Winterizing Your Pool: It’s Time!

We experience a delayed winter in the sunny Southland, but the time has finally come to winterize our Southern California swimming pools. Chances are, you may not use your pool for three months or more; so with that in mind, take the time to complete all of the following tasks:

Winterizing your Pool: Check the Water

First, check for swimming pool leaks to prevent potential freezing damage; then, test the water for quality to ensure the water will be safe once spring is here; and finally, check the water level to be sure it isn’t too high or too low. Continue to perform chemical treatments until the day you cover the pool; this will reduce the work you have to do before using it again in the spring. Also, if you pool has a skimmer closure, leave the water at the summer level if the cover is solid, and drain the water level to 2” under the bottom of the skimmer if the cover is mesh.

Winterizing your Pool: Filter Care

Filter care is a somewhat more intricate process. If you have a sand filter and the pool has a bottom or main drain, change the filter valve position to “waste” to lower the water level for winter. Then, clean the sand for next season by backwashing the filter before your water level goes below the skimmer opening. You may also want to hook up a manual pool vacuum and clean any debris while your filter is in the “waste” position. This allows you to clean the bottom and drain the water the same time. However, you should not vacuum the pool with your valve set to the “backwash” position.

Have a cartridge or element pool filter? Just remove the unit(s) and clean them.

Winterizing your Pool: Covering the Pool

Winterizing your pool water is as important as covering the pool. Before you cover your pool for the winter, our Temecula pool company can advise whether it’s necessary to purchase a winterizing chemical kit.

There are many good pool covers on the market, both lay covers and safety covers. Your lay cover should be large enough to rest on top of the water; a safety cover should be able to be stretched tightly over it. Many experts recommend a safety cover for those with young children.

Southern California swimming pools face less winter weather risks than pools elsewhere in the country, but winterizing is necessary nonetheless. Follow these steps for winterizing your pool, and enjoy a more pleasant first swim in the spring!
