Picture below. It's pretty bad. It rusted when hot water dripped onto it from above. And the people who condemned it didn't do new installations. Back to my original question please.
Help! My trusty old boiler GC No 4107717) has been condemned because the gas pipe inlet (GC no 364388 Manufacturer's Part no 110143) has surface rust. The part is obsolete. Does anyone know if I could get a used replacement for a qualified gas engineer to fit?
