What Exactly is a Pool Liner?
A pool liner is a protective layer that’s installed inside a swimming pool to provide a smooth and watertight surface. It’s typically made of vinyl or similar materials that are resistant to water, chemicals, and UV rays. The liner will be custom designed to fit the specific shape and dimensions of the pool.
The primary purpose of a pool liner is to prevent water leakage and maintain the integrity of the pool structure, acting as a barrier between the pool’s structure and the water. It’s also a visually appealing finish to the pool, enhancing its overall appearance.
How Long Will a Pool Liner Last?
Most inground pool liners have a lifespan of 10 to 15 years. Like any other part of your swimming pool, the liner will last longer if you maintain it properly and carefully monitor the chemical balance of your pool water.
What are Some Signs That I Need to Replace It?
Determining whether you need a new pool liner typically involves inspecting the condition of the liner. Here are some signs that your pool liner has reached the end of its lifespan:
- Visible damage –Look for any visible signs of damage, such as tears, rips, cracks, or punctures. These can occur due to the age of the liner, or they may be caused by sharp objects or improper pool maintenance.
- Fading or discoloration – Pool liners can fade or become discolored over time due to exposure to the UV rays of the sun, the chemicals in the pool water, or algae growth. These conditions can also cause the liner to become brittle. If the liner feels brittle or has a texture similar to parchment paper, it may be a sign of material degradation, and combined with the fading, it’s a sign that you may need to replace the liner.
- Leaks – If your pool has been losing water more rapidly then normal, there might be a leak in the liner. Carefully inspect the liner and look for any visible leaks or wet spots around the pool.
- Stains and algae growth – While fading or discoloration can lessen the aesthetic beauty of your pool, you may also notice stains from rust or algae. Not only are these stains ugly, but they can also make it more difficult to maintain water quality. Typically, these stains are permanent, and the only solution is to replace the liner.
- Wrinkles or stretching – Liners can develop wrinkles or stretch over time, especially if the liner wasn’t installed properly or if there have been significant changes in the water levels. Excessive wrinkling affects the appearance as well as the functionality of the pool and may require replacement of the liner.
- Age of the liner – Nothing lasts forever, not even your pool liner. Pool liners have a limited lifespan of 10 to 15 years, depending on the material used and the maintenance performed over those years. If your liner is reaching or has exceeded its expected lifespan, it’s time for a new liner.
How Can You Extend the Life of Your Pool Liner?
There are a few steps you can take to ensure that your liner lives to a ripe old age:
- Keep your water balanced – Keeping your water properly balanced slows down the natural deterioration of the surface of the pool liner.
- Make sure you have the right sized liner – When buying a new liner, make sure that the company you’ve selected removes the old liner and empties the pool before measuring for the new liner. This allows for more accurate measurement and can ensure that they install the right liner.
- Patch small leaks as soon as you notice them – When a liner leaks, water gets in behind it , rusting the metal structure underneath the liner and this water can damage the concrete bottom of the pool. Therefore, patch any leaks as soon as possible.
- Get a good winter cover for your pool – Covering your pool in the winter keeps debris that could damage the liner out of the pool, but also protects the liner from the UV rays of the sun.
If you’ve observed any or the signs listed here, or if you have concerns about the condition of your pool liner, it’s best to consult a professional pool company. A professional pool maintenance company can replace your liner if it needs it, or repair it so you can enjoy the old liner and put that expense off for another season or two.
