From Vaucluse House to Today: Plumbing in a Heritage Suburb

Vaucluse is named after one of Australia’s most important heritage properties. Vaucluse House, originally a small stone house constructed by the Irish convict Sir Henry Browne Hayes, and subsequently expanded by explorer and statesman William Charles Wentworth into a large Gothic Revival residence, was the first official house museum in Australia in 1915. Most of what is now the suburb was part of the Wentworth estate by the 1830s. That colonial legacy isn’t just a tourist tale; it is a part of the character of Vaucluse, and a part of the age of some of its housing stock.

Although Vaucluse is known for its contemporary trophy houses, it also has some very old and historic properties: period mansions, sandstone houses, and houses with real stories. Owning or living in one is a privilege, but period homes come with period plumbing realities, and it’s important to know about them.

What old pipework means in practice

The homes were originally plumbed in the materials used in their day, galvanised steel supply pipe and earthenware or clay drains. Original or early pipework is frequently found within walls, under floors and out to the street, even in a beautifully renovated home. There are two problems that come from that age:

• Corrosion of galvanised supply pipe is from the inside. Rust and scale creeps up the inside of the pipe over time, causing it to become clogged, restricting water flow, hence the surprising lack of water pressure for some older homes, and then, at some point, it bursts. Failure may occur abruptly.
• Old earthenware and clay drains tend to crack at joints. The older the trees and the more movement in the ground, the more joints open up letting in tree roots, which leads to recurring blockages in the system.

Heritage rules and sympathetic work

Vaucluse is home to several heritage listed sites, with many properties sitting within conservation considerations across the Woollahra and Waverley council areas. Plumbing isn’t just a technical issue, it must fit into the original fabric of a heritage or period home. The installation of new pipework, replacement of a hot water system or drain repairs in a heritage property require care, which can include sympathetic work with the building, preservation of period features, and awareness of what can and cannot be done.

That’s where state-of-the-art methods really come in handy. If an old drain has cracked and roots have been able to infiltrate, pipe relining can be used to provide a new pipe within the old one without disturbing a heritage garden, while sealing the cracks and preventing roots from entering the pipe. Acoustic and thermal detection locate the concealed leak without breaking the period walls in the area where a leak is suspected. The objective is to rectify the plumbing problem while conserving the home’s character.

When old pipework becomes an emergency

Aged plumbing tends to fail suddenly. A century old, unnoticed and corroding galvanised pipe may suddenly break down, or an old drain may collapse or clog. A quick, thoughtful response is all the more critical in a home with irreplaceable features and finishes from the period it was built, especially since the goal is to prevent the water from harming the very fabric that makes the home so special.

Just like with any water problem: shut off the water at the main and contact a licensed plumber that knows about older homes. Because the Eastern Suburbs are full of period and heritage properties, the team behind our emergency plumber serving Vaucluse and nearby Rose Bay works in them on a regular basis, and is always dealing with old pipework without causing damage to the property.

The bottom line

Vaucluse’s history goes back a long way; from Wentworth’s vast estate to the heritage homes that remain, the story is embedded in the plumbing of older homes. If you have a period home here, it is worth being aware of the health of your hidden pipework before it makes a decision for you, and it is worth employing a plumber who will work sympathetically with the building and not against it. Old houses will reward a little foresight, and they are better cared for today with careful, modern methods than with costly repairs.
