A pool cover is essential for protecting an inground pool, especially during the off season. Whether you use solid covers, pool safety covers, or a winter cover, preventing a sagging pool cover is critical for pool safety and cleanliness. As pool owners, understanding the causes, solutions, and preventative steps is key to proper maintenance and extending the life of your cover.
Why is my pool cover sinking?
A sagging pool cover can result from multiple factors. Collecting snow, excess water, and debris on the surface all add extra weight that gravity pulls toward the center—the weakest structural point. When standing water or heavy debris accumulates in the middle, it can cause the cover to dip, form a puddle, or even lead to tears and holes. If strong wind pulls at an insecure edge, or if straps become loose, this can contribute to additional sagging or make it easier for water to collect. Improper installation, poor support, or simply not tightening the cover regularly can also invite these problems. Even during the winter months, when you’re tempted to just let things sit, it’s important to monitor your cover and its supports.
Essential tools and pool cover types
Understanding your cover and the right equipment is the first step in learning how to keep pool cover from sinking.
- Pool Safety Covers & Solid Covers: These provide security and durability but need to be supported properly at each edge.
- Winter Covers: These are designed for the cold season but are vulnerable to extra weight without air pillows or water bags underneath for support.
- Automatic Cover Pump / Manual Pump / Sump Pump: These devices are essential for removing water that collects on top of the cover. Connecting a garden hose to your pump can help drain away the water from the yard.
- Air Pillow: Placing a pillow beneath the cover creates an elevated center, helping prevent sagging and distributing weight evenly.
- Leaf Blower: This tool can quickly blow away debris, making it easier to keep the cover clear.
- Water Bags: These can be used to secure the edges of a winter cover, preventing wind from getting beneath and causing issues.
How to keep your pool cover from sinking and sagging
A well-maintained pool cover is crucial for keeping your pool clean and protected throughout the off-season. Follow these essential tips to prevent sagging and prolong the life of your pool cover.
1. Install your cover correctly
Lay your cover flat and connect each anchor point around the edge. Tighten straps to ensure the cover sits securely and evenly. Adjust as needed after storms or winds to keep the surface taught.
2. Use an air pillow or support system
Place an air pillow or support in the center before you install the winter cover. This will create a slope for water and debris to roll off, preventing extra weight from collecting in one spot.
3. Remove excess water routinely
After rainfall or snow, use a cover pump, either automatic or manual, to remove excess water before it becomes too much. Some pool owners also utilize a sump pump with a garden hose for faster draining. Removing water frequently keeps the cover from sagging and helps maintain security.
4. Keep debris off the cover
Use a leaf blower for light debris and a pool pole for larger pieces. Debris buildup adds weight and can lead to holes or tears, so clearing it quickly is essential.
5. Secure the cover’s edges
Use water bags or weights to secure the edges if you have a winter cover. This helps prevent wind from getting underneath and causing the cover to pull or lift.
6. Monitor water level
During the winter months, check that the pool’s water level isn’t too high or too low. Enough water supports the cover from underneath, helping prevent it from collapsing under the weight of snow or rain.
7. Address any signs of damage
Inspect for holes, tears, or loose straps. Early repair can stop problems from getting worse. Repair kits are available for minor damage; for extensive issues, replace the cover.
How to fix a sagging or sinking pool cover
A sagging or sinking pool cover can lead to messy cleanup, damage, and even water contamination if not addressed promptly. If you’ve been wondering how to keep the pool cover from sinking, here’s a step-by-step guide to restore your pool cover’s proper position and prevent further issues.
- Remove Water Immediately: Pump out water using your cover pump, then use a garden hose to drain the water away from the pool area.
- Clear Debris: Use a leaf blower or a pool net to remove debris, especially from the center.
- Adjust & Tighten: Pull the cover tight and retighten the straps at each anchor point.
- Check for Tears: Wet or cold weather can worsen damage, so repair or replace if necessary.
- Add Support: If possible, install an air pillow under the middle; it may be possible to do this even after opening the cover partway.
- Monitor Water Chemistry: If too much water gets through, maintaining proper water chemistry is important to avoid contamination. If your hot tub shares the same cover type or is nearby, use the same principles—support, remove water, and clear debris.
