What galvanised pipe is
Galvanised pipe is steel pipe coated in zinc. It was widely used for water supply in Melbourne homes until copper and plastic took over, and many Hampton Park homes built in the 1970s still have some, often in walls, under floors or in the line from the meter.
How to spot it
Look at the pipe near the meter, under the house or behind the laundry trough. Galvanised pipe is dull grey, threaded at the joints and attracts a magnet. Copper is reddish-brown and does not.
Why it fails
The zinc coating wears away over decades and the steel rusts from the inside. Rust narrows the bore, so pressure drops and water can run brown after the taps have been off. Eventually the pipe develops pinhole leaks or a joint fails, often inside a wall.
What to do
If you notice low pressure, discoloured water or a leak in galvanised pipe, have the line checked. Replacing it with copper or approved plastic pipe, all at once or in stages, restores pressure and removes the risk of a hidden burst.
Hampton Park soil and pipes
Hampton Park sits on heavy grey clay over sandier ground towards Lyndhurst, and that clay swells in a wet winter and shrinks and cracks in a dry summer. The older homes west of Hallam Road were mostly connected with earthenware sewer pipe in short lengths, and every joint is a place for roots to get in once the ground moves. Galvanised steel water pipe from the same era rusts from the inside, narrowing the bore and eventually leaking. On the newer estates, PVC drains are tougher, but trenches that were not compacted properly can settle and leave dips that hold grease and paper. We use a drain camera and pressure testing to see what is actually happening rather than guessing.

It is generally not a health risk, but rust can discolour water and reduce pressure.
