According to this movie you should use Diving Helm to gain such effect. If this not work then something is wrong with Breathing Tube spells.
Also notice that the tooltip says:

Allows the wearer to breathe under water. Must be within vision range of the buoy floating in Daggercap Bay.

"If the helmet does not work, there must be something wrong with the tubes." - pretty close to real life troubleshooting. 😄

58de22c there is a visual issue with the rope and the breathe under water buff seems to reset at each second and intrerupt you when you channel the loot of crates , the npc seems fine it doesn't fall undermap.
