Installing an above ground pool cover correctly is the single most effective way to extend its lifespan, reduce chemical usage, and keep your pool clean. A proper cover acts as a barrier against debris, minimizes water evaporation, and can significantly lower your energy costs by retaining heat. While the process might seem straightforward, paying attention to detail ensures the cover functions as intended season after season.
Preparing the Pool and Surrounding Area
Before the cover even touches the water, the pool must be pristine. Start by completely draining the pool using a submersible pump if you are installing the cover for the winter. Once empty, use a metal brush to scrub the interior walls to remove any algae or calcium deposits. Rinse thoroughly and allow the structure to dry completely to prevent mold from forming under the cover.
While the pool dries, clear the surrounding deck of any furniture, plants, or loose objects. Inspect the pool wall for any sharp edges or protruding screws that could puncture the cover during installation. Sand down any rough spots and ensure the top ledge is level; an uneven surface will create tension points that can cause tears once the cover is secured.
Measuring and Selecting the Correct Cover
Accuracy is critical when selecting a cover. Measure the diameter of your pool from the outer edge of the wall across the center to the opposite edge. If your pool is oval, measure the longest and shortest points. Always order a cover that is slightly larger than your measurements; this excess allows for a tight, drum-tight fit when the cover is secured.
Not all covers are created equal. Consider the material—polyethylene is standard for basic debris blocking, while vinyl laminated covers offer superior insulation for heat retention. If you experience heavy snowfall, look for a cover rated for snow loads, which will prevent the accumulation of water from turning into ice and damaging the structure.
Installing the Cover System and Accessories
Most modern above ground pools use either a cable and winch system or a strap system. For cable systems, begin by threading the cable through the eyelets around the perimeter of the pool wall. Use a cable tightener or winch tool to pull the cable snug, creating a uniform tension around the entire pool. The goal is to remove all slack so the cover behaves like a drumhead rather than a sagging tarp.
Once the cable is secure, center the cover over the pool. Align the cover's access point or zipper with the designated "top" of the pool. Attach the cover to the cable using the provided clips or clamps, spacing them roughly every 18 inches. For strap systems, simply hook the straps over the wall and tighten them evenly using the buckles, ensuring the cover lies flat without bubbling.
Anchoring and Final Security Checks
Wind is the primary enemy of a pool cover, making anchoring essential. Insert anchor stakes into the ground around the perimeter of the pool, pulling the cover taut as you go. If you are installing the cover for the summer and expect frequent access, you may opt for bungee cords or removable anchors that allow for quick entry without completely removing the system.
Before finishing, walk around the entire perimeter to check the tension. The cover should sound like a drum when tapped and should not ripple in light wind. Ensure the access point is sealed correctly, whether via a zipper seal or a dedicated ladder well that prevents water collection. A well-installed cover will shed rain and snow, keeping your pool water chemistry balanced and ready for use.
