(a) Yes. Perth Children’s Hospital utilises an automatic phosphate dosing system that was installed before the opening of the hospital and uses a potable approved liquid polyphosphate.
(b) No. This is mainly due to there being no lead pipes on other public health facilities, and as such there is no requirement for any inhibitors.
