    Pee valve problems

    I took my drysuit to the lake for the first time thisweekend. I had never worked up the courage to use the pee valve last year. Justto help my ego, letís say HUGE problems this year.
    At about 5í, as the suit compressed, I started to feel apull. I thought the norprene tube was just getting caught, so I surfaced andadjusted things. I did this a couple times with no success. I decided I wouldpush it just a little but before I got to 10í a vacuum had formed and it wasnot comfortable at all. By this time I figured it was time to get out and takea look. After having to ask for help taking my tank off I was able to disconnectand release the vacuum. This brought new meaning to the phrase ďthatíll leave amarkĒ.
    So, short story shorter, what did I do or not do? What am Imissing? I sure donít want a repeat of this little episode.
    Questions, comments and jokes please.

    Ouch. I still dive wet but I never even thought about this problem. I anxiously wait for an answer as well. Wild guess, air compresses; maybe you have to make sure there is no air to form a vacuum. If no one answers by Saturday I'll ask the owner of my shop; he dives dry most the time and has no problem talking about this sort of thing.

    Wow... That gives a whole different meaning to having your buddy do a pre-dive gear check.

    I drive dry about 99% of my diving.
    would help a little to know what overboard valve you have
    Balanced / unbalanced , what brand.
    Is the tube the black crushed neoprene, or that clear tubing
    tube routing? Straight down, or do you loop it back up.

    I think it is a balanced valve. There is no bolt that I can remove for a straight shot out. It is a Pinnacle Evo II suit and the valve came with it-second hand. I am using a 1/4" norprene tube with a check valved quick connect. I ran a loop down and back up so the tube is about 15" long. I attempted to prime the tube but there was not a free flow and I didn't close the valve after. Once the vacuum formed it didn't release until I disconnected the quick connect. How would I know if it is a bad valve?

    DD, you're making me nervous. Especially since you always have that camera handy

    could be an issue with the check valved quick connect
    I don't use the quick disconnect stuff.
    I run the 1/4" straight down about 6" of tubing. eg from end of the cath to the balanced valve. or actually it's reversed. tube comes up from the balanced valve to the end of the cath.
    This way it's impossible to kink, bend etc.
    so you either have a check valved quick connect issue, or the actual pee-valve is the issue.
