Pool winterizing resources are available in several parts. This third installment deals mainly with what to do during the winter.

  • It is normal to add water to your pool throughout the winter months due to evaporation. Lift your cover often, check your water level and add as necessary.

  • If your cover is waterproof, water will accumulate on the top from winter rain. When the water level reaches 1 to 2 inches in depth, then it is time to pump most of it off. It is recommended to leave a film of water on water tube type covers to keep them from whipping about in the wind. When you pump the water off your cover make sure you replace the water in the pool with a garden hose while you are pumping the cover off. If you do not keep your water level up high then there is a good possibility that your liner will float and wrinkles could develop on the bottom and/or sides of your liner. A shifting of the bottom can also occur.

  • Do not try to break the ice on your cover. The sharp edges might cut the cover.

  • Start the motor at least once each month for no more than 3 seconds. This will help prevent scale from accumulating and binding up the impeller and motor shaft.

  • Again, never drain the water from your pool and always keep your water level high. Remember when you pump water off your cover always have a garden hose filling your pool at the same time at the same rate as you are pumping your cover off.
