I'm sure this topic has already been covered at some point but what does having an off/off valve for a c02 tank do? I want to do some target practice in my backyard and will need to keep tanks full for a day or two after filling but I've heard that c02 leaks from tanks and I was wondering if having an on/off valve maybe stopped this? If not what does it do?
Thanks for your help.
