Nick. In Oz & especially Qld, Plumbing is extremely regulated, which is why I question DIY work.
It is a regulation that all brass must bear the letters DR.(Dezincifacation resistent) and have Australian Standards approval.
If a fixture or fitting is found without those marks -then the installation is failed & the plumber or owner if he has done it himself is fined.
