What fails first in a mid-century house

Many post-war homes still run on original earthenware pipes prone to cracks, sags and collapses. A camera pinpoints the issue exactly.

Homes of this era were generally plumbed in copper with clay drainage, both laid well and both now decades past installation. Copper itself ages slowly; what fails is what joins it, and the flexible hoses added under sinks and vanities in later decades.

A failed flexi is the classic unattended flood, and it is also the cheapest thing in the house to have replaced before it happens. Worth doing on a quiet Saturday rather than meeting us on a wet one.

What living near the water does to drains

Ground close to the water holds more of it, sits lower, and moves more than ground further up. Over decades that shows up in the drainage as joints that have opened slightly, falls that have flattened, and lines that silt where they once ran clean.

Perched above the ocean, Dover Heights cops constant salt-laden wind that corrodes ageing pipework and joints. CCTV shows us where it’s failing.

None of that is an emergency by itself. It is the reason an emergency here often turns out to be the last stage of something that has been developing quietly, and why the camera run after the clear is worth more than the clear.

Steep blocks, and getting to you at night

Steep driveways, stairs down to the door, and no clear place to park all cost minutes in daylight and more after dark.

Steep streets falling toward the cliffs move stormwater fast, and blocked pits overflow in heavy rain. We clear them and keep them flowing.

It helps enormously if someone can meet the crew at the street with a light on. And if your property has a hard access point — a locked side gate, a shared drive, a set of steps that is the only way in — tell us on the phone rather than when we arrive. It changes what comes off the van and how.

When the stormwater backs up

If it is happening right now: stay out of moving water, lift what you can off the floor of the garage, and clear any grate you can reach safely from dry ground. Do not lift a surcharging pit lid — the water underneath is moving faster than it looks.

Once the rain stops, the pit that overflowed usually has a reason, and it is rarely the rain. Silt, roots or a collapsed section will do it, and the difference matters because one of those is a clean-out and the others are a repair.

What to do while the drain is backing up

Stop using water anywhere in the house. Every flush, every sink and especially the washing machine adds to whatever is already sitting in the line, and a machine mid-cycle is the single most common way a slow backup becomes a floor to mop.

Established gardens and street trees send roots into cracked clay sewer lines, a common cause of blockages here.

If there is an overflow gully outside and it is running, that is the system doing its job and keeping it out of the house. Leave it clear and let it work until we arrive.

Corrosion, and the fittings that go without warning

Dover Heights sits high on the clifftops above the Pacific (postcode 2030), an exposed, breezy suburb of family homes bordering Rose Bay, Vaucluse and Bondi. Salt air, sea winds and sloping streets take their toll on drains, and we know the local pipework well.

Salt air shortens the life of everything metal on the outside of a house: tap spindles, external copper, hot water casings and the fixings holding them up. It is slow and even rather than dramatic, which is exactly why it tends to be noticed all at once.

The emergency version is usually an external fitting letting go. Isolating at the meter stops it immediately, and the replacement should be specified for the environment rather than like-for-like.
