Thanks for the tip.
Don't think that I will try it myself - happy to DIY pretty much
everything apart from plumbing and plastering...
I think the expansion vessel is not happy either - had some problem with
pressure dropping last year, had it re-pressurised then, but still
pressure dropping slowly, so may need replacing now.
Also a few drops under the boiler once every few weeks - nothing
serious, and no logical explanation, but I suppose it is time to have it
look into as well now.
Thanks again.
