How to Get the Air Out From Under the Lining of the Swimming Pool

Empty the Pool

• You can sometimes fix this problem by just draining the pool and adjusting the liner yourself. The pressure of the water should help readjust the liner and push it back into place as you maneuver it around. While the pool is refilling, watch the liner to make sure the water is pushing out the wrinkles. If it doesn’t, stop the water flow into the pool and hop in to begin pushing the liner back into place. Begin in the center of the pool and work your way out, pushing each wrinkle and air bubble against the wall of the pool. If you have never emptied a pool before, it is best to have a professional do it for you. If done incorrectly, it can damage your pool.

Use a Plunger

• You can use a plunger to remove small air bubbles or wrinkles from the lining of your swimming pool without having to empty the water. Take the plunger and place it directly above or below the wrinkle or air bubble. Press up and down on the plunger to remove the air trapped underneath the liner. Depending on the size of the air bubble, you may need to gradually plunge away the trapped air and repeat several times. When placing the plunger, make sure not to place it directly on the air bubble, as it could make the problem worse.

Prevention

• When you first install in a new liner for your pool, watch it as you fill the pool with water to catch any wrinkles that may form. If you notice any, move the liner away from the wrinkle with your hands. Continue to pull the liner up and away from the wrinkles to keep them at bay. As the pool fills, the weight of the water should allow the liner to settle into position against the sides and floor of the pool.

Considerations

• If you have drained the pool, it is best to try to remove any air bubbles or wrinkles on a warm, sunny day because the heat may make it easier to maneuver the liner. If you have a lot of wrinkles to remove, more than one pair of hands will make the job go faster.
