Local drains
Seventy years of Sorrento homes
Sorrento was surveyed as a private subdivision in 1929, but residents only started moving in during the early 1950s, and until 1981 the area still counted as part of Marmion. Houses went up in waves from the 1950s to the 1980s, so one street can hold drains of quite different ages.
That spread matters when a drain blocks. Water Corporation's tree guide says suburbs over 20 years old are less likely to have PVC wastewater pipes, and that a hairline fracture is all a root needs to get in. An early-fifties house and a late-seventies one can block for different reasons, which is why we look before we quote.
