The way water gets into a cylinder is if it gets emptied by any means while still submerged. If this happens then you should always get the cylinder checked at a testing station. |
Wasn't talking about a pony, was talking about a side slung cylinder for deco. Yes I agree a pony should be turned on as it will be a right ballache to try to turn it on when its strapped to your main cylinder.
I think the best bet for deco cylinders to protect the diver in case of breathing off a mix with > 21% O2 below its MOD and the cylinder from water ingress is to pressurise the 1st stage, 2nd stage and hoses then turn the cylinder off until you need it.
