The BOV from Divematics, holds a reasonable negative test.. It wount hold overnight but no discernable gas loss after 30 minutes

That'll be the o-rings then. [1]

Incidentally, the milling out done to seat the o-rings into the spinee central barrel on the DM is very difficult (as Skipbreather said), is well executed and is no doubt reflected in its price. Negative tests are quite precious to some CCR divers. Shame the V4tec BOV jeopordises that.

[1] now I understand what all the 'OC to CCR side is open when closed' stuff was all about a few months back.

BTW, Mark - sorry to hear that you have had this hassle, again. 1 second neg, thats rubbish.

Cheers
Paul
