removing pool liner wrinkls?

Answer 1

If the wrinkles are in the floor, you have to remove them with one inch or less of water in the pool, otherwise the weight/pressure is too great. If the wrinkles are in the wall part, you have to remove them gradually as the pool fills, which means adjusting the fit of the vinyl sheet to the supporting walls. It's a tedious process, but with patience, once it's done, it's done for good - until you empty and refill the pool. Hint - the warmer the water, the easier it will be to work the wrinkles out, because the vinyl will be more flexible.
