Plumber Thornlie

Thornlie WA 6108, City of Gosnells. About 15 km south-east of the Perth CBD.

Thornlie is a large residential suburb about fifteen kilometres south-east of the Perth CBD in the City of Gosnells, with the Canning River along its northern side. It was developed in stages from the late 1950s onward, and the older sections are known for big blocks of seven to nine hundred square metres and heavy street tree cover. For a plumber that means long service runs, mature roots over ageing drainage in the north, and much newer pipework in the southern estates.

• Large blocks with long service runsSeven to nine hundred square metre blocks were normal in Thornlie, and the house often sits well back. That makes for long water and sewer runs, so a leak can be metres from where the damp appears and locating it properly saves digging up a lawn to find out.
• Fifty years of tree growth over original drainageThe leafy northern streets sit over sewer lines laid in the 1950s and 1960s. Roots in those joints are the single most common cause of the blockages we clear in Thornlie, and clearing alone does not fix a line that has opened up.
• Two very different ages of housingNorth-east Thornlie and the Forest Lakes end are decades apart. An old house may genuinely need pipework replaced; a newer one almost never does, and anyone quoting a replumb on a 1990s Thornlie home should be asked to justify it.
• Low ground along the Canning RiverThe northern boundary follows the river, and properties near it sit lower with a water table that rises through winter. Soak wells on that ground fill quickly and empty slowly, which is a drainage design problem rather than a blockage.
