Ignoring Pool Cover Maintenance

Finally, many pool owners neglect the maintenance of their pool covers. A damaged or improperly secured cover can lead to debris accumulation and potential safety hazards. Regularly check for tears, ensure it's tightly secured, and remove any debris that collects on top.
