Been using this JBJ Regulator with bubble counter on a 5lb CO2 tank for 1.5 weeks now. Decided to double check for leaks tonight, since I'm going away. Low and behold I found a leak
using soapy water on a joint I may have overlooked last time. I think the pictures speak for themselves. There's a nice big soap bubble where the leak is burping out. For those of you with the JBJ Regulator, I see a little bit of green stuff (almost like a filling material) where that joint goes into the metal. There is a small break in the green stuff where the leak is. Then again, I looked on the underside of this joint -- no green stuff there either, but also no leak. What's the green stuff and what to do about the leak? Apply some aquarium silicone? I'm going away for two weeks so no time to return it -- is this something I should temporarily fix and is a deal breaker to return? I don't think it can be tightened.
FYI the leak occurs with the bubble counter on or off. I am getting a steady and consistent bubble count. My left guage has been around 800psi, once at 850psi. Again, new tank but it's cold this time of year. Right gauge closest to the leak has been at the 5th hash mark on the gauge, whatever that is (25psi?) Thought this is suppose to be higher. (See pic)
As an aside, turned the lights on four hours ago, ph on Milwaukee read 6.8. Now, four hours later, it reads 6.9 and pH still running. Is this normal? Are the plants just gobbling up the CO2 fast? I run a Reactor 1000, checked for leaks there. None. Steady bubbles going into reactor.
Any thoughts appreciated gang! See attached pics:
