    P-Valve Placement

    Dear all,

    I wondered if I could source some information/suggestions/opinions from you all regarding the location of p-valves on drysuits.

    I have seen them positioned in varying locations and wondered why, are there benefits to these locations, or problems in others?

    I have seen them in the crotch area (I try not to stare), the thigh and the calf...

    Without wishing to be too graphic, I assumed that perhaps the shorter the distance your pee has to travel from tip (speaking from a male perspective here) to water the better. I also wondered whether, for a calf placement, wouldn't this mean you'd have a fair bit of hosing (careful now chaps) running down your leg before it reached the valve... would this require a bit more force to push the pee out of the tube?

    The crotch location just looks like it would be in the way (crotch strap on harness etc), although would have the shortest hose routing internally... the thigh placement, not sure, could it get snagged on stuff, or cause rubbing on your leg, or just look more obvious when standing in a group and you decide to wee down your own leg! The calf location presumably would mean you'd have to move a bit more in the water to open the valve?

    I do not yet have a drysuit and have not had the pleasure of using a pee valve but this is something I would wish to know about before purchasing one etc.

    Any/all information/thoughts/suggestions/opinions welcomed...

    Thanks in advance,

    Rob
    Regards

    Rob,

    Fitted on inner thigh with the most direct path, of course this is all dependent on which side you "dress",

      Have it a bit towards the front then it won't catch when you walk
      I have nothing to do with BSAC any more apart from being a muggle member. So anything I write on here is likely to be complete bollocks. Hooray!

        ... and high enough you can easily reach it if you closed it and forgotten to open it before getting in (I have the H balance valve and leave it open)

          And so you can reach it if the 1-way valve folds over and pisses water in.

            the other reason they are called a pee valve I guess

              Direct is not a problem. 'Not kinked' is. What you don't want is soft tubing.
              Once you have that you just want convenient to work the screw. I have always put it on the thigh halfway between front and between.

                Hi all,

                Thanks for all of the replies so far...

                So, already in this thread there have been a couple of differences in placement, primarily thigh/calf - I'm interested in knowing what was thought through in those choices... e.g.. why thigh over calf, and why calf over thigh?

                Thanks again for further info
                Regards

                Rob

                  Nappy is better. And, as my mate says, you can also take a dump in a nappy.

                    Always "my mate" when you don't want say something

                    In any case, I'll wait until I'm older for that experience!

                      Personally I have developed an enlarged bladder - I put this down to years of drinking and not wanting to "break the seal" :-)

                      It was actually Jack Ingle who first told me he took a dump in his nappy. Since then my mate has sworn by it!

                        Just be sure not to flood your suit, no matter what the emergency!! Or sit down to take your gear off when back on board for that matter!!
                        If my post doesnt have a typo, then I have probably been hacked!

                          Nigel - do you really mean that you have a pee-valve on the back of your leg below the knee? Or did you mean your thigh?

                              I think it will be a while before I am convinced to poop in a nappy... but thanks for the suggestion and the mental image... especially the "sitting down" comment above.. lol

                              So.. any real reasons to consider thigh over calf or calf over thigh? Was it just what had been suggested by others at the time?

                              Thigh I guess is less tubing internally... calf would be a little more... (I'm expecting all the gags here regarding "depends on your size" etc)

                              Perhaps less likely to rub if on calf rather than thigh as that part of your leg is typically thinner...

                              Thigh would be presumably easier to reach than calf, e.g. not having to bend your leg up whilst in water...

                              Anyone else got anything to add?

                              Thanks again
