Last week, having bled my radiators, I repressurized my Biasi Prisma Combi Boiler 24SE. At first, not remembering how to do it, I fiddled with the two red valves under the boiler (one on the left and one on the right) and fully opened them.
I've just noticed that the bar is reading 2.6. Is there a simple way to adjust this or should I get a plumber in?
