Air Venturi All good things must come to an End? LOL

Oh, ok. Degassed to lower the Pressure. Yes. So Confusing.
For the record I have no idea what your first post is conveying either. It is very confusing. For example, what do you mean by adjusting the "Valve screw"? And when lowering a reg setting there needs to be zero pressure, not "put the pressure lower like it was before". And now you have air escaping from where exactly, where is the Valve screw?
