Hi,
I own a 2 x 12l steel twin-set with Halcyon valves which I use in a DIR configuration including two Atomic M1 regulators.
Typically I assemble the full twin-set the day before I go diving and briefly put the regulators under pressure by opening both valves of the manifold to check for damaged o-rings and the like.
Providing there are no problems I typically close the valves again but leave the two regulators under pressure.
The twin-set when full typically has 200 bar of gas (air or nitrox) in it as shown by the SPG on the left post.
The SPG is the only device attached to a high pressure port on the left post - the other connections are a backup M1 secondary and an unattached dry-suit inflator hose.
So here is the question:
Typically when I return to the twin-set the next day the pressure on the SPG (with closed valves, but no pressure relief) shows 100-150 bar rather than the original 200.
Is this normal - is the pressure somehow slowly diffusing out of the second stage?
Just curious - according to various dive buddies there are no bubbles during a 3m bubble check - so no obvious leak.
regards,
Rory
