rexliz Posted January 3, 2007 Report Share Posted January 3, 2007 For pressurised CO2 I have a soda stream bottle (100l one), a Tools Online regulator, a solenoid and needle valve. However, I am finding that a full bottle lasts less than a week, ten hours per day, one bubble per second. I use airline from LFS - it is blueish in colour - and obviously it is not CO2 proof. Would this be leaking the CO2 at this rate? or is it likely that I have a leak elsewhere? Should I use thread tape on all the joins? Any help would be appreciated.

HandS Posted January 3, 2007 Report Share Posted January 3, 2007 At a guess, id say there is a leak somewhere else, i used standed airline when i had a sodastream sized bottle, and i was getting about a month out of it. What type of bubble counter are you using??? i found it hard to seal home made ones. HTH P.S Yes to the thread tape, even if you dont need it, it doesn't hurt Quote Link to comment Share on other sites More sharing options...
rexliz Posted January 3, 2007 Author Report Share Posted January 3, 2007 I'm not using a bubble counter - have a flipper diffuser from one of the fermentation CO2 kits - you can see the bubble rate easily on it. What size soda stream bottle did you get a month out of? Quote Link to comment Share on other sites More sharing options...
Angus Posted January 3, 2007 Report Share Posted January 3, 2007 Sorry to hijack the thread a little bit, but Hands - i'd have to disagree on the thread tape idea. I'm not a gas plumber but i deal with industrial gases at work and it's generally frowned on to use thread tape with gas plumbing in case small bits get into the line. Depends i suppose on the end use (hi-tech instruments differ from CO2 supply to aquariums) so it's up to the individual user. Recommendation is to make sure the seal is tight and leakproof using soapy bubble-laden water. hth Angus Quote Link to comment Share on other sites More sharing options...
camnbron Posted January 3, 2007 Report Share Posted January 3, 2007 If you are worried about thread tape getting into the lines just use thread paste as an alternate, you should be able to source it from the same place that you buy thread tape. But you should use some sort of sealant at least and then leak test the line Quote Link to comment Share on other sites More sharing options...
HandS Posted January 3, 2007 Report Share Posted January 3, 2007 No probs Angus, i dident know better, that is just what i was told... i haven't used a sodastream bottle, but a JBL bottle that is the same size as one of those standard (old) bottles (300 grms from memory) Ive upgraded to a 3kg bottle now 8) Quote Link to comment Share on other sites More sharing options...
rexliz Posted January 3, 2007 Author Report Share Posted January 3, 2007 I must be leaking a lot - I get less than 7 days out of the large (800gm?) bottle. I will do the thread paste/soapy water thing. Quote Link to comment Share on other sites More sharing options...
