You have many responsibilities as a pool owner, and knowing when to replace your pool liner is one of them. These liners get a lot of wear and are always under pressure. Periodically, they need to be replaced, and it could happen before the recommended time for liner replacement.

Here’s how to tell when it’s time for a new pool liner:

Looking at the Signs

There may be a wrinkle or two here and there in the pool liner, and most pool owners don’t pay too much attention to them. However, wrinkles can be a sign that you may need a new liner. If you notice a texture change, it may be time for a new liner. Wrinkles in the liner can indicate that the chemicals in the water have not been well maintained. Wrinkles can lead to the liner’s vinyl being torn more easily.

Another sign is that you have a leak in your liner. A leak can cause a lot of problems, especially as the water leaks out and costs more money. If you want to find the leak, look around the lights, stairs, cleaner line, and corners to see if there is a tear there. You most likely have a leak if you see that the pool is losing water faster than usual.

Fading of the pool liner can also be a sign that it should be replaced. Frequent sun exposure will fade a pool liner, and this will make its vinyl brittle and hard. When vinyl gets brittle, it is more likely to form cracks and start to leak. If you start the season with a highly faded pool liner, it may be time to replace it before you fill it.

The Age of the Pool Liner

Typically, liners can get brittle when they are approximately five to seven years old. However, depending on the type of liner, it could last as long as 12 years. The vinyl that makes up the liner will come with a thickness measurement in millimeters. The higher the number, the thicker the liner is. Thicker liners will last longer. Most pool liners come in 20mm, 27mm, and 28mm sizes.

Changing Your Liner

If you’ve noticed some of these signs that your pool liner may need to be replaced, plan the time of the year that you’d like to replace it. It’s always best to get a new liner when it’s warm, as cool weather can cause the liner not to adhere as well as when it’s warm.
