Question about removing first stage underwater

[Big Bubbles]

If you had to to save your life would it really matter if it was damaged. Anyway you just have it cleaned.

...... Seems to me that it's a good idea to purge as you open the pillar valve if you were to do this.

Excellent point. When I put the reg back on my valve later on that day and turned on the air, of course I took a breath to make sure it was working. I'll never do that again! I got a lung full of water.....

I was just reading the thread in which SeaJay reported on his DIR-F class, and I read this:



Wouldn't water get trapped in the connection between the valve and first stage? Or no? If so, wouldn't that cause problems with the regulator? I was under the impression that water in the first stage was a Bad Thing (tm). I guess I'm wrong?

I've replaced K valve o-rings (other people's, although someone did it for me once) underwater a few times. It's not good for a reg, but nothing an annual service won't remedy.

I sure wouldn't do it without good reason.

I imagine Andrew wasn't too concerned about fresh water. I'd rather have quarry water in a reg than pool water.

I'll chime in and say "ONLY" as a last resort. It can be done quite easily, but I don't want to put my regs through that kind of hell.

you'll fry your SPG or any air-integrated computer if you shoot water down the HP hose. Fix = $$$

Willer, are you sure about that? I honestly have no idea myself, but you'd think that the equipment companies should have a reasonable expectation of moisture in a reg at some point, even if it's from inside a poorly maintained tank...

I've rarely rebuilt a customer's reg that didn't have some degree of evidence that water had been present at one time or another.

FWIW, I wouldn't bother doing it on back gas. Why would you?

However, if a deco reg failed it may be worth doing.

 

[Amphibious]

Popeye - Vapor and small droplets that condense int he reg don't seem to bother it much, but a blast of liquid can damage the delicate parts of an air integrated comp.

(or so "they" tell me, I'm no expert)

Cracking a valve too fast after swapping out regs underwater can send a slug of water into your reg, sometimes tweaking parts.
Be careful or it may not be a simple case of servicing.
