    Default Refilling PCP's.

    Hiya

    I always mean to ask some this question, but what with old age and poverty I keep forgetting...

    I fill my PCP pretty slowly - takes about a minute...

    Now when I close off the scuba tank's valve and release the pipes pressure via the bleed screw:

    Is it best to crank open the bleed valve quickly - so as to close the PCP's filling valve asap? Hand working the bleeder gets cold blast doing this.

    Or

    Should one be gently and bleeeeeeeeeeeed the excess air out slowly?

    Or doesn't it really matter at all?

    Hi Avion,

    It is best to fill the rifle slowly for two reasons

    1 - better control of the fill preventing an overfill and

    2 - filling slowly prevents a build up of heat and gives a more accurate fill, if the temperature rises then you can get a false reading on the gauge and the actual pressure in the rifle falls as the air cools.

    In terms of bleeding the air from the pipe the speed of this is not an issue.

    I realise that this may be a little off the subject, but I would like to know about the storage of the PCP cylinder.

    Currently I discharge the cylinder completely whenever I need to store my rifle, is this correct or neccessary?

    How long can you, or should you, maintain a stored cyclinder? Basically what is good care of the PCP cylinder, not the big iron lung.

    no...wrong move!!
    never empty your cylinder...it will make it more prone to rust and condensation inside.
    Scuba cylinders are never stored empty and if you take an empty cylinder to a dive shop they will often not fill it and insist that it be opened and checked for rust.

    Ideally fill from a good scuba cylinder that gets checked once a year and is filled by a reputable source.
    Avoid pumps if possible, or be very carful to drain the filter and clean it often.
    Once every 3 to 5 years you should check the inside of the PCP cylinder to check for rust, pitting, corrosion etc.
    This is on steel PCP cylinders as on AA rifles etc.
    On removeable alu cylinders as on the Steyr etc this is not necessary but every 5 years the cylinder can be sent back to the dealer for a check.
