We moved into a new house about 4 months ago, which has got a Baxi 105E combi boiler. It's just over 4 years old and was serviced yearly by the previous owners.
Although it seems to work fine, it leaks. Probably about 100ml a week. It's coming out of the radiator water because I have to keep opening the valve to keep the pressure up. I had the cover off and it looks like the water is coming from deep within it's bowels.
Is this the sort of thing I could have a go at fixing myself? Plumbing is not my strong point. Jen phoned up a plumber (who comes with several recommendations) who told her over the phone that we'll probably need a new boiler. I'm a bit wary of phone diagnoses that result in large expense, so I'm not sure whether to trust them or not. I would expect a boiler to last longer than 4 years.
Any advice? Thanks.
Naich.
