The pool may be tilted if the pool bottom is not completely level, smooth and wrinkle free. The pool liner must be completely stretched and there must be no wrinkles on the bottom before the filling process begins. When filling the pool with water, it is recommended to fill the pool with only about 1 cm of water and to completely level the bottom with bare feet. If the bottom of the pool is perfectly level, but the pool is still tilted, then the problem is with the position on which the pool is placed. Find a different, level, firm and non-tilted spot.
