I am a brand new pool owner and have developed wrinkles as a result of the liner "floatintg";water behind the liner from either ground water or a leak; when the liner settles back into place it leaves wrinkles. I am having my system checked for leaks ( and repairing if there), and looking into the ground drainage away from the pool ( and correcting). then i will have the pool compnay reset the liner to take the wrinkles out. if it happens again after all that i will just be SO mad!
