I have a suggestion: Looking at your CO2 bottles, I see you are using silicone to seal where the tube goes thru the bottle cap. At least it looks that way. I haven't had much luck doing that. It seals for awhile, but since most of those caps are made of materials silicone doesn't adhere well to, the seal soon starts leaking. The better way to do this is to drill a hole smaller than the tube O.D. then poke/pull the tube thru the hole. That makes the hole grip the tube so tightly it seals mechanically. Better to change that now rather than after a week wondering why no CO2 gets to the water.
