What the Ridge Does to the Plumbing

Water runs downhill, and everything on the block follows it

The suburb sits on a ridge at around 102 metres, so on every sloping block the stormwater and waste head for the lowest corner of the lot. When the falls are wrong, water sits at the yard grates well past the storm.

The supply pipes are often as old as the houses

Much of the suburb went up between the 1950s and the 1970s, and plenty of mid-century brick-veneer and fibro homes still run on the galvanised supply lines they were built with. Those pipes corrode from the inside, so the first sign is usually a drop in pressure at the tap rather than a visible leak.

Roots come in from the ridge edge

Where blocks back onto the bushland toward New Lambton Heights along Currawong Road, plus mature gardens in the older streets, roots work their way into the joints of the old clay and earthenware drains. Census figures put 81.9 per cent of dwellings here as detached houses, so there is a lot of garden for those roots to grow through.

The Work We Do Up Here

Each of these services gets called for a reason that has everything to do with the suburb's age and slope:

Emergency plumbing

When a corroded galvanised line splits or storm run-off races down a steep street into a yard

Blocked drain clearing

Where ridge-edge roots have worked into clay joints, finished with a camera check

Hot water repairs and swaps

For the 1950s to 1970s homes still running tired units

Gas fitting

When a reno on a mid-century brick-veneer house brings in a new cooktop or heater

If a drain keeps blocking after clearing, a CCTV drain inspection shows whether cracked joints on the slope need pipe relining rather than another clear.

Common Questions Up on the Hill

Do tree roots cause most blocked drains in Cardiff Heights?

They cause plenty of them. Bushland backing the blocks along Currawong Road and established gardens push roots into clay and earthenware joints under mid-century homes. Once the jetter has the line open, the camera footage shows whether the joints can be relined or the section has to be dug up.

Can you replace a hot water unit in an older Cardiff Heights home?

Yes. Many of the suburb's houses went up between the 1950s and the 1970s, so plenty run original or second-generation units that are long overdue for retirement. We quote the swap up front, do the changeover, and a temporary tank can go in while the new system is ordered.
