Ozark/Geoff: Did you get a PF wit gauge? im looking to do this mod to one of my PF's but would like a frame of reference for how much the OPV will be getting turned. You have a giotto, right?
Also, does anyone have a pic of where the valve is? I remember reading that it is adjustable, but the adjusting screw is under something, or, behind another fitting? Im hoping this explains the bitterness my shots are experiencing.. thx!
ive found plenty of info.. thanks! heres some cross referencing in case someone else needs it:
Hi, I assume your PF is same size as the Andreja's (58mm)? I want to rig one of my own. Although the Andreja is equipped with one, I suspect I am having a pressure problem so I want to test it right where it comes out... Thanks.

Hi,
Has anyone tried taking the pressure measurement from the steam wand? You may only need a VERY STRONG hose, two hose clamps and a pressure gauge. The advantage is that you could see the pressure while brewing.

Two points: - the pressure in the steam wand is going to be (at best) 1.5 bar, versus 8-13 bar in the portafilter. So you don't need a very strong hose.
- taking pressure readings from the steam wand might be interesting, but bear NO relation to the pressure you're pushing through the coffee.
The "modern" style espresso machines were designed to specifically get away from pushing steaming water through coffee. So the espresso head and steam arm have different feeds internally, they aren't all connected up together.

The QuickMill Andreja Premium and Vetrano models are quite similar, except that the Vetrano is a plumbed rotary pump machine. So yes, I'm sure my PF gauge would work with your AP. You might want to spring for a glycerin-filled gauge to eliminate potential oscillations from your vibe pump.
