      Yeah may be iron aswell. Those old ferrous pipes looks pretty bad on the inside aswell. I’d be quite surprised if there wasn’t any plastic pipes used but I guess that’s possible.

        Interestingly the whole circuit for the building was redone a few weeks ago. There was no plastic used at any point to the mains (except for a temporary link while waiting for one of the trenches to be dug). As I said, it’s just not used here.

        It is used for parts of the outgoing flow though, but most of it is still cast iron as well. I’m not in the US, so YMMV.
