Removing wrinkles from above ground expandable pool liner with hopper deep end?

Answer 1

Most wrinkles can be avoided by waiting for a warm sunny day to install and fill an expandable bottom pool. Lay the liner out in the bottom of the pool stretching it across the deep end. Align all the seams, Then place sand bags all around the bottom edges, inside the pool stretching the bottom tight and working out the wrinkles. Keeping the liner stretched tight with sand bags, hang the liner sides over the sides of the pool walls. Add a small amount of water to create a puddle in the deep end, Then at the hot-est part of the day when the water you added earlier has warmed, and the liner is at its hot-est and soft-est add water very very slowly. Pausing periodically to allow the added water to warm. The weight of the warm water will cause the warm liner to sag more and more (to stretch evenly) into the deep end, This is not a time to rush, If you fill too fast the water will pull the sides of the liner into the center, sand bags and all, instead of stretching the bottom. Leaving it badly wrinkled! If this happens pump off the water and start stretching over again. When the deep section is all full and the main pool area has an inch or too of water covering it remove the sand bags and finish filling the pool. In cold climate this process could take a few days.
