Hi All,
Would like some expert opinion or input from your experience.
What is the recommended OPV reading or setup for E61 grouphead machines with a double boiler & rotary pump configuration ?
Should it be 8,9 or 10 at maximum on the pressure gauge during extraction?
I also did read somewhere that pressure at e.g. 10 bar at the gauge translates to approx 9 bar at the OPV - grouphead ?
Is that right?
Thanks for your reply,
Cheers
