Hi, Just got my first drysuit and had a Trigon Pee valve installed. I have not yet tried it, but I am trying to wrap my head around the mechanics. My question is basically about disconnecting the catheter from the hose after the dive. Assuming that I have used the system on the dive, is there still pee in the tube between the disconnected end and the valve? If so, when I disconnect from the hose does the pee in the tube drain out the valve or does it need pressure to exit the valve? If the pee stays in the hose, should I have a shutoff valve or check valve in the system to keep the pee from draining out the hose into the suit. Sorry if these are stupid questions, but I would rather ask some potentially stupid questions than get covered with a bunch of pee.... Thanks
