[QUOTE="SPECIAL LOCATION, post: 505798, member: 250"] You say the boiler has only been serviced 4 times in 10 years.... What about draining and/or flushing of the heating itself? Have you had the heating water flushed out and refilled including fresh inhibitor fluid put in? If not there is the possibly of all sorts of gunk, cr4p and debris building up around the system introducing potential for corrosion etc.. How old is the pipework? Copper or plastic? Does the heating pipework pre-date the boiler? and if so, was it previously supplied from an open vented header tank? i.e. do you have the potential for some older solder joints to have deteriorated over time with the higher pressure from the current boiler? (I have seen joints that have been working fine for years burst open when a combi-boiler was added.) I've have seen bog-standard hot/water copper pipes corrode leaving pin-hole leaks.. [/QUOTE]
