A few questions about CO2 valves and bottles:
1 )What is the point of an on/off valve. Co2 bottles have pin valves, so why have a on/off valve.
2) If my bottle has just got a pin valve can I unscrew a full/half full bottle straight off my marker or will it piss co2 everywhere.
3) How much do I really need an anti siphon tube if I have an expansion chamber (I think mines six or seven stage)
Thanx
