What it is
Galvanised steel pipe is steel coated with zinc. It was the standard water pipe in many homes built in the 1940s, 1950s and early 1960s, including much of Noble Park near the station.
Why it fails
The zinc coating wears away over decades. Once it is gone, the steel inside rusts. Rust builds up on the inner wall, narrowing the pipe, and eats into the wall itself until it splits or develops pinholes. Joints and threads, where the pipe is thinnest, usually go first.
Signs
- low pressure, especially upstairs or at the far end of the house
- brown or rusty water after taps have been off for a while
- pinhole leaks and damp patches
- a burst under the floor or in the front yard
- repairs that cause new leaks nearby
Patch or replace?
A single burst can be repaired by replacing that section. If the pipe is failing in several places, or water quality and pressure are poor, replacing the run makes more sense than chasing leaks.
Repiping
We plan a route for new copper or polyethylene pipe through the roof space or under the floor, so walls are opened as little as possible. Many homes can be repiped in stages, starting with the service pipe from the meter.
Insurance and sale
Replacing old pipe can help with insurance and makes the home more attractive to buyers.
Planning a replacement
Replacing galvanised pipe is best done in one go, with new copper or approved plastic pipe from the meter to every fixture. We plan the route to reduce wall and floor openings.
Signs to act now
Rusty water, weak pressure and pinhole leaks are signs to plan the replacement soon. We give a written quote before any work starts. Call us to inspect your pipes and discuss options.
Noble Park pipes at a glance
Most of Noble Park was built between the late 1940s and the 1970s, so original houses usually have clay sewer pipe, galvanised or early copper water pipe and gas hot water outside the laundry. Newer townhouses on subdivided blocks have PVC drains, plastic or copper water pipe and continuous-flow or heat pump hot water. We use cameras, locators, pressure tests and leak detection gear to see what is going on before anyone digs or cuts a wall.
