Building watchdog blames manufacturer for leaky plumbing in Perth homes

A comprehensive investigation into the mass failure of plumbing pipes used in hundreds of new homes in Perth has laid the blame on a manufacturing fault, potentially absolving building companies of liability for the flooding issues.

On Wednesday WA’s building and plumbing watchdog announced the results of further tests into the cause of the water leaks from a particular brand of polybutylene pipe, known as Profit, made by Iplex Australia.
