Well, I think you did just ask.Crawl79:Curiosity does kill the cat. I'm a warm water diver and never paid much mind to PV topics but tonight I was bored and thought I'd read this post. Now Im curious how this works but not enough to ask. Maybe one day I will learn but I think I would rather learn from my own trial and error.
A pee valve is a small round device that is installed into the thigh of a dry suit (link) that allows the flow of urine to be moved from the diver out into the water. The diver wears an external catheter (link), and a tube (link) runs from the open end of the cath down to the valve (the smart diver will not have a bunch of pluming hardware between the two).
