Has anyone out there had water leakage into there second stage while breathing ? If so, how bad, do you know what caused it, any info would be helpful.
And yes, I am currently working with Atomic about this, just want to know if this is a common issue or not. It has happen to both my wife's & mine in the last year.
Both are regs are 2 years old. thx
 
Have you had them serviced?
All regulators will let some water in. Also, due to case geometry, some second stages are better at scavenging water that's present inside. But, I've found Atomics to breathe pretty dry.
 
Have you had them serviced?
Happing now as they are a 2 yr service interval. But we had issues on a recent trip w/ both regs. Kind odd to happen to both.
 
I have two ST1's and have never had an issue of any kind with them
 
Test; remove the hose, inhale slightly, does it hold that vacuum? If no, 1. look carefully at the mouth piece, 2. Look carefully at the exhaust diaphragm, 3. Remove the front cover and check for proper seating of the main diaphragm, 4. Have the AFC diaphragm checked.

if yes, its something else.

Did you have any unusual diving positions, like looking straight up a lot? Most regulators will breathe dry in standard trim because any water will pool up at the bottom and exit when you exhaust. If you're on your back the water will happily flow down your mouthpiece. I find the more you dive the more attuned you become about these kinds of things.
When you do lexvil's intake test make sure you block the lp supply port with your fingertip.

Strangely on a 2 week trip, the first week was fine in all positions, but towards the last few days on 2nd week is when it started leaking in, at first when I was inverted or close to inverted, then just horizontal.

From where did you remove the hose? Dot you have the comfort swivel on it?

im assuming that even if you have the swivel on the primary you don’t on the safe second.

bottom line is if it holds the vacuume it isn’t the reg and more likely something in the way you’re diving it.
