57.     Standards of plumbing work

(1)  Plumbing work is to comply with the Tasmanian Plumbing Code and this Act.

(2)  Despite subsection (1) , a provision of the Tasmanian Plumbing Code does not apply to plumbing work –

(a) for which a permit had been granted before the provision was adopted by the State; or

(b) if the permit authority certifies in writing that substantial progress had been made on the design of the plumbing installation before the provision was adopted by the State.

(3)  Subsection (2) does not apply to a provision of the Tasmanian Plumbing Code if the permit authority and the owner of the land in respect of which plumbing work is carried out agree that the provision applies to the plumbing work.
