You probably already realize that your pool’s vinyl liner won’t last forever, but you may not have considered exactly how often you’ll need to replace it. Vinyl pool liners typically come with warranties of 20-30 years, which can be misleading, because this is not the typical lifespan of an average pool liner. In most cases, you can expect inground pool liners to last between 6-12 years, and above ground pool liners to last 6-10 years.

If you spend little time on its care, your liner may need to be replaced sooner than this; and likewise, with proper care and maintenance, your liner has the potential to last for much longer. Here are a few considerations that will help you get the most life out of your vinyl pool liner:

Keep the Water Chemistry Balanced

It’s important to monitor and maintain your pool water’s pH and alkalinity levels. In addition to keeping your pool clean and safe, the chemical balance of your pool affects the lifespan of your liner. If your pool water is often acidic, it can degrade your liner more quickly. It’s also important never to add undiluted granular chemicals, like chlorine, directly into your pool because they can settle on the bottom and attack the vinyl. Instead, always dissolve the granular chemicals in a bucket of water before adding it to your pool water.

Avoid Punctures

Thicker liners are more resistant to punctures, but it’s still best to keep your pool free of objects with sharp or rigid edges that could easily puncture the liner. Clearing your pool of debris not only makes your pool cleaner, but it also removes sticks, stones, and other objects that pose a risk to your liner.

Monitor the Water Level

If your pool’s water level becomes too low, it can cause the liner to shrink, leading to tears. Monitoring the water level will also alert you to small holes or leaks in the liner, which can be easily patched before they develop into larger issues.

Cover Your Pool

It’s also a good idea to cover your pool when it’s not in use. Not only does a pool cover keep your pool free of debris that might cause punctures, but it protects your pool from excess sun exposure, which can cause the liner to fade and become brittle over time. Winterizing your pool during seasons of non-use can also help to prolong your liner’s life.

Install the Liner Right

It’s possible to replace your pool liner yourself using a vacuum or blower to suction it to the pool walls. It’s important to measure accurately and ensure the liner has no wrinkles. Proper installation also impacts the lifespan of your liner, so if you’re not comfortable performing this task, it’s best to contact a professional to replace it.
