This is a bit premature, but I'm confident.
Tested up to 120 PSI or thereabouts, but a nagging small gasket leak kept reducing the pressure. Picture shows pressure at 7 bar, or about 105 PSI. No other signs of trouble, and I'll re-do the test next week when I've made some more gaskets.
I'd like to run the boiler at 80 PSI.
Thought you'd like to see pictures.
