    Air trapped in suit

    Dived yesterday, on ascent i couldnt get the air out of my suit. Valve fully opened, when lifitng arm in air forearm was like a baloon, when i lowered arm and raised shoulder it woouldnt vent.

    Im thinking possibly undersuit blocking valve?

    Sounds a bit like it. If so, just stick a bit of gaffer tape on to the undersuit under your dump valve. I've got a Northern Diver locking cuff dump on my suit as well as the autodump just in case of issues like this. Some years ago, my wife had a problem with a bit of plastic breaking off in her dump valve and jamming it. Her membrane suit has neoprene over cuffs and neckseal for added warmth but this means it is almost impossible to get at the seals to vent in an emergency. I managed to slow her ascent by grabbing on to her and dumping everything but still a scary experience. It was after that that I fitted cuff dumps to both our suits.

    She also had an issue 12 years ago with a new Waterproof undersuit. It was trapping air and it turned out to be the metalised backing of the material not being air porous when new. It was fine after it had been washed.

    Take the valve out and blow gently through it to check it's opening.

    If it's not, replace it.
    The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.

    I think it is because the suit was designed for European air and now won't work with the semi UK air. Either that or it has got blocked with great big clumps of coronavirus.

    Be surprised if pbb xtreme are stopping it, not the type of fit/material. Check the valve.

    The dump valve works as a push dump as well. If the autovent fails to dump fast enough, push the valve in and it will dump more gas

    Took valve off suit, doesnt take much effort to blow air through. Valve had some sort of sealant on it, do i need to re-apply before refitting the valve?

    you shouldn't need sealant - there should ba a rubber backing pad stuck to the suit which the valve seals against.

    For some reasion, people love to put aquasure on them too, but it shouldn't be needed.
