Winterizing Your Pool: What Pool Owners Need to Know in 2025

Pool winterizing - BC pools

Winterizing your pool is one of the most essential tasks for any pool owner. Proper winter care helps protect your pool and equipment from damage caused by freezing temperatures. If you live in Northwest Arkansas, where winters can be unpredictable, knowing how and when to winterize your pool can save you time, money, and hassle when warmer months return.

Understanding why winterizing is important, when to start the process, and the steps to follow will help keep your pool safe and in excellent condition throughout the cold season. With the proper preparation, you can avoid costly repairs and enjoy a smooth pool opening next spring.

Why You Should Winterize Your Pool

Failing to winterize can lead to costly problems. When temperatures drop, water left in pipes, pumps, or filters can freeze and expand, causing cracks or breaks. Pool surfaces may also suffer from algae buildup and debris accumulation during the cold months. According to the Pool & Hot Tub Alliance, the cost of repairing freeze damage can be several hundred dollars, making winterizing a wise investment.

Winterizing also means a cleaner pool comes spring. When you prepare your pool properly, it requires less cleaning and fewer chemicals to get it back to swimming condition. The process protects your equipment, reduces maintenance, and extends the life of your pool.

When to Start Winterizing in Northwest Arkansas

In Northwest Arkansas, the best time to start winterizing your pool is usually late October to early November. This period typically comes after the swimming season ends but before freezing temperatures arrive. The National Oceanic and Atmospheric Administration (NOAA) reports that the average first frost in this region happens around early November.

A good rule of thumb is to begin winterization when daily temperatures consistently fall below 65 degrees Fahrenheit. You can check local weather updates via NOAA’s website to plan your timing. Starting too early can waste chemicals and lower pool usage, while starting too late can risk freeze damage.

Step-by-Step Guide to Winterizing Your Pool

Pool - BC pools

Winterizing a pool involves several essential steps. Follow these to keep your pool safe through the cold months:

  1. Clean the Pool and Remove Debris
    Skim leaves, brush pool walls, and vacuum the floor. Removing debris helps prevent algae growth and staining.
  2. Balance Water Chemistry
    Test and adjust your pool water to the recommended levels. Aim for pH between 7.2 and 7.6, alkalinity between 80 and 120 ppm, and calcium hardness between 180 and 220 ppm. Balanced water protects the pool surface and equipment.
  3. Shock Treatment and Algaecide
    Add a chlorine shock to kill bacteria and algae, followed by an algaecide to prevent growth over winter.
  4. Lower the Water Level
    For in-ground pools, lower the water level about 4 to 6 inches below the skimmer to avoid freeze damage. Above-ground pools have different recommendations—always check your manufacturer’s instructions.
  5. Drain and Store Pool Equipment
    Remove pumps, filters, heaters, and other equipment that can freeze, and store them in a dry, safe place.
  6. Blow Out and Plug Pool Plumbing Lines
    Use an air compressor or shop vac to clear water from pipes, then plug them to prevent water from entering.
  7. Install and Secure a Pool Cover
    Use a sturdy winter pool cover to protect water quality and keep debris out of the pool. Pool pillows can help absorb ice pressure, especially for above-ground pools.

Equipment to Winterize and How

Properly caring for your pool equipment is key:

  • Pumps and filters: Drain completely and store indoors if possible.
  • Heaters: Turn off, drain, and cover or store inside.
  • Automatic cleaners and hoses: Remove and store.
  • Skimmers and baskets: Clean and leave in place or remove, depending on the type of your pool.

Failing to protect equipment can cause cracks, rust, or permanent damage from freezing water.

Pool Covers: Types and Benefits

Pool covers are your last line of defense in winterizing. They keep debris out, prevent algae growth, and protect water quality.

  • Solid covers: Block all sunlight, preventing algae growth.
  • Mesh covers: Allow water to pass through while keeping leaves and debris out.
  • Safety covers: Stronger, can hold weight, and prevent accidents.

Using a cover with pool pillows can reduce ice pressure on the pool walls.

Common Mistakes to Avoid When Winterizing Your Pool

  • Starting winterization too late or too early
  • Not balancing water chemistry properly.
  • Leaving water in pipes or equipment, causing freeze damage
  • Using a damaged or improperly secured pool cover
  • Skipping regular checks during the winter months
