    Why would you want to?

    • Depressurise
    • Take out valve
    • Fill with water


    Unless of course you mean how do you do a hydrostatic test, in which case;
    • Take to good dive centre / test centre
    • Pay

    I've just seen your other thread, about filling it with O2 then popping a 'few thousand PSI'.

    Dont, just dont. If you use a steel tank, the increased oxygen content in conjunction with 'a lot' of moisture means it will rust quicker than a Fiat.

    I am still interested in why you would want to do this?

    You wait till friday before posting stuff like this...

    I presume you wish to make a super soaker of sorts...?

    Use a hozelock/Killaspray doofer as a pressure chamber (the big ones with the stirrup pump style bit coming out the top) - fill that with water.

    Fill the diving air cylinder with air only, never water. Use this with a cheap reg, de-tuned to an appropriate IP (I think it's a measely 4 bar?), then use something like an LPI hose and a standard LPI nipple, or better yet some posh conectors with a shutoff on the male end. CAREFULLY drill and tap a hole into the pressure chamber of the sprayer, or better yet re-use an existing one. Make sure the nipple is adequately secured, otherwise it will become a missile if it breaks loose...

    Fill the sprayer with water, then attach the hose from the regulator. Open the cylinder valave to pressurise until the pressure relief valve lifts on the killaspray, then shut off. Now go soak someone.

    In fact, that sounds so easy, I might just go and fettle one up!

    Pretty sure that's length of the spanner, not the opening!

    Though this one might help you with any large nuts you need to move...
