What a water filter installation costs in Melbourne
Melbourne's protected-catchment water is soft and well regarded, so filtration here is bought to polish the taste, remove chlorine and catch sediment rather than to deal with hardness or scale, and an under-sink cartridge system is the common, affordable job. The city's deep, competitive plumbing market keeps a standard install keenly priced.
In the many Victorian and Edwardian period homes, the under-sink cabinetry can be tight or awkwardly built, so fitting the unit and running the connection neatly takes a little more care than in a modern kitchen. Otherwise the soft local water means there is rarely a need for the whole-house conditioning systems that the hard-water cities fit, so most Melbourne jobs stay at the simpler end.
