Introduction
As temperatures drop and the swimming season comes to an end, properly winterizing your pool becomes one of the most important tasks for homeowners in the U.S. Without adequate preparation, freezing temperatures can cause severe damage to pool surfaces, plumbing, pumps, and filters — resulting in costly repairs next spring.
This comprehensive guide covers winter maintenance methods for all major pool types found in American homes — including in-ground, above-ground, and functional pools like hot tubs, infinity pools, and natural pools. It also lists the tools and accessories needed for each maintenance step, many of which can be provided or customized by Yousky®, a professional manufacturer of pool cleaning equipment, steel frame pools, pumps, and pool accessories.
