I have a five year old Baxi Combi 105HE that's started to drip. I've taken the front off and AFAICT the water is coming from the region of the three-way valve and everything in the area of the heat exchanger is bone dry. I used to use a really good heating engineer but I don't live in their area any more so whoever I call will be a stranger and I'd like to preempt the possibility of being taken advantage of.
So.... I presume that a faulty three-way valve on a five-year-old combi is not a terminal condition and that anybody telling me to scrap it should be shown the way to the door - right?
Could anybody give me a ballpark figure for how much it ought to cost? I'm not trying to do this on the cheap - a tradesman has to make a living - but I'd like some idea of what the parts and labour ought to come to before I give anybody a call.
Thanks!
Nick
