Hi all, I have read at several places that the lelit PL41TEM (with PIDed, but should not make any difference) does have an OPV but that the pressure is set at approx 12bar and that this cannot be changed. I wanted to know if this is true, and if there is really no way of changing the OPV pressure. If impossible, how hard/expensive would it be to plug an adjustable OPV instead? I have never owned a lelit before and just seems weird that the constructor would bother plugging an non-adjustable OPV ?! thanks.

I have an interest for that machine and im wondering why you would want to adjust the opv settings? Do you think that you need more than 12bar of pressure to pull your shot? Isn't it dangerous to blow your brew head of pump if you go to high? I rarely see a coffee that should be extracted at anything higher than 10bar. Please explain.
