    Because of the valve issue, I now have a folding metric allen wrench set in my save-a-dive kit.

    Here are some pics. Apologies if some are blurry. I'm not sure what kind of corrosion I should be looking for. Are the valve parts stainless steel or aluminum?

    The tech told me that I need to pull the whole insert thing out after every dive or two, rinse the insides (and the insert itself) with freshwater, air dry, and then put it back together.

    I believe it is chrome plated brass. In those photos, you are missing the DIN oring.

    Hey Mark...

    That tool kit only gets larger...never smaller...to a point where I have a nice collection of empty...''no longer big enough'' tool boxes...each one somewhat larger than the last...

    Best...

    One o'ring appears to be missing and this is the cause for the leak!!

    Lots of advice and I agree with some of it. :D

    Lots of variances on the insert. However, I have found a hand held impact driver to be invaluable to getting stuck inserts out.

    It uses a 3/8" square drive so you can use any hex that uses the same drive. Don't use any penetrating oil, just keep a left hand torque on the drive and hit the end with a hammer. I've never lost a valve or an insert this way.

    Once out, I use this on the tank to clean out the scuz.

    Like @markmud, I do lube the insert, but not the o-ring.

    Not too bad in my opinion.
    Definitely fixable. Once out, clean them well. I've used vinegar before with good results.I like the tool @The Chairman suggested.

    I've also seen what @boulderjohn mentions. They've just never seen one.

    C...

    Tool's nice...but be mindful of the fact you're impacting against soft brass...on a relatively thin walled DIN valve...an ''L'' shaped Allen key...with the levering end extended with a ''cheater'' tube...places no impacting force on the head of the valve...

    Brushing out the threads is a good idea but a stiff bristled tooth brush would be just as effective...the twisted steel end on that rotary brush will chew right through the soft brass at the rear of the valve...

    This isn't NASCAR...

    Best...
