After the impact of the water in the bath, the lifting rod does have the possibility of moving up. In fact, the upper part of each shower has a tightening nut, which is used to adjust the height of the lifting rod. After the height is adjusted, the possibility of moving the lifting rod is controlled by tightening the nut.
