Subject: add an OPV to the Saeco/Starbucks barista?
 

since i switched to a proper machine with an OPV and a 3-way solenoid valve over a year ago, i have 3 (or 4, can't remember), Saeco/*$$ barista machines sitting around for me to play with.  i have naked unpressurized portafilters for them (had them for years, actually).  i have not formulated a plan yet to deal with temp stability and don't know when i will.  what i want to do first, since it sounds easy and feasible, is to install an OPV.  i don't care if it's tight fit or doesn't fit at al in the small space.  i'm not worried about where to drain it's discharge either.  it will be a test machine, so if i have to hang the OPV outside the machine and drain it into the sink, i'm ok with that.

so:

1) has anybody done this?  i have no ambition to be a trailblazer
2) if not, any suggestions/tips/advice?
3) which OPV from which machine should i try?

i've seen a few theads where they've been added to gaggias, but if they've been added to this family of machines, i've missed it.

I have not seen the insides of a Saeco Barista machine and do not know the space limitation.  I looked at mods some time ago and found an OPV that would seem to be adaptable to most machines.  An inline splice between pump and boiler and a return line to the tank, or any drainage spot.

The only difficulty that I see is matching tubing sizes and getting proper clamps/seals.  

McMaster-Carr seems to have most adapters and fittings, some help in this thread by Tracerbullet.  It might be a geed read before you start.
