Odd apeks suit inflator valve - help please

students to think they can play mechanics with a spanner. Besides we
have buddy jacket's, so not much point seeing as it's different
anyway.

But the real reason .....................................

If the need does arise at what point does swapping the hose compromise
the "let's go home" protocol?

We specificly dont have the same on all the drysuits etc. because once
disconnected the only option is to go home and even if BC hose did fit
drysuit, we dont want anybody doing anything other than can the dive.

I have two working hoses, then one, then none, I might get one back,
but then again I might not.

I have two working hoses, then one, then I go home using wing or suit.

I dont waste time or effort trying to sort this stuff out. Dive is over and
I'm on the way back to the boat for an early tea and a biccie.

Once there I get out my spare and replace the defunct hose.

Always KISS

Successfully replaced the nipple last night with the one off my old drysuit which is the apex international fitting. Thanks to advice from all - I never even noticed that the nipple had grips for a spanner which is a big clue that it can be uncrewed!!

Point taken about having the same fitting for the inflator hose on my wing and my D/S - I will upgrade this shortly.

Greens have been awarded!

ok, your wing has failed. You use your wing for buoyancy. The suit doesn't have enough lift to get you up. how do you "go home". I just unplug the suit inflator and fire the wing. Actually, thinking about it, I would be just about neutral anyway, and all I'd have to do is take a deep breath and I'd be going up. Past that point the gas in the wing would be expanding and I wouldn't have to inflate anything anyway. Wineis obviously a mind-clarification fluid as I've never thought through that before. What is all that noncy, DIR shit about anyway if you dont ever need to swap the hoses about. It's all a load of shit isn't it. I'm going to regret that last bottle of wine in the morning, I can tell. Never mind.

How about tie your smb line to your weight belt...clip your reel to your harness...drop your belt on the deck and winch yourself up...

If we are talking true redundancy, then we cant assume that the wing will
work EVEN if we swap hoses. So what you gonna do now?

Got no issue with having the same hose, but in my book that's way down
the list of get-outs. I've done drills with wing & drysuit disconnected and
I DO have enough gas to go home if it goes pair shaped.

But ..............

As you've said, chances are there will be trapped air and a deep breath
should be enough to start lifting even without air in the drysuit.

It's the idea that it's a magic getout. Far better to just unplug and use
your own buoyancy or drysuit.

I would have thought i would be faster to just disconect the offending hose, why make it more complicated, i mean is their a reason to make it harder

Rational is that you may not be able to unplug, at least not that fast.

So you shutdown, purge, then unplug and have the chance to check hose.
If lucky, you can switch on again (without hose attached) and save the
gas in that cylinder.

As a protocol that makes a lot of sense. What doesnt IMO is once in this
predicament, to disconnect the only other working form of buoyancy you
have.

Far better to disconnect and just go home using either just suit or just
wing.

If the hose is damaged that wont cause a free flow on the inflator, and in the situation that the inflator is free flowing i would have thought practicing to disconect is still the best option, burst or damaged hose ok, isolate.

I agree with you about hoses, and dont folow the logic, but then i think garf was speaking through wine, never a good plan on here.

Yep, but then you have to figure out whether to unplug or isolate.

Far better to have one action that covers both, then to get it wrong,
hence the switch off/purge, unplug mantra.

Sorry i still dont agree, i think i would notice if it was freeflowing as opposed to burst, would you not be able to tell the diferance?
