Anybody have any experience with a tap-rite regulator guage sticking? I have the tank in the keezer and noticed that when I thumped the guage, the pressure needle moved considerably. It's hard to adjust correct pressure when I have to do this all the time. Do you think that condensation could be affecting it? Is it better to locate the tank outside the refrigeration compartment? What about those secondary regulators, would they solve my problems?
