Hi my vokera linea water pressure is rising over 2 bar when off. so i can only presume that it has to be one of two things either the stop cock valve on the right hand side of the boiler (the one with the little black lever on it) is letting by when the lever is in the normal operating position or the plate HE is leaking mains water to the CH side causing the excess pressure. the filler loop is always connected from the stop cock valve to the CH port if i disconnect this (unscrew filler loop) from the the CH return port will water flow out of the return connection or is there an non return valve in that connection so that i can unscrew it? so that i can see if the stop cock valve is letting by.
