I have some sort of gas leak but cant find it- i am also surprised how quick it is. ive emptied two soda streams within minutes trying to find it. ( a single soda stream usually has enough to carbinate and dispense about 3 or 4 20 litre brews to high levels). luckily i wans't using my main 02 canister After realising the first canister had emptied quickly, I spayed leak finding oil all over the regulator and connections and the gas line but didnt show anything, so i set it up again, but within a minute the canister was empty without any sign of a leak! not sure what to do? any ideas anyone?
