Ive had an issue with my CO2 Art regulator too. First 5 lb. tank only lasted a month and the bubble rate wouldnt stay constant. I suspected a leak and they agreed and recommended checking the regulator fittings, bubble counter, and in line diffuser. I did, no leaks.
I then put soapy water on the seam between the solenoid block and bubble counter block, and found the leak, bubbles from both sides. Who knows why they didnt have me check this.
Only two screws to take it apart, which I did. Put some silicone on the O ring and it still leaks. I am now waiting for their recommeneded fix. I assume theyre going to send me a new O ring. Im also going to use silicone sealant between the blocks.
Im not impressed. I have a gla unit on another tank. It works perfectly and I havent had to re adjust the bubble rate in months.
