You risk siphoning your tank if you fully submerge. I think the instructions also state to not do this. Since my doser is under the floor I can't press the button to see if it can pump past the blockage/skinned over end of the tube so I just clean it out quick. I imagine it still pushes past it but I'd rather be safe.
why would you siphon, thought the rollers continuously press on the tube.
It was my understanding (and the reason I went with the Profilux) that the Profilux won't back siphon, but other dosing pumps may if the tube is submergerd. Still, I wouldn't risk it.
