alpha combi boiler cb 24?

p.s. you should set system pressure to about 1 bar on the gauge

you need to top up system pressure from the mains using the filling loop (usualy a silver flexypipe with 2 black valves) under or close to the boiler, however if the system has been in a while the pressure should not really be dropping, you may have a slow leak somewhere, I would top it up but if it goes down again call a corgi/safegas reg gas installer/plumber
