Reply to comment by Riff316 in TIL: Thanks to poor internal communication at NASA, information about a spacesuit water leak wasn't properly communicated. Later, Astronaut Luca Parmitano almost drowned on a July, 2013 ISS space walk, his helmet filling with several liters of water before they could get him back inside. by OvidPerl

I assume it would depend on the amount of water. I feel like if it is enough water to fill a helmet to the point of threatening to drown, the expanding water itself would probably block up any small vent or opening in a helmet before a meaningful amount of it was evacuated. I'm not a space man though so it very well may work.
