If you want to keep your winter pool covers tight, flat, and safe all season, check out VEVOR Pool Cover Water Bags. There are small kits for home pools and full-perimeter sets for bigger in-ground pools. These weighted tubes help prevent wind lift, protect liners, and keep debris from entering the water. Pick sizes and amounts that work with the shape of your pool to make closing and opening it easier every year.
A safe cover and the right amount of padding around all four edges of your pool are the first things that will keep it safe this winter. The VEVOR water tubes for pool covers that come with them are designed to lie flat on the deck, hug the fabric, and prevent water from leaking even when temperatures change. Whether you close a small above-ground pool or a large in-ground one, you can adjust the size, spacing, and materials to fit your environment and the amount of wind you get.
Before placing ballast around your winter cover, assess your pool’s size, shape, and level of wind exposure. Ensuring the bags are properly sized and spaced helps keep the cover secure, protects the liner, and reduces the need for mid-season adjustments.
First, measure the pool's full edge, including any steps or smooth corners. Most people put the first row of pool cover water bags a few inches from the edge of the deck. This way, the bags sit fully on the deck and overlap the cover. For rectangular pools, divide each side's length by the width of a single bag to estimate how many bags you’ll need. In places where the cover likes to lift, free-form and kidney shapes may need a few extra pieces in tight, curved spots.
Consider purchasing an extra set so you can add additional weight to wind-facing sides or around raised walls and spa sections if needed. Placing pool cover water bags evenly along each section makes it easier to identify any low or underfilled areas during a routine inspection.
Adding different amounts of water to each bag will change how well the cover stays in place during storms. Filling each bag slightly below the manufacturer’s recommended maximum allows for expansion during freezing temperatures while still providing sufficient weight to withstand strong winds. Putting two rows of water bags for a pool cover next to each other and spacing them evenly creates a stable barrier that keeps trash out and prevents the cover from rising.
If you have a long, narrow deck, you might want to mix standard and double-chamber designs to avoid overcrowding the walking area. After major storms or heavy rainfall, check water levels to ensure evaporation, leaks, or accidental movement haven’t reduced stability around corners and ladder openings.
An oval-shaped outdoor pool might only need one row of medium-sized bags along each side, plus a few shorter pieces to fill in the gaps. For larger in-ground installations, especially those with long, deep ends, it's often best to have two rows of water bags running parallel to each other on the side that gets the most wind.
Custom pools that aren't straight might need more trial and error in the first year. It's easy to repeat a successful plan next year if you mark where each row goes on a simple sketch. In areas with heavy rainfall, placing a denser row of pool cover water bags along the wind-facing side helps prevent leaves from lifting the cover and pushing dirty water back into the pool during cleanup.
Before you close the pool, lower the water level to the level suggested by the maker of your cover and equipment. Then lay out the bags, making sure they fit and that the hose can reach them. You can fine-tune the covering and move weight around without having to drag whole units across the deck when you fill in stages.
A simple list of how many pool cover water bags you use, how full you fill them, and where you store them when the season is over will help you close your pool cover more quickly and keep it closed for longer. It's also helpful to change the caps regularly so the older ones don't weaken.
The materials and construction of your pool cover water bags are just as important as the quantity you purchase. Look for heavy-duty vinyl or reinforced PVC walls that won't puncture from grit, twigs, or rough concrete. Welded seams will also keep the walls tight through many freeze-thaw cycles. Picking types that claim to be UV- and cold-resistant can help keep them from cracking, fading, or becoming stiff, especially on decks that get a lot of sun or in places where temperatures change a lot.
If you use water bags to protect the pool cover on rental properties or holiday homes, building them to last gives you peace of mind when you can't be there to check the levels often. When combined with compatible swimming pool cover water bags or water tubes, these features help create a perimeter system that delivers reliable performance with minimal maintenance throughout the season. Attaching strong pool cover water tubes to the layout of a pool cover can complement bags along the long sides or at ladder cutouts.
There are different kinds of pool cover water bags from VEVOR, so you can find one that fits almost any pool. At reasonable prices, thick materials, reliable valves, and large sizes let you carry the weight you need without constantly refilling. Pick the sizes that work for your deck, match them to your cover, and place your order today to make opening and closing easier.
