What matters for plumbing in Perth

  • A domestic garden bore drawing from the shallow superficial aquifer to irrigate under 2,000 square metres does not need a water licence, but it is still bound by the roster and the winter switch off. Perth groundwater often carries enough dissolved iron that it rusts on contact with air and leaves orange staining on limestone walls, render, paving and fences. Iron levels vary block by block and cannot be predicted before drilling.

  • Never put a zinc coated galvanised gutter under a COLORBOND, ZINCALUME, glazed terracotta, fibreglass or aluminium roof. Those are inert catchments and the gutter corrodes early. Piping air conditioner condensate into the gutter does the same thing.

  • About 68 per cent of WA detached houses are built of brick, and WA is the only state where more than half are, on HIA figures. Perth's solid double brick walls mean new cabling, pipe runs and heavy wall fixings usually need core drilling and chasing rather than a quick run through a stud cavity.

  • Double or cavity brick is still the normal way houses are built in WA, where the east coast mostly uses timber framed brick veneer. There is no stud cavity to fish cables or pipes through, so new power points, data cabling, relocated taps and rangehood ducting usually mean chasing into brickwork or running surface conduit. A quote priced on the assumption of a timber frame will be wrong.
