Oh - you could have a problem like mine;

1: Attach little bottle to big bottle (DIN)
2: Open Little Bottle Valve
3: Open Big bottle valve (a little) supposedly pisses air out from DIN
4: Check O-Ring in DIN. OK. Try Again. No Luck. Still Hissing
5: Check Inner O-Ring in DIN. Is OK. Not that.
6: Disassemble and reassemble DIN. Still not working
7: Look at little pin. Wonder for a second, then unscrew it. Put it in the other way round.
8: Cylinder fills fine. Pin cracks open fine. DSMBi works fine now!

Strange one. Pin was assembled upside down so I spoke to AP Valves and they were great - they'd heard of a couple which had been done, and apologised!

Mark.

no, it's hit the button with a spare piece of lead you keep in the car for the purpose... whilst shouting "loud noise "

I keep a large pair of pliars in my dive bag, many uses but the main one is theyre about the right weight and size to comfortably hit the DSMB purge without injuring hands or denting things. Ive never really managed to depressurise the thing with just hands.

Months of winter diving in NDD only meant my DSMBCi wasnt used at all, dusted it off last weekend to find the valve very very tight needing a vice and effort to turn on. 3 or 4 days of open/closing and it seems a bit more loose now but the purge spring is also stuff so i guess needs grease. It worked saturday but needs more work before its as good as it was last year.

Don't be tempted to take it apart to clean it. I assume that it is the same mechanism as the 'suicide' bottle which has a special type of hard o-ring and needs a special tool to insert it. My LDS (who have their own workshop) said they tried to improvise and in the end, gave up and bought the tool.

First job I got when I started work for Rolls-Royce back in 1968 was to convert a 6000 line Fortran program written to run on a Univac 1108 to operate on an IBM 360/65. Problem was that it was written in Germany and so all the variables were German abbreviations and there was no documentation and no comments in it whatsoever. Great fun.

Have you ever had the O-ring out? I had to replace the O-ring on my wife's BCD cylinder due to damage (sand) and tried replacing it with a standard O-ring of the same size but it kept rolling when the purge button was pressed. It was after this that I discussed with my LDS and they told me that they had had the same problems. The AP supplied O-ring is a much harder material and is a real so and so to insert.

Then someone always forgets to close the cylinder valve!

Another fill .... anyone?
