vinyl pool linerIt’s a question every pool owner has to ask at some point in their pool’s lifetime: Is it time to replace my pool liner? Vinyl is the most commonly used pool lining materials, and they are susceptible to damage. Over time, a liner will begin to show wear, which can be caused by:
  • Weather
  • Pool chemicals
  • Average wear and tear
Fortunately, minor liner issues can often be repaired quickly and at a low cost. But it’s not always easy to determine when your liner is in need of a repair or a complete replacement. A general rule of thumb: When a liner needs constant repairs, shows excessive wear, or is the cause of persistent leaks, it will likely need to be replaced. Here are four common pool liner issues to watch for:
  1. Cracks, Tears and Separation
Vinyl liners are made of durable and flexible plastic that, with age, begins to lose elasticity. Older liners are more brittle and susceptible to cracking, tears and separation. These flaws are often the cause of water loss, as a hole in the liner can result in an inch or more drop in water overnight. If your pool is losing water, you should inspect the liner for cracks, tears, or separation. Fortunately, these flaws are often remedied with a patch, especially if they’re caught early. Yet, in some cases, damage may be too significant for a minor repair, as large cracks and tears often require replacement.
  1. Rust Stains, Mold, or Algae Damage and Fading
Today’s pool liners are built to resist fading, stains, and mold, but over the years – with exposure to beaming sunlight and chemicals – the liner may begin to fade and show wear. For instance, chlorine may cause a bleaching effect, which results in fading. Additionally, a disordered liner may be the sign of something more problematic. A leak around a fixture, for example, may result in rust, and black algae can cause difficult-to-remove stains. In some cases the problem may be remedied with a deep cleaning, yet persistent coloration issues are common with older liners and generally signal it’s time for replacement.
  1. Bubbling, Wrinkles and Sagging
On the floor of a vinyl-lined pool, the lining may begin to wrinkle or bubble. These flaws can be caused by a number of problems, including water beneath the liner and an unbalanced mix of pool chlorine. Wrinkles and bubbles can become difficult to reverse and may require replacement. Additionally, the liner may sag around the track and along the walls. This is a common problem, especially when opening your pool for the season. Often, sagging can be repaired and the liner can be tightened back into the track. But if the liner is left sagging for extended periods, it will begin to overstretch, and in these cases, the liner will lose shape and thickness.
  1. Continual Leaking, Water Loss
Tears and cracks in a vinyl pool liner are a common cause of water loss. If you suspect your pool is leaking, you should first check the pool lining. Yet, continual leaking through the liner can cause irreparable damage. For instance, water that seeps through a cracked liner can wash away the sand base under the pool, which can lead to sinkholes at the floor. Other cracks or seams may be difficult to locate. If your liner continually loses water, it will likely need to be replaced. Leisure Contracting provides comprehensive pool maintenance, installation, and repair services in Maryland.
