Hi All
I have a 12 year-old combi boiler from IMI Range Ltd (whatever that is) and it is constantly making noise. I thought it could do with a descale, but have no idea how to administer a descaler like Fernox or Sentinel. Should this be done by a professional plumber or can I just go out and buy this and administer it myself?
Thanks
