Pool liners help keep water in the pool while preventing leaks. In addition, they protect your pool’s interior from physical damage while enhancing its beauty. Pool liners provide less favorable conditions for bacteria and algae to thrive.

Pool liners don’t last forever, meaning they must be replaced over time. Discussed below are five signs to replace your pool liner.

The pool liner is old

The average lifespan of vinyl pool liners depends on whether your pool is above-ground or in-ground. Above-ground pool liners can last from six to ten years. Their in-ground counterparts can last about five to nine years. With regular maintenance and cleaning, pool liners can serve you up to 20 years.

Several elements influence how long your pool liner lasts, including the vinyl’s thickness and quality, how regularly your pool is used, and the amount of sunlight the vinyl liner is exposed to. Note that vinyl pool liners that experience a lot of use are likely to age faster and have a reduced lifespan. If your pool liner is old or you’ve had it for a long time, it could be time to replace it.

Pool liner leaks

Leaks in your pool liner can result in water damage, possible structural damage to the pool, and high maintenance costs. Pool liner leaks can be caused by the following:

  • Wear and aging: Pool liners deteriorate over time because of constant use and exposure to UV rays and chemicals. This weakens them, causing leaks
  • Chemical imbalance: Poor chemical balance in your pool water can hasten the liner’s degradation, making it susceptible to leaks
  • Sharp objects: Rocks, tree roots, and other debris can damage your pool liner if you aren’t careful, causing punctures and tears that lead to leaks

Reduced pool water levels and soft or wet areas around the pool are signs of pool liner leaks. If the damage to your pool liners is extensive, a replacement is a more viable option.

Holes and tears

Your pool liner can get holes and tears for several reasons. Old liners may start tearing and have holes for no reason. Sticks, rocks, and other foreign objects in your pool can cut into your liner, creating holes and tears. This can lead to air pockets and water damage.

Holes and tears can also cause leaks, impacting your pool’s structural integrity and reducing water levels. Regular pool liner inspections can help you catch these issues on time. While tiny holes and tears can be repaired, major damage necessitates prompt liner replacement.

Wrinkles and bumps

When correctly installed, pool liners must lie smooth against your pool’s floor and walls. Bumps and wrinkles on your pool liner could be an indication that its structural integrity is deteriorating. If your pool liner is wrinkled:

  • It can trap dirt and debris against the liner’s folds
  • Snagging of the folds during pool cleaning can result in holes
  • It weakens and can create tripping hazards

If your pool liner starts having bumps and wrinkles, it could be time for a replacement.

Discoloration or stains

Over time, pool liners can get bleached by the sun, losing color. Foreign objects and dirt in your pool can cause liner discoloration and staining. The stains can be difficult to get rid of. If your pool liner is stained or discolored, it may be time to get a new one.
