Two questions:
1. I only have a single gauge regulator. I read that a double gauge will help you test for leaks. How does this work?
2. Since I can't seem to find any leaks w/ suds, if I were to turn off the Co2 tank all together then check it in a day or two w/out dispensing any beer, SHOULD the single gauge regulator still read 10 psi (what I have it at right now) ? If it were dropping toward 0, does that tell me I am leaking or will that drop anyway since the tank was turned off?
Thanks
