wet reg??

[redacted]

Although I think that more refers to WOB than whether it stays dry, actually mine does. Being a skeptic I spent part of a dive trying mine (T2) in every conceivable position I could, head down, doing slow 360 rolls inverted, swimming on my back, laid flat out on my back (got some comments later from my buddy), left side, right side, quick jerks of my head, slowly rotating my head/neck around (like doing a Valsalva) and I never had any water enter my mouth - little vertigo on the rolls however.

I did it when my mouth was dry so would've noticed it - plus I was trying to make it leak so would've been aware if it had. But it didn't.

And many high quality regs will perform just like that. It is not until you remain in a problem position (exhaust valve pointed toward the surface) long enough for the very small amount of water that enters each time you exhale to accumulate enough to enter the mouthpiece.

check dive results as promised ...

I used to have a wet reg only when inverted and now I have a wet reg only when I'm under water ... less so when hovering @ < 45-degree angle and almost none when perfectly vertical, so as long as I don't have to move, change positions, or otherwise perform an action I'm fine, right? This started as soon as I hit the water for my first dive (5.23). Alas, the sea did not agree w/ my plans to swap mouthpieces and the interval was spent hanging onto the boat. Same thing second dive. Afterward, I took reg + cylinder to a pool, placed cylinder on bottom & rolled around it on all 3 axis - wet all the time. I removed gear from pool, removed SeaCure from reg & attached original SP mouthpiece; it leaked less, but still leaked when moving and leaked like a faucet when inverted.

EDIT: Today(5.24) I took my rig to a diff SP dealer & the tech removed the 2nd stage, removed the SP mouthpiece, covered the hose hole & sucked in - flawless. He then disassembled it & determined that the purge valve(?? blue silicone piece other than diaphragm) wasn't completely back on. Apparently, you can put it on so it looks on and stays in place, but if you don't pull the nipple from the other side it won't lock in to the notch. He then checked the diaphragm (you can really stretch the h3ll outa those before they tear) and it's golden. He reassembled the reg & re-placed my SeaCure on it. Back to the pool - this time w/ reg + cylinder + BCD + mask - and now I'm just a little wet when inverted or rolling around. I balanced on my head & if I push the reg in against my mouth and exhale really hard, I breathe dry until I stop pushing in on the reg - got 4 or 5 breaths. No idea what would have caused it before I jacked up the purge valve, so I guess the answer is hit the gym and start doing lip-ups ...

Thanks again for all the input,

I'm not sure if I understand some of what you wrote, but I gather that it was in fact the exhaust valve leaking. That's a pretty common thing, something any halfway competent tech should catch right away.

It was either the exhaust valve or just my loose grip on the mouthpiece. The consensus seems to be the valve so I'll agree.

Today a charter ganked my seat, so I donned full gear & walked in off the hotel beach. I spent 20 min @ 15' and it worked flawlessly. The only interesting part was avoiding the waverunners overhead ... next time I'll use a biggger flag.

Quick update: G250V worked flawlessly across 3 dives on the Vandenberg in serious current. So a 'real dive' confirms it was likely the exhaust valve. Thx again for all the input.

Cheers,
