Hi all,
I have a 50 y/o Brasilia Cappuccino single group espresso machine and the safety valve on the boiler popped a couple of days ago.
Fair enough, it's 50 years old.
But there are no markings on the safety valve as to what BAR it was set to. What do you recommend for a replacement?

Current Brasilia HX use 1.8bar.

Since it's a heat exchanger, they usually run about 1.25bar and given the boiler age, ≈1.5bar, maybe 1.75

It's likely BSP thread
