How long does a pool liner last?

There will come a time when you have to consider replacing your vinyl liner, but it is one of the most important components of any pool.

Nevertheless, some factors, such as premature wear and tear and advancing age, can reduce the lifespan of a liner. In this article, we’ll talk about How long does a pool liner last?

What is the life span of a pool liner?

Vinyl pool liners typically last between 15 and 20 years, depending on whether you have an inground pool or an above ground pool. The average inground pool liner normally lasts six to ten years. The lifespan of underground liners is shorter, usually between four and nine years. Pool liners can last as long as 20 years if they are cleaned and cared for regularly.

Here are a few factors that can affect how long your liner will last

Overuse

Swimming pools are a great way to cool off and keep cool, especially during those hot summer days! The concept of “too much of a good thing” is a real one.

If your pool’s liner is worn excessively, it will age prematurely, and if it is used frequently, it will be more vulnerable to tears, scratches, and rips. If you notice rips or tears in your pool liners, repair them as soon as possible to ensure that pool water does not leak into the soil surrounding your pool.

pH unbalance and an excess of chlorine

In order pool maintain a safe and sanitary swimming pool, chemical balance are necessary. In any case, you must always use chemicals with care and ensure that they are properly inserted. In failure to do so, the vinyl will prematurely fade or degrade, dramatically reducing your liner’s lifespan. Chlorine and pH are the primary contributors to this problem.

Most pool owners add chlorine to the pool only after you have measured and diluted it in a bucket before adding it. It is not recommended to introduce chlorine directly to the pool since undissolved chlorine would bleach and eat away the liner. The vinyl liner of a pool, on the other hand, will wrinkle and shrink if it does not have enough chlorine, ultimately losing its shape.


Your pool water’s pH indicates how acidic it is. Chemical strips can be used to test your pool’s water chemistry, which will keep your liner healthy. pH levels in your pool should range from 7.4 to 7.6; anything above 7.8 will cause calcium deposits to form on the liner.


Pool maintenance

Your pool vinyl liner must be maintained to remain in good condition. Regular cleanings and maintenance of pool walls. Checks ensure that problems with your liner do not go unnoticed and worsen over time. The more severe the damage, the more expensive the repairs will be until eventually, you will have to replace the entire liner.

The liner of your pool should be thoroughly cleaned once a week and its chemistry should be tested three times a week. To avoid algae buildup, shock your pool every two weeks (more often if it is heavily used).

When you’re swimming, check your vinyl pool liner regularly for tears, bleached spots, or wrinkles. The pool owner can extend the life of your liner by performing these simple maintenance tasks.

Do not drain all the water

Never completely drain a pool with a vinyl liner. The vinyl liner pool owners should never be completely drained, especially if it’s inground pool liners. Liner integrity can be damaged in this way since it will bow and crack and lose its shape.

By refilling it, you risk making bubbles and wrinkles. Consequently, the pool vinyl liners are more likely to tear down the road. As a result, you should drain your pool a third at a time.

Ground Water Problems

Water can seep through the liner under high groundwater levels, causing it to float. When the groundwater recedes, the liner will eventually settle back down, but it could stretch, wrinkle, or come out.

The fit of the liner

Vinyl liners that are not fit specifically to your pool’s dimensions will not last as long as those that are. An incorrectly sized vinyl liner pool needs to be stretched into place. This may result in weak points in the liner and reduced lifespan if a new vinyl liner that was once 30mil thick is reduced to 15-20mil after installation.

How do I know when to replace my pool liner?

To understand that it’s time to change your swimming pool liner, you need to pay attention to a few things. Now let’s look at the most basic of them.

Rips and Cracks

When a pool liner begins to crack and rip, it is obvious that the liner must be replaced. Vinyl pool liners degrade with time as a result of a combination of UV radiation from the Sun and pool chemicals. Vinyl becomes brittle as a result. Liners that become brittle will begin to crack much more easily. This can lead to pool water leaking from the pool.

As UV and chemical damage is most prevalent near the surface of the water, these types of cracks generally occur there. You are likely to need a replacement liner in the near future if you notice your liner cracking or tearing around the waterline.

You do not have to replace your liner just because there is a small leak. Older liners are prone to leaks, but they can easily be repaired with a standard patch kit. However, if you notice several cracks in one place, or if you keep seeing rips all over the pool liner, you will definitely need to replace it immediately.

