If your area is subject to frequent hard freezes...properly winterize your pool equipment and piping then secure the pool cover.
In milder climates...keep your pump running as you normally would to keep the pool water from freezing.
Above Ground Pools...are particularly susceptible to winter damage and require extra care and attention.
Spas should be enjoyed throughout the winter months...closing your spa is not recommended unless it will not be used for at least three months (i.e. in a vacation home).

Pool Fact: Water chemistry and safety are equally important in winter and summer.

Inground Swimming Pools

If your area is subject to frequent hard freezes...make sure the pool is clean and clear prior to closing.

  1. Properly balance pool water. Also add shock treatment (chlorinated or non-chlorinated).
  2. Lower the water level to below the skimmer.
  3. Clear pipes and equipment of water using a blower or compressor and plug the pipes at the pool.
  4. Add swimming pool antifreeze to the lines to prevent freezing.
  5. Place a Gizzmo* (or similar device) in the skimmer to seal it and absorb pressure from ice. Ask your local Pool Retailer for more details on the Gizzmo for your skimmer.
  6. Install your safety cover or winter tarp cover using water tubes to secure.

In milder climates...

  1. Make sure that the pump is running during periods of below freezing temperatures.
  2. Keep the water properly balanced and sanitized throughout the off-season months.
  3. Some pool owners also choose to install a Winter Cover or Safety Cover.

Pool Fact: Pumps should be kept running during freezing temperatures or completely drained during the winter to avoid a risk of damage to the pump, filter, heater, pipes, and any other in-line equipment.

Above Ground Swimming Pools

  1. Properly balance pool water. Also add shock treatment (chlorinated or non-chlorinated).
  2. When preparing to winterize the pool, do not drain water below the recommended level. NEVER DRAIN POOL COMPLETELY.
  3. Lower the water level to below the skimmer opening and plug return(s) in the pool. Install the skimmer faceplate cover.
  4. Clear pipes and equipment of water and insulate them. Remove and store your pump.
  5. Install the air pillow and then the pool cover.
  6. Store your pump, hoses, and other in-line equipment that can be removed.

Common reasons why above ground pool walls could collapse or fail:

  1. The skimmer catches water which then freezes, causing the skimmer to become too heavy for the wall to support. This eventually causes the wall(s) to collapse.
  2. An ice expansion pushes out against the walls, causing the walls to buckle under the immense pressure and weight of the ice.

Spa Fact: Spas are designed to run and be enjoyed throughout the winter months. However, it is recommended that you lower the water temperature when the spa is not in use.

Recommended Products:

Freezing can create costly damages to your swimming pool or spa. The best way to protect your pool or spa from freeze damage is to prevent it from happening. Properly winterizing your pool and following these tips can prevent freeze damage from destroying your backyard paradise. We recommend the following products to aid you in your freeze damage prevention.

Winterizing Kits for correct chemical balance throughout the winter months and protection of all non-mechanical elements of your swimming pool.

Blowers clear pipes and equipment of water prior to being plugged and insulated to protect them from the elements.

Skimmer Faceplate Covers prevent your skimmer from retaining water which can freeze and possibly damage the pool wall.

Gizzmos are designed for inground skimmer ice expansion protection.

Water Tubes and Air Pillows are used under winter covers for ice expansion prevention.
