Most of Killarney Vale was built between the 1970s and 1980s. The original water supply pipes
— galvanised steel in older homes, copper in slightly newer ones — are now
40–50 years old and past their expected lifespan.
Galvanised steel corrodes from inside, narrows bore, then fails
#1 cause
Aged copper joints solder joints crack under pressure over time
Very common
Heat stress outdoor pipes in Central Coast summer heat
Seasonal
High mains pressure splits aged fittings at weak points
Intermittent
