CO2 BPS changing by itself

i dont understand this thread, are you saying you leave regulator at a good bps rate, then a day late the bps slows down, so you increase the regulator bps again, then it slows down again? so you are increasing the co2 flow more and more each day? doesnt make any sense.

It's difficult to keep a LOW bps unless you have a good regulator, that's why some of the expensive ones advertise they can do as low as xyz/1 bps etc... but as long as you have a average 1 bps or higher, it should not decrease by itself....
 
What the OP is describing sounds like a 'textbook example' of having the regulator set too low. he doesn't say he turns the reg. up, only the needle valve.

Due to the nature of gas, pressure builds at higher temp and decreases at lower temps. I suspect goalie has his thermostat set to cool off a bit while he's at work. He says when he comes home, it's lower output. If you turn up the working pressure on the regulator and use the needle valve to adjsut the flow, you'll see less flactuation in the actual output. assuing the regulator doesn't have -1bar and -2bar, sounds like it's set to pretty much the lowest setting available on that regulator, which would absolutely result in a visible change due to ANY fluctuation in room temp.

The other option is, it's a POS needle valve. Cheaper vavles are known to 'slip' over time and lose their adjustment setting. This seems less likely though given the setting of the regulator.
 
I will try to get a pic tomorrow or today however you want to look at it. I did turn up the operating pressure to just over the 2 bar mark which i hope takes care of the issue. Thanks for all of the help.
