I have just set up my JBL Proflora u402 system. The system comes with a 500g disposible co2 canister. I screwed the regulaot on to the bottle as per the instructions. Unfortunatly the canister seemed to still be hissing even when the regulator was screwed on tightly. The system has been running over night and this morning the pressure regulator on the left has dropped from 50 bar to 0. Their still seems to be bubbles going in. Does this mean my canister was faulty and maybe all the co2 has leaked? When the regulator is screwed on should the hissing stop?
