Question

Should the gauge pressure remain the same when pressurised but gas supply turned off. Both my stage regs are loosing pressure - if gas supply turned off then the pressure reduces slightly - after an hour they will move 100bar. Is this normal, regs are MK25 scubapros with G250 second stages. I am assuming that this is an indication that they need servicing as they do not hold pressure when de-pressurised.

Thanks all

In my experience, could be a leak around the swivel on the gauge.

Have a listen for it leaking or pressure regs and pop it in the bath

gauge pressure

Did try that, also swapped gauges around- they all seem to depressurise-even on a brand new mk11. One seems worse than the other but no lease at swivel.

Thought internal "o"ring might be knackered.

Mine dont seem to leak here with button or small contents gauge and a reg. Remain pressurised literally from one week to the next in the shed. Mk25 second stage here too on one.

They shouldn't leak, and while its that slow it isn't a problem at the minute... but may be an indication of something slowly failing, so best to find out what it it.

If you can't see any bubbles when you put it in the bath (or wherever), try it with a different SPG, with a different 2nd stage, etc, to try to narrow down to the bit that's leaking. Alternatively just take it apart and put it back together, checking the o-rings as you do so.

i always have my stage reg precharged but switched off !! ive never noticed a drop in pressure !

pressurise the whole system and then stuck it in a trough of water. This shouls show you were it's leaking from.
