Anybody know what the pressure gauge on an Ariston Combi should read? Son has just bought his first house and the boiler gauge is at 3 bar and the water constantly drips from the overflow / expansion pipe when running. Also the fill loop valve appears to be constantly open. I am guessing the gauge should read between 0.5 and 1.5 bar, but it is only a guess. Many thanks
