I was wondering, during my pool sessions - learning buoyancy control etc - when at the surface with an inflated BCD, we were told the two main ways to submerge was to pull the shoulder dump valve and also to use the BCD air valve/pipe; holding it up and releasing the air.
I noticed when getting out of the poo, the BCD had water inside it from using the shoulder dump valve to submerge. I'm assuming this was where I've held it open too long, all the air has been released and the water then ran in?
Does the air inlet/release pipe/valve on the BCD have a valve to prevent water ingress? So if using this once under water, will this prevent water flowing in? It wasn't a problem but I figure this is not good practice to allow water inside the BCD, if not to maintain it but for buoyancy control?
