I've found a good local gas engineer. I am going to have a new boiler because so many spares for our old one are obsolete - I've had a good look on the web. The new one should see us out with a bit of luck.
British gas engineer has condemned and turned off my boiler - as sight glass not got seals - was cemented on by previous BG engineers for many years. Any idea where I can get a new one please - Ideal Mexico Super 3 cf 80 sight glass assembly 079334. if I can get one I will get a gas safe fitter...
