the valve on the pressure/expansion unit is I think obviously the water supply and when I turn it on it still raises the pressure - rather then reducing it to a safer level. The radiator near the boiler does not have the same valves as the other radiators. This radiator is not coming on- it was last year and I havent altered the valve. I tried bleeding it but just got lots of water coming out - which i understand means it didnt need bleeding. it did lower the pressure a bit - but then I turned on the valve on the pressure gauge ad it went back up to the max high of 3.
Does anyone know why my radiator isnt coming on ?
And why the pressure is dangerously high?
