Decided to drain (pump out) my 20×30 in-ground pool because a)there was a 2 ft tear in the liner to repair and b) there was a lot of debris to remove from the deep end. After repairing the tear and cleaning-up, time to refill. But wrinkles developed in the bottom and the stretch in the side wall opened the tear again. Any advice on refilling a pool to avoid wrinkles and not stress the patched area?
