Hi
since topping up pressure on my valliant 831 ecotec plus the pressure has gone over 3 bar. This occurs even when the boiler is not in use. In order to maintain constant 1bar I have turned the water feed to the boiler. The taps have been checked, o-rings replaced in the braided filler loop that connects the taps.
The boiler was rising to 3.5bar and spilling alot of water from around the release pressure pipe although there was dripping from that pipe outside. The pressure builds up in 2 hours regardless of whether the boiler is in use. Any clues as to where the water is getting into the system please?
