The pool may be tilted if the pool bottom is not completely level, smooth and free of wrinkles. The pool liner must be fully stretched before starting the filling process and there must be no wrinkles on the bottom. When filling the pool with water, we recommend filling the pool with only about 1 cm of water and completely leveling the bottom with your bare feet. If the pool bottom is perfectly level but the pool is still tilted, then the problem is in the location where the pool is located. Find another flat, solid and non-tilted place.
