We are just putting up a intex 32' x 16' ultra frame rectangular pool. The ground is level as we had this professionally done. We have followed the instructions and have the boards under each leg. As we started to fill the pool which is about 18" of water the sides are leaning inward. The ends and corners are okay. It is the middle section of the sides that are leaning inward.
Is this normal during filling procedure?
Will the sides push out as the water fills up the sides? or what do we need to do to correct the sides from leaning inward?
