water in bcd.

maybe it's 'cause i dick around with my buoyancy too much - trying
to get it perfect - but i was struck by amount of water which
accumulates in my bcd after a days diving (which is only two dives).
i was struck with the thought that it is potentially dangerous that
the lifting capacity of the bladder gets smaller and smaller as the
dive(s) progress? is it natural for a lot of water to end up in your
bcd?

i hadn't been diving for a few months hence my absence (even if it
is mostly lurking) from this group but i'm surprised at the level of
cross posting from rec.scuba. last time i was here nearly all the
threads were worth following from a scuba interest point of view.
now the uk.rec.scuba threads seem to be easily outnumbered by the
loony political stuff from the US.

It normally happens if you're trying hard to empty it but not making sure
the dump you are using is right at the top so the water path is actually
inwards. I used to get it a lot and developed the habit of always leaning
towards the bottom dump and pulling it while kitting up just to remove
any left from the last dive but over the years there seems to be less
and less.

Sadly so. When we have a lot of crosspost threads running it just
seems to reduce the amount of 'real' traffic so the group gets even
worse. Certainly the kind of exchanges that go on in rec.funnyfarm
demonstrate why we need uk.rec.scuba if we want to talk about diving.

You will get water in the BC during a dive. You will get more in if you are
underweighted and holding the dump valves open to wring the last bit of air
out of it. The pull dumps seem to let in more than the vent on the inflator
hose. It doesn't really affect your buoyancy during the dive, and if you are
weighted properly, it shouldn't be enough to cause a problem on the surface.

The important point here is the relative density. It might carry a lot of
weight of water, but as that is the same density as the surrounding water,
it does not make you sink.

Hello all - new to the group, mostly lurking
Anyway....
If you do get water in your BCD is it sufficient to drain it out after the
dive or should you be more thorough with cleaning it?

I tend to drain the BC and then half fill with clean water, shake it about
and then let a bit out of each dump valve. This way you won't get salt or
sand/silt deposits drying in your valves and stopping them working. Every 6
months, I give it a good rinse out with diluted Milton fluid (more often if
I've been doing a lot of quarry diving).

Grief no it's just sea water (or quarry water).

If it was so nasty that you needed to wash it out you shouldn't
go dumping yourself in it. The things we wash away carefully
are from humans so clean your mouthpieces and mask with
more care.

counterlung goop is another matter.

If it's salt water (or swimming pool water) you should certainly flush
it out with clean water. If you've only been in fresh water it's OK just
to drain it out.

There are a couple of inland sites that you actually should consider boiling
water sterilization after diving there.

Killing all the cross posts will fix that.

not that I know how but could some one write a script that removes
uk.rec.scuba from the send to list
and just resend the same message with something like " I agree" added to the
end. Each time a new crosspost arrives
uk.rec.scuba gets it once and every body else just loses uk.rec.scuba in the
reply group.

just a suggestion
