Shelly Beach's 1950s–60s fibro beach cottages were plumbed with galvanised steel and early
copper. These pipes are now 60–70 years old — well beyond their design lifespan.
The salt-laden ocean air that blows off the Pacific accelerates corrosion dramatically, eating
through fittings and pipe walls years before an equivalent inland property would fail.

First step is always shutting off the main stop valve and locating the burst. From there, the
repair method depends on pipe material, accessibility, and how extensive the damage is:
Cut-and-splice repair section cut out and replaced with copper or PEX
Accessible
pipes
Press-fit copper no-flame fast connection — ideal for wall
cavities
In-wall
repairs
PEX flexible pipe routed through wall cavities without opening up
Concealed
runs
Full repipe all
galvanised replaced with PEX or copper throughout
Whole
property
Most accessible burst repairs: 1–3 hours
on-site. In-wall bursts requiring access panels: 3–6 hours. Full repiping of
a Shelly Beach beach cottage takes 1–2 days.

PEX is often recommended over copper for Shelly Beach properties due to its resistance to
coastal corrosion.
Shelly Beach's original fibro and weatherboard beach cottages were never built for longevity
— they were holiday shacks. Their galvanised steel plumbing has now survived 60+ years of
coastal salt air, and most is well past failure point. Many homeowners are choosing this moment
to repipe the entire property with PEX rather than patch individual failures.
