Water in BC

[RJP]

I would completely disagree with the premise. Water, being far denser than air, would be pushed out far more slowly than air.

That's exactly why it's impossible to clear a mask at depth. Oh... wait.

:d

 

[The Chairman]

Double seals on the top and a flimsy one at the bottom of the mask makes that work. Even then, many have to push on the top of the mask to allow the water to leave from the bottom. You may want to deny physics, but it's stronger than you and I.

 

[Centrals]

You have to get the water to sit on top of the valve first. Not very easy under water.

Either way, I don't think inflating the wing will force much water out, if any.

The wing only has 1 butt dump valve and I think water will sit on the valve if I am in vertical position, that shouldn't be a problem

Inflating the wing will force water out (while on land), just don't know if that works under water

By my limited physic concept:
As long as the pressure of LPI (i.e. force to pump air in)> water pressure(i.e. force to push water in),
then I should be able to inflate the bladder with air and push water out?

While inflating the wing UW may exhaust some water, it will also send you on a fast ride to the surface. While it might work in an emergency, plan on dumping the water between dives. And get your wing fixed.

1. The dump valve is NOT at the lowest point of the bc even at vertical position.
2. You might flow away as well.

Only very small amount of water will get into the bc through the dump valve or the power inflator when you release the air. What is the possibility that you keep pulling the dump valve while the bc is nearly empty?

It is NOT normal for a fully inflated wing to lose 1/5 of its content overnight.

I manually inflated the wing when I first bought it, I found it loses 1/5 to 1/4 of the air after sit overnight.
Took it to a LDS for checking and they said it was fine though maybe minor leak

I have two Oxycheq wings if you fill it with air it will stay inflated for months. I actually tried it.

Dump valve at the bottom, overpressure valve on top. You're really certain it's the former that will open first?

What OP valve at the top?
