Why use a P-Valve QD?

[Akimbo]

I don’t understand the advantage of a quick disconnect (QD) on a P-Valve that does not have an integral shutoff over connecting the hose directly to the condom catheter. Less residual volume in the condom when disconnecting seams like an advantage. Is it just that a QD requires less force (and risk) to disconnect?

I have only used condom catheters "open circuit" on a freediving wetsuit so the tube is only partially full of mostly salt water when disconnected. Yeah yeah, I know the peeing in a wetsuit lie… it gives me a rash.

I use Qds with shutoff on both sides. With 6 inches of tubing on the diver side of the break, I can easily get the QD outside my undergarments without any risk of exposure, allowing me to connect/disconnect in public without worrying about offending bystanders.

Got a part number? Are they plastic or metal? The ones I have seen sold with P-Valves don't have shutoffs.

I like the QDs because they "click" to tell you they are firmly seated. I used a barbed connector between the She-P and the norprene hose for a while, but it would occasionally disconnect without me knowing it, and the results were . . . unpleasant.

I won't use a quick disconnect on a p-valve. If it quick disconnected while I'm on a dive, I would pee on myself. That sucks!

There's a recent thread with all the part numbers: http://www.scubaboard.com/forums/exposure-suits/320857-p-valve-plumbing-size.html

I don't think a quick disconnect is really that much more like to disconnect on a dive than a traditional barb.

I use one because I dive in Florida, where it's hot as blue blazes during the summer. The last thing I want to do is be finicking around with anything once I've got those undergarments on. Once they go on, I am in "get to the water as fast as humanly possible to avoid filling this drysuit with sweat" mode. I can put the QD on the cath when I'm not sweating to death, and click it into place in a second, saving me time.

I keep a spare traditional barb in my toolbox because if you lose the QD piece, you are screwed. spares spares spares

Here's my part list:

I use a quick disconnect: I have a short (2-3") piece of norprene hose with a barb connector on one end which goes into the cath. The other end of this short hose has a male QD connector without shout-off valve. That way I can still "go" without removing the hose or cath, and without having to connect.

I made the short hose long enough that I can easily get to it and connect without flashing people around me, and short enough to "stay covered" when I'm walking around in shorts. I usually "carry up" for convenience, but just in case ...

I have a female QD *with* shutoff valve on the P-valve side. That way, when I disconnect that long hose is not leaking "fluids" into my suit ... I have a Halcyon P-valve that I can screw down to close so I'm not "leaking" all over from there either when I'm on the boat or at the gear-up area on land.

Henrik, Is there any functional advantage to the 2" short hose compared to connecting directly to the cath with a male QD barb connector? I'm thinking the short hose is just for modesty reasons?
