Possibly, I did the test a few times and the bubbles would appear before the detector went off each time. I still trust using a liquid over an electric one for finding a small leak.

​@ldsYeah I get that, I'm just saying there was a covering that prevented the gas from escaping hence the detector couldn't possible detect the gas because it was trapped in the bubbles, so of course the bubbles would appear first every time. I know it's been a number of months since you did the test but it would be interesting to see if you had started turning the pipe the same amount without the solution over the joint if the detector would have detected. That said if you have an unknown leak, it might be useful to probe each joint until you find the leak instead of putting on soapy water to each joint. I ran into a problem with my dryer (gas powered) where I felt there was a leak (smelled it) but had no idea where it was, and was going mad soaping up all the joints right next to the gas hookup, etc. Eventually I found out there were no leaks from any joints in the pipe, but instead due to some faulty mechanism inside the dryer that I have no idea where unless I take the whole thing apart, and at this point I might as well just replace it (it is well over 20 years old)

I had another person comment about that. I may need to do another test. Thanks

@livefootagetube Thanks for the comment, you were obviously paying close attention. I was trying to give any honest opinion of how sensitive the tester was compared to using leak fluid. Since I did it a few times, I edited out the time of loosening and waiting for the tester to sound off and cut to a tighter shot will a different camera. To show there are a lot more bubbles in the shot when the alarm goes off. I wasn't trying to be misleading in any way.

I had another viewer mention that. Trying to think if there is a way to test the "gas in the bubbles" theory.
