Hi everyone, I have a bit of a problem that I need help with. A few days ago, literally a few hours before going to France on a school trip, my CO2 went off. After checking I realised that the bottle, which should have lasted for months, was empty after only two weeks. I had no choice but to leave it until today - thankfully no real problems. Anyway I went back to TGM who GAVE me a new bottle so I could check everything (Thanks guys! Once again brilliant service) and low and behold the cheap regulator/solenoid that I bought off ebay (yes, the one loads of you have got) is leaking at the joint between the solenoid and the bubble counter. My question is how do I seal this joint and make it airtight? I am trying to join two metallic pieces to each other and, short of welding, I am stuck as to how to do this. Any help would be greatly appreciated. P.S. If you have one of these systems please check all your seals carefully. CO2 is heavier than air and at relatively low concentrations is poisonous.
