Old Homes, Old Pipes: Why Older Melbourne Properties Need Water Filtration

Melbourne’s older properties, from Victorian terraces to mid-century weatherboards, are part of what gives the city its character, but ageing plumbing behind those walls can affect water quality in ways new homes rarely experience.

Ageing Pipe Materials

Older homes may still have sections of galvanised steel or copper pipework that can corrode internally over decades, occasionally introducing sediment, discolouration, or a metallic taste into the water supply.

Lead Solder in Older Fittings

Some plumbing installed before the 1990s used lead-based solder on copper joints. While mains water itself is treated and monitored, older internal plumbing is a separate consideration worth being aware of.

Pressure and Flow Issues

Narrower, older pipe diameters combined with mineral build-up over the years can also reduce water pressure, independent of anything happening at the mains.

What Filtration Can and Can’t Fix

A whole house filter can meaningfully reduce sediment and improve taste from ageing pipework, but it does not replace deteriorating pipes. If you are noticing ongoing discolouration or pressure issues, it is worth having your plumbing itself assessed alongside considering filtration.

What This Means for Melbourne & Victorian Homes

Old Homes, Old Pipes: Why Older Melbourne Properties Need Water Filtration is particularly relevant here in Victoria, where water is drawn from a mix of protected mountain catchments (for most of Melbourne) and, in regional and peri-urban areas, from bore water, rainwater tanks, or smaller regional catchments with different treatment profiles. Melbourne’s catchment water is generally high quality by world standards, but it still undergoes chlorination before reaching your tap, and ageing infrastructure in some suburbs can affect taste, clarity, and mineral content by the time water reaches the property.

Homes on tank water or bore water in regional Victoria face an additional layer of consideration, since these sources aren’t subject to the same centralised treatment and monitoring as reticulated town supply. In both cases, understanding your specific water source — and testing it, if you’re unsure — is the first step before choosing a filtration system, rather than assuming a one-size-fits-all solution.

Verified Standards & Further Reading

For homeowners who want to verify the certification claims made in this article, we encourage you to check the primary sources directly rather than taking any supplier’s word for it (including ours):

• Search any plumbing product’s WaterMark certification status directly on the Australian Building Codes Board’s official WaterMark product database.
• Verify NSF/ANSI certified water treatment products and the specific standard they are tested against via the official NSF certified product listings.
• Read the current Australian Drinking Water Guidelines published by the National Health and Medical Research Council for the official national standards on drinking water quality.

All AquaCo filtration systems supplied and installed by Vic Water Filters carry WaterMark Licence No. 23448 and are independently tested to the relevant NSF/ANSI standards for their stated contaminant reduction claims, including PFAS/PFOA and PFOS reduction where specified on the individual product datasheet.
