The difference between sound and water waves is that sound waves are longitudinal, ie the local displacement of the medium is parallel to the wave travel direction, while in water it is perpendicular. The wave thus does not really have a 'height', it would just fill the entire tube, and there wouldn't really be a way to miss it.
