Remote regulator pressure adjustment tool and method using same

An assembly, comprising:

• a pressure regulator comprising a first housing,
• a first spring moveably disposed within said first housing, and comprising a first end and a second end;
• an adjuster cap disposed in said first housing and in physical contact with said first end of said first spring;
• a pressure regulator adjustment tool comprising a second housing formed to include a first bore extending therethrough, an adjuster piston moveably disposed within said first bore, wherein:
• said adjuster piston is attached to a rotatable adjustment knob;
• rotating said adjustment knob in a first direction causes said adjuster piston to move downwardly in said bore;
• and
• rotating said adjustment knob in a second and opposite direction causes said adjuster piston to move upwardly in said bore.

A method to adjust an output pressure of a remote pressure regulator, comprising:

• providing a remote regulator comprising a first spring to set an output pressure, a threaded adjuster cap in physical contact with a distal end of said first spring, wherein said adjuster cap is formed to include a plurality of key slots extending inwardly therein;
• attaching to said remote regulator a regulator pressure adjustment tool comprising a pressure gauge, a rotatable adjustment knob, and a moveable adjustor piston, wherein said rotatable adjustment knob is coupled to said moveable adjuster piston;
• attaching a pressurized gas input source to said tailpiece of said remote regulator;
• observing an indicated output pressure of said remote regulator using said pressure gauge;
• rotating said adjustment knob in a first direction to increase said indicated output pressure;
• and
• rotating said adjustment knob in a second and opposite direction to decrease said indicated output pressure.
