p-valve hose routing and undergarments

[Boarderguy]

Resurrecting thread to ask a question I'm not finding an answer to.

Regarding a new Seaskin Nova suit that came with a Sitech trigon valve installed... the hose port on the valve was installed facing the rear of the pant leg.

With the stiff "corrugated" Sitech hose attached, if I want to route the hose thru an immediately adjacent access hole in my thermals (added the option with my suit/thermals order) the default port/hose direction doesn't seem ideal.

Why would Seaskin install the valve with the hose port facing the rear of the leg instead of maybe upward or at least more in the direction of where you would normally want to route the hose?

Sure, makes sense. I was scratching my head wondering of Seaskin had routed the hose toward the rear for some strange reason that escaped me. I'd hate to speculate on what bizarre routing options some might suggest

Ya the hose routing makes a loop up toward your chest and your private parts points straight up. If there is a hole for the hose then great, otherwise most one pieces have dual zippers so you can unzip it from the bottom a bit and route the hose through that way.
Also i pee while standing in shallow water all the time, not sure why it’s a problem, if run some alcohol through the hose after each day of diving then it shouldn’t have any uti concerns…

I just got my dry suit and I am struggling with the logic of touting the hose up and back down. If my boy naturally faces down why not have a shorter hose and leave him facing down vs up towards my stomach? I must be missing something. Thanks

Why not just run a shorter hose from you straight down to the p-valve? I’m new to a dry suit and don’t understand the up and then back down thought. Thanks

Because it works just fine the way boarderguy illustrated. Id rather the hose be too long than too short...

You need a gradual bend to allow for flex/movement. If you had a short downwards hose:

1. Something is going to disconnect/be yanked off when you move or twist during a dive
2. You may find your member supporting the full or partial weight of your drysuit when gearing up or getting out of your suit, until something gives. You may find this uncomfortable
3. Short direct hoses, and down-the-leg loops, can get sharp kinks. You do not want to pee into a blocked/kinked hose.
4. A longer hose with the hose clips/plugs at your waist means it's easier to discreetly plug and unplug yourself in public areas without breaking any indecent exposure laws...
5. Some of us can't fit everything in the short 12-14" distance to the valve..

Lay down in a simulation of dive trim, which way is up? And what Rohan said

Think of it like a service loop in an air hose. If it's run straight to the end point and the line is pulled by some unseen force you'll have a stressed connection and maybe a leak.

When routing up, then back down to the valve you give yourself a bit of wiggle room for the hose to move without stress on the connections. When laying flat it isn't an issue. When standing, it isn't an issue.

I used to run mine done but had a loop in the hose and never had any issue that way. It felt more natutral to me. I currently run it up and then back down simply because I do not want to put a hole in my undergarments.
