Wrinkles in a Vinyl Liner
Unfortunately many vinyl pools have wrinkles. Having a low alkalinity in your pool is corrosive and can cause wrinkling of the liner or the vinyl can pucker in certain corrosive water conditions. Keeping your water in balance is critical to the longevity of the liner.
Wrinkles look bad, however some may not realize they also form a weak spot in the liner, and a spot that is at risk of being snagged by pool cleaners. Numerous wrinkles will also trap dirt against the folds, which can help bacteria and algae grow.
Once wrinkles have been under the weight of water for any length of time, they become hard, if not impossible to fully remove.
