Rusty Pipes? What It Means for Your Home

Why You Shouldn’t Ignore It

Rust is that four-letter word that often spells disaster for householders — especially when it comes to the hidden pipes carrying water or gas.

Rusting downpipes, gutters and roofing are obvious. But it’s the pipes inside your plumbing system that can quietly deteriorate over time, leading to costly damage if ignored.

Why Galvanised Pipes Are a Problem

Galvanised iron pipes haven’t been used in new builds for decades, but many Adelaide homes still rely on them. As they age:

• The protective zinc coating breaks down
• Rust forms on the inside of the pipe
• Sediment and corrosion gradually clog the pipework

This can restrict water flow, reduce pressure, and eventually lead to burst pipes.

Warning Signs of Rusting Pipes

The good news? Rusted mains pipes give plenty of warning. Common symptoms include:

• Brown or discoloured water when taps are first turned on
• Metallic taste in the water supply
• Lower water pressure throughout the home
• Small leaks forming on exposed pipework

While discoloured water isn’t harmful in the short term, it’s a clear sign that your pipes are deteriorating and need attention.

Quick Home Test

Not sure what type of pipes you have? A simple scratch test can help:

• Galvanised pipe: silver or dull grey under the surface
• Copper pipe: reddish-brown shine when scratched

If you discover galvanised pipes, it’s only a matter of time before rust becomes a major issue.

Why Replacement Matters

Leaving rusted pipes in place can lead to:

• Burst pipes and water damage
• Higher repair costs if failures occur suddenly
• Contaminants entering your household water supply

Replacing old galvanised lines with modern copper or PEX piping ensures safe, reliable water and gas delivery for years to come.
