Most swimming pools include a freeze protection mechanism that activates when the temperature reaches near freezing of 32°F. Unfortunately, the freeze protection will not activate during power outages or extremely cold temperatures. When this occurs, it is critical the pool equipment gets winterized. The purpose of winterizing your pool is to remove all water from the above ground plumbing and equipment. Winterizing will not 100% guarantee a problem with your pool will not exist after a major freeze and/or power outage, but it will help prevent major damage and lessen the severity of damage to your pool equipment.
