Hi hoping someone can help me - I ran out of oil - needed to bleed my boiler - did so with allen key but accidentally dropped the allen key and the bleed screw and it cant be recovered. Can I use any kind of a screw to fit it or does it need to be a riello part? I'm hoping to do this as economically as possible as I just had to fill the tank with oil.
you can get them on ebay, just need to know the size, if you can get a screw to fit the bleed valve for now that ok as long as the dreads are not damage by useing a different screw.
