I've just moved into a new house and have had the central heating drained while I've worked on the pipework. I've just refilled it and am noticing a slight pressure drop - about 0.1 of a Bar overnight. It is a Worcester 35CDi combi.
I can't find any leaks on any of the pipe work I have seen. I'm worried there could be one in some inaccesible place.
Any advice on how to locate the problem. Does that Fernox leak sealer work? Should I disconnect the loop in?