Loss of water

A crack or rip may not always be obvious, especially if it is below the surface of the water. The reason you should monitor leak water loss in your pool is that your liner beginning loses water faster if it is more than ten years old.

You can perform a simple test to determine whether your swimming pools are losing water due to leaks if you suspect it is. Fill a bucket with water right up to the level of the water in your pool and place it on the steps leading to the pool.

This test can determine if the pool is losing water in other ways than evaporation by comparing the rate at which water evaporates in the bucket and the rate at which water evaporates in the pool.

Compare the level of water in the bucket with the level in your pool after a few days. If your pool’s water level is lower than that in the bucket, you have a leak; otherwise, every drop of water you’re losing is purely evaporation.

The color fades or stains.

The color fades or stains as a result of UV and chemical damage. Most pool liners will resist fading as long as they aren’t in direct sunlight. Colored finishes on vinyl liners will fade over time, as well plasticizers that make them pliable.

It is the degradation of these plasticizers that results in pool liners becoming brittle, so a faded liner could mean it is starting to crack and tear soon. In the event your vinyl liner becomes badly faded, you should try a bucket test to check for leaks; if you find cracks or rips, you should replace your vinyl liner.

Stretch marks and wrinkles

It may happen that your liner begins to stretch after installation if you live in an area affected by groundwater issues. Liner wrinkles form as a result of this and will even be pulled out of track at the top of the pool.

You can try slipping the vinyl liner back into the top track of the pool if you notice it has begun to slip out. Putting the vinyl liner back in the track involves first heating it with hot water to make it more pliable, then lifting it and placing it back in the track.

You should replace your pool liner as soon as possible. If the vinyl liner won’t go back in or if the problem keeps occurring. Replacement is the only option in these cases since the problem will continue to worsen over time.

What Is The Best Time To Replace A Pool Liner?

The best time to replace your swimming pool liner is best performed in the fall or spring. It generally takes at least 2-3 weeks to replace an old liner. The pool owner can still enjoy a full season of swimming if you replace your liner in the fall or spring.

As retailers are not as busy during these months as they are during peak pool season, they will also generally offer better deals.

Getting started early with the liner replacement process of your pool is crucial if you plan on replacing it in the spring. In March or April, most people who intend to replace their pool liners in the spring begin their buying process.

In most cases, though, by this point, many swimming pool retailers have already booked a number of replacement liners and are unable to install them until the middle of summer. In order to ensure that you get your liner replaced before the swimming season begins, we recommend putting down a deposit for a new liner as early as possible, by the end of January.

How To Extend The Life Of Your Pool Liner?

Balance Your Water

Keeping your pool’s water chemistry balance within the recommended ranges slows down the natural deterioration of the liner. In addition to keeping the lining soft and supple as it ages, proper water balance prevents cracking.

The Right Sized Liner

When you purchase a replacement liner, make sure that the pool installer company removing the old liner empties the pool before measuring for the new one. To prepare the pool surface for its new liner, the installer will cut holes for the stairs, jets, and skimmer.

By doing so, they can get more accurate measurements and reduce how much stretching is required to place the new liner.

Patch Small Leaks

A leaky liner allows water to leak behind it, rusting the metal underneath, and, if left too long, damaging the concrete beneath. In the event that you wait too long to repair a leak, more damage will be done to the pool’s structure. Moreover, the liner may also become unrepairable if a small tear becomes a bigger one, growing to the point where it cannot be repaired.

Good Winter Cover

When you cover your pool during the winter, not only will it protect the liner from debris that could damage it, but it will also protect it from the UV radiation from the sun. Winterizing your pool during seasons of non-use can also help to prolong your liner’s life.

Do you have warranty pool liners today?

You should read the fine print of any warranty that comes with vinyl pool liners. A warranty usually loses value after the first few years if it is prorated. If your warranty covers 25 years, for example, only 10 percent of your replacement cost will be covered after 8 years.

In some cases, the warranty will not cover installation costs at all. Check the warranty terms when you’re shopping for new vinyl. Liners of higher quality usually cost more upfront, but their warranties are typically longer.

Conclusion “How long does a pool liner last?”

Even though you may find it expensive to replace your swimming pool liner, not doing so can be detrimental. If a vinyl liner leaks frequently, it should be replaced before it causes structural damage to the pool.

Take advantage of late summer or early spring sale prices to enjoy a full swimming season while having your pool liner replaced.
