Hi, advice would be gratefully received!
I'm going to need to replace some 15mm copper going into a drain down fitting. As far as I can tell the draindown is screwed onto some steel barrel. I attach a pic here

There is likely to be a fair bit of water about and I need to be as quick as possible, if I can get hold of the right nut and have it with an olive ready on the new pipe it would be a quick one off one on operation. Otherwise its pipe cutting, olive removal etcAny ideas on size etc? It doesn't look like a standard nut to me
Thanks
Peter
