Sorry my reply has taken a while.
The snorkles without a working purge trap water
in the u bend, Divers used to this inconvenience use a blow ,suck breathing method, as the inexperienced snorkler
inhales they inhale some of the traped water.
This has led to quite a few recorded fatalities.
Not only a big gasping breath but a slow intake of water
will cause problems.
I only endorse snorkles with purge vallves for children and
novices.
