All plumbing is not metric, but some of it is. It's not all imperial, but some of it is. I think the white stuff is imperial (but sometimes given to the nearest metric conversion) and the grey stuff is metric. Or that's how it seems to be here in Spain. I've got to the stage where I take a mangled piece of plastic tubing into my local fonteria, and a white-haired lady, the same age as my mum, goes into a storeroom and comes out a minute later with the exact replacement part I need. In my last place I made friends with the old boy who ran the small, but perfectly formed, fereteria, and he helped me a lot. Well, I showed him the picture and he sold the thing to me.
Going to screwfix is even worse now since they took away catalogues and only have the iPads and if you don’t know the correct wording for what you need you can’t find it. Farce
