Hi Boris, The valve fits item no. 33 on this drawing here. https://www.svb24.com/en/jabsco-on-board-toilet-new-style-comfort-with-soft-close-lid.html Basically prevents water waste flowing back into the bowl. There are a good videos from Jabsco on YouTube on how to change the valve. Here: https://www.youtube.com/watch?v=uqYkXa5AWe8 Thomas
