Nobody does a first stage repair underwater.
Maybe if they are in a submarine underwater. The myths go on and on.
Why Piston vs. Diaphragm???

What, you don't bring your #6 spanner, hex wrenches, IP gauge, and bench vise down with you? STROKE!
Daniel, *2nd* stage "repairs" (clearing debris by opening the diaphragm cover) are not unheard of underwater, but there's not much you can do with a 1st stage without tools.
I'm not sure how much underwater repair I would get into, but I don't think that anyone is suggesting replacing the HP seat while underwater.
I have seen people switch second stages underwater. I believe this is what "they" are referring to. I guess that the same would go for switching first stages onto another bottle.
Yes, in both cases the first stage will flood, regardless of design. I've heard that pistons will tolerate a flooded first stage better.

Are you guys telling me that you did not get your torque wrench environmentally sealed?

awap:Are you guys telling me that you did not get your torque wrench environmentally sealed?
My torque wrench is made of solid marine grade stainless steel. Isn't everyone's?
Anyhow, I use Apeks DS4s for first stages on my doubles and deco/stage regs because they are environmentally sealed (I dive year round in New England) and parts are easy to get ahold of. My single tank regulator is a ScubaPro MK25. I have never had a problem with it in cold water, though I know several people who have. My cold water single tank dives are usually shallow enough that I don't concern myself much with regulator failures, otherwise I would probably switch to DS4s. The Mk25 routes and breathes really sweet.

daniel f aleman:
Be specific, then. What can you repair in a first stage underwater without bringing tools down with you?
How does piston vs diaphragm mitigate changing or clearing a first stage? It makes no difference to the first stage WHICH you use.
However, anyone who thinks this is needed in an openwater environment is clearly the "clown" in this case.

Damn, that's twice today that I've been called a clownNetDoc:
Seriously, it's pretty extreme and the average diver shouldn't have to do this. I think it's more a way to resolve long deco's and malfunctioning regs. I don't think it ever shows up a first choice.
