BCD inflator button stuck

[String]

Im amazed a stuck valve and hose disconnections werent taught in training - i assumed most/all agencies did this. Certainly here its a must-demonstrate skill and you cant be certified until proven you can do it. Most BCs out there dump and fill at much the same speed so a stuck inflation valve the system is to hold open a dump somewhere whilst disconnecting the hose.

Its fairly easy to get crud into a valve and have it jam so its pretty vital to know how to deal with it quickly.

Again, on a drysuit its a thing we trained for a lot even to the point of someone deliberately holding inflate down on a diver with a spare weight belt over him to make him positively buoyant then releaseing the weight. Diver then had to demonstrate manual disconnection of the hose AND dump air before hitting the surface of the 4m pool. Thats a club variation on a theme but ive seen various others do the same.

My one regular buddy has a dry suit inflator that seems to stick on 50% of his dives and no amount of cleaning or spraying seems to stop it. He is not VERY fast as disconnecting and continuing the dive

I would not recommend this method of training personally, the risk of P.O.I.S. does not come close to the potential benefit in my opinion.

We used to train free ascents, in the military we conducted this training in a 50' training tower. Eventually we determined (after multiple injuries and at least one death I know of personally) that it was the diving equivelent of hitting your thumb with a hammer prior to an upcoming carpentry project. (I have a better analogy but this is a family board so...)


Good skills to practice but consider your method of motivation and re-enforcement...

Has he tried changing out the valve? Bob can probally score you a good deal if you ask...

Dive Safe!!!

I also find it very strange you were not triained to disconnect your lpi in case of it sticking. It is an essential thing to teach and learn as you have just found out. I would be having a word with your instructor or checking your manuals to see if it is something that is being missed out or a gap in knowledge, or just simle neglicence. Missing out this type of skill is a pretty serious issue. If you had nothing to hols onto you were in big trouble if you had not managed to figure out to disconnect your lpi hose. Glad you are safe, but you should ask a couple of questions off your instructor. This stuff is basic for padi training, you can't advance until you learn an important skill such as this.

In the PADI system you're required to perform this skill in the second pool session either under water or at the surface. Chances are pretty good that if an instructor just makes you do it once without driving home the importance of learning it that you'll do it and forget about it.

. PADI divers practice this skill during the open water training program (as other agencies, I am sure).
Best of luck,

Do they ? not on my course !!!!!!!!

in fact we did not even realize that the BCDs had a quick realise dump untill after about 10 dives with my buddy !!

I would be asking why it isn't being shown and practiced. Have been shown it and practiced it so i know what i am doing and ma cmfortable with it. If you can't disconnect an lpi hose and haven't been shown what to do you could be at risk of seriuos injury if a stuch hose pops you to the surface because you don't know what to do. Popping to the surface from 12/18 metres isn't a good thing in my book. mY instructor has made sure we know this skill and the possible consequences of failing to accomplish it. It is also in the padi book that comes with your crew pack. Page 117.

Cant believe no one showed you the dumps on the jackets. Should be a part of your predive safety check. So you and your buddy know all the ways of dumping air from each others jackets in case of problems. Another question i would ask of my instructor.
