Is a check valve truly important for DIY CO2? Can it wait a few weeks or should I get it right away? I want to setup the CO2 ASAP but dont have enough money to get the check valve.
I have one but as GIS said I havent needed it yet. With a new bottle you shouldnt need one but it is when the bottles get older that I would really reccomend one. I also would NOT wait over a week to get one.
