We have had a new radiator installed as part of redoing our hall, stairs and landing. The plumber used plastic pipes to connect it - we didn't think to specify and I guess it's easier. But now I'm unsure about the look of the pipes - they don't look obviously plastic in finish, but they are, of course, 'bendy' - so they seem somehow a bit odd, especially combined with the column radiator that we've installed. Any thoughts? Am I being mad to think about changing them?
