bobo Posted April 1, 2010 Report Share Posted April 1, 2010 Hey guys. For DIY CO2, do you need a check valve if your bottle is sitting above the tank? Or am I safe ;p Cheers Quote Link to comment Share on other sites More sharing options...
oO SKIPPY Oo Posted April 1, 2010 Report Share Posted April 1, 2010 i think your fine if the bottle is above the tank as the water can back siphon Quote Link to comment Share on other sites More sharing options...
Aquila Posted April 1, 2010 Report Share Posted April 1, 2010 You are safe from from the tank water getting into the bottle, but you are not safe if the co2 mix over-froths and siphons into the tank. Quote Link to comment Share on other sites More sharing options...
