How to Remove Wrinkles from a Pool Liner

You are here because you are probably wondering why your pool liner has been lining up away from the wall. Well, worry no more because it’s an issue that affects countless swimming pool owners all across the world today. While pool liner problems are not easy to diagnose, you will find it easy to do so when you have the right information.

Fortunately, this guide takes a look at all the common pool liner lining up away from wall aspects that you have to consider.

Causes of Pool Lining Up Away from Wall

Usually, the most common cause of your pool lining up away from the wall would be due to issues such as heavy rainfall. When the water seeps through and gets behind the wall, it may cause it to start pulling away.

In some cases, the issue occurs if your area is prone to heavy rainfall, and water regularly gets through to the wall behind. Even if water getting behind the wall is a rare occurrence, its an excellent example of what to expect.

The vinyl liners can float, and the fibreglass pools can come right out of the ground. If the water gets through the pool liner, the seal will become compromised and lead to the development of wrinkles. Plus, it may also cause the liner to develop soft spots.

If this is the issue, then the liner might lift up, and float through the water. If such an issue occurs, don’t panic, stay calm because finding a suitable solution is easy. Mother nature might be the issue, and the good thing is that you can still place it back if the liner is in good condition.

Things You Can Do Stop Such Issues

The first thing you should do is to determine the presence of the issue, and find ways to address it right. These steps involved in the process include:

  • 1. Never drain the pool. Doing so can lead to various structural complications which can be a hassle to fix.

  • 2. Reduce the pool water level to normal, because the water can seep through the liner when it overfills.

  • 3. Find the “vacuum pipe” and determine if the water is free flowing. If the pipe has a blockage, then find a way to unblock it. Then, let it drain the water automatically behind the liner.

  • 4. Get a pool broom, and use it to push the liner to its original place. Do this, as the water drains behind the liner section.

  • 5. Invest in the assistance of a professional service provide to help you determine if you have placed the liner correctly.

Understanding How Pool Liners Work?

You can install pool liners by fastening them to the top section of the pool. Then you can hold them tightly in position by using the weight of the water. When you first install the pool liner, certain air pockets of air often remain in the pool liner. However, you have to remove the pockets of air by using a vacuum.

Then, add water to the pool, and the weight of the water will help hold the liner in the right position. Whether water seeps behind the liner due to flood or overfilling, the water pressure will equalize on either side of the line. And, this can cause the liner to move.

It’s a complication people commonly refer to as a “floating” liner. Issues relating to groundwater are not unique to these types of liners. That said, ground water will also lift entire pools out the ground, if the surrounding drainage is not of suitable quality.

More so, the fibreglass style pools also feature concrete shells that might “pop up” or move when you experience severe water exposure issues. A floating liner features fastening on the top section. However, some water underneath the wrinkles might start to come up.

Plus, the corners of the wall to the floor, and the deep end section might be “spongy” and “soft.” When this occurs, then it might be time to find ways to remove the water. Once you remove the water, it will start draining away slowly.

However, you have to ensure that you set up the liner correctly during this time. You can do this by using a pool broom, which you can use to move the liner outward to the wall. Its unique because the water drains away from the rear section of the liner.

The only challenge is that this process might require a few weeks for you to achieve the best results. Plus, it also depends on the amount of groundwater present below the pool liner.  Furthermore, you can also consider removing the water by using a “vacuum pipe.” That said, some pools don’t come with vacuum pipes, and you may have to adjust to the same accordingly.

You may also have to get in touch with a local professional pool service to help drain and refit the pool liner as required. They might also provide useful advice you can use as a preventative measure for such issues in the future.
