As the temperatures start to drop, properly winterizing your above-ground pool is essential to protect your investment and make spring opening a breeze. Skipping steps or rushing the process can lead to costly repairs, so here’s a straightforward guide to get it right.
First, thoroughly clean your pool. Skim debris, vacuum the floor, and brush the walls. A clean pool prevents staining and algae growth while it’s closed for the season. Next, balance the water chemistry. Adjust the pH, alkalinity, and calcium hardness to recommended levels, then add a winterizing chemical kit. These treatments keep the water clear and discourage bacteria.
Lower the water level slightly below the skimmer, but don’t completely drain it—keeping some water helps stabilize the pool walls against winter weather. Remove ladders, hoses, and accessories, giving them a rinse before storage. Disconnect and drain the pump, filter, and heater to prevent freeze damage. If possible, store smaller equipment indoors.
Installing a winter cover is the final step. Choose a sturdy, tight-fitting cover that won’t sag or blow away. Use a cable and winch or cover clips to secure it firmly. For extra protection, consider an air pillow under the cover to reduce pressure from ice expansion.
By taking the time to clean, balance, and secure your pool now, you’ll avoid headaches later and enjoy a smooth start to swimming season next year. Winterizing may take a few hours, but it saves time, money, and stress in the long run.
