Thanks. I assume that re. The cover, I do not have to have BG do the flush?I.e its OK if I have another plumber do it and give me written confirmation that he has?
Hi
I have a 3.5 year old Keston Q28S combi boiler on a pressurised system that has been losing pressure for some time.
BG have finally diagnosed a split heat exchanger that they are replacing under contract.
They say that this is due to "aggressive (!) water" and that they will not cover...
