As a breakaway from Tino's post on the Rebreather Accidents thread and with the onset of the dark winter months, I've been musing on how easy it would be to do my own servicing.

As far as I can see, there are four key elements to the unit (from a servicing point of view):

- The head, handset, HUD and tempstik. I'm not touching those - they can go back to APD. Whether it is worth having them serviced in the absence of problems is another question
- The loop. As far as I can see, that's a matter of general cleaning and cleaning/replacement of o-rings as necessary. I'm comfortable with that
- The regulators (two first stages, ADV, AutoAir and BOV). I assume that, with the right tools, the service manuals from APD (and the internet for the Paragon), and an element of care and attention, I could do this. Is it worth it though? I only got my OC regs serviced every 5 years or so - do I need to get these serviced any more often?
- O2 cleaning the cylinders. Is it still possible to get qualified to do this and get VIP stickers in the UK? I'm sure it used to be, but can't find any reference to anyone doing it now

I hope some of you can help, particularly with the O2 cleaning question. My favoured dive shop has closed and I now have a very long drive to get them done by someone I trust.

Many thanks in advance,
