Hi
I have a Worcester 24CDi RSF Combi Boiler in which the pressure drops. An engineer diagnosed and changed Expansion Vessel, Pressure Relief Valve and Automatic Air Vent but the problem still remains there. When I isolated the flow and return connections under the boiler from the whole system and topped up with 1.5 bars leaving in overnight, it is alright without dropping the pressure in cold. But after opening the valves filling the system leaving it over night, the pressure drops 1.0 bar in cold. I keep topping it up expecting to see an evidence of a leak from the joint but nothing so far. I pulled up carpets and could not find any leaks in the system as well. Is it worth putting some 'leak sealer' in anyway? Does anybody have any advice on how I could trace the issue/leak?
