Running a CCTV camera down a drain to find the fault

Match the Symptom to the Service

  • Water backing up inside Gurgling floorwastes, a toilet that rises when the shower runs: that is the sewer side, and blocked sewer is the page.
  • Water backing up outside A soggy lawn, a pit overflowing in the rain: that is blocked drains territory, or stormwater if it only happens when it pours.
  • You want answers, not guesses A camera run through the pipe settles any dispute about what is down there: CCTV drain inspections.
  • The pipe itself is the problem Recurring roots, cracked joints, a line that blocks every winter: pipe relining or drainage repair and installation fixes the pipe, not just the symptom.

Undecided which page is yours? The diagnosis section further down sorts the four apart, and the camera settles the rest.

Roots, Clay and a Century of Head Start in Wahroonga

The gardens came first, then the pipes paid for them

The Federation, Arts and Crafts and Colonial Revival homes went up on generous garden blocks alongside the street trees that now tower over them. Those mature trees have spent decades finding every joint in the original vitrified clay drainage beneath the lawns.

Roots enter, joints crack, silt follows

A line that drained perfectly in 1930 becomes a recurring blockage in 2026. The canopy here is too dense and the clay runs too old for a quick clear to ever be the end of the story.

That is why every drainage job in this suburb starts with the question of what the pipe itself is doing, not just what is inside it today.

The Wahroonga Ridge and Where the Water Wants to Go

The elevation does the suburb no favours underground

At about 202 metres, this is one of the higher addresses in Sydney, and the ground drops into sandstone gullies on nearly every side. Rain that lands here does not linger; it travels, and it takes the fastest route the terrain allows.

Clear lines make the slope a blessing

Root-cracked or silted lines make the same slope turn a blocked pit into a torrent crossing a lawn within minutes of a downpour starting. The blocks facing the gullies cop it hardest.

Steep fall means fast flows that scour the inside of old pipes and undermine the bedding beneath them. A line that survived forty gentle winters can suddenly start settling, cracking and leaking its own foundations away. Any drainage plan for a sloping block here has to respect the water's speed, not just its volume.

What Each Service Covers, and When You'd Call It

Drainage repair and installation

New lines built properly, or old runs rebuilt where patching has run its course. You'd call it for a renovation adding a bathroom, a new dwelling connection, or a run that has failed one time too many. Around Iloura Avenue we regularly replace original runs at the end of a very long life.

Blocked drains

The most frequent drainage callout in this suburb, because the established canopy never stops pushing roots into the older lines. A gully trap filling when the washing machine empties, a smell arriving with the rain: all point here. We clear the line properly, then say honestly whether the pipe behind it needs more.

Blocked sewer

When the main sewer line blocks, the whole house knows. Multiple fixtures gurgle, the lowest drain starts to fill, and the risk shifts from inconvenience to hygiene fast. This page keeps sewer diagnosis, clearing and repair separate from general blockages, because a sewer fault has its own rules and its own urgency.

Stormwater

Roof and surface water belongs outside and away, and this service makes it happen. Every April the deciduous street trees shed into gutters and grilles, and the next solid rain hunts out every packed one. We clear, repair and install runs, pits and connections sized to what the ridge actually delivers.

CCTV drain inspections

The camera is the honest broker of drainage work. It shows the pipe's true condition, finds the root plate, measures the crack, and turns "we think it's roots" into footage you can watch yourself. Pre-purchase inspections, recurring blockages, dispute settling, or working out whether relining is even possible: all start with the camera.

Pipe relining

A resin liner threaded through the existing pipe and cured in place leaves you with a brand-new line inside the old one, without any excavation. In a suburb where the gardens are often as precious as the houses, relining is frequently the difference between a drain repair and a landscaping bill.

How We Diagnose What's Underground

Step one: the camera

Every serious drainage job starts with a CCTV drain inspection, because digging blind in a suburb of mature gardens and shale soil is how small jobs become large ones. The camera shows the blockage, the pipe material, the crack or the root plate, and exactly where it sits.

Step two: the clear

With the picture in hand, we clear the line with the right tool: high-pressure water jetting for grease, silt and most root masses, cutting attachments for the stubborn plates. Clearing comes before repair decisions because you cannot assess a pipe you cannot see through.

Step three: the verdict

The footage decides what happens next. A sound pipe that simply had a blockage needs nothing further. A cracked or root-riddled run gets the honest choice between relining and replacement, and we lay out both options with fixed prices so the decision is yours, not ours.

Signs by Property Type: Houses, Units and Older Homes

Federation and interwar houses

The original clay runs are the standing risk. Recurring blockages, a soggy patch that never dries near the line's path, or gurgling that arrives with heavy rain all suggest the joints have failed and roots are coming back no matter how often the line is cleared. These homes are the heartland of pipe relining.

Postwar brick houses

The 1960s to 1980s stock often runs earlier terracotta or early PVC drainage, better than clay but still ageing. Houses here carry generous roof and paved areas, and original stormwater pipes laid decades ago were never sized for the downpours that now hit the ridge. Overflowing pits in a storm are the tell.

Units and apartments near the station

Strata drainage is shared drainage: one blocked boundary trap affects multiple dwellings, and body corporate politics mean the diagnosis needs to be documented properly the first time. Camera footage that can be shown at a strata meeting is worth its weight in concrete.

What the Trees, Soil and Slope Mean Together

Three local forces act on every underground line here at once

The canopy pushes roots in from above. The shale and rock soil gives roots nowhere else to go but along the pipe trenches, the softest, wettest corridors in the ground. And the ridge slope drives fast water through whatever the roots have narrowed.

The local pattern follows from it

A drain that blocks in autumn, clears fine, blocks again in the summer storms, and by the third recurrence is clearly a pipe problem rather than a content problem. That pattern is why this hub keeps pointing at diagnosis before clearing, and repair before repeat callouts.

Fixing the pipe once costs less over the years than clearing it forever. The same combination also explains why prevention looks different here than in flatter, younger suburbs: a maintenance plumbing visit that checks gutters, grilles and downpipes before April's leaf-fall does more for a stormwater line than any emergency clear after it fails.

A camera inspection, a clear, a reline and a full replacement are four very different jobs, and each is quoted on what your pipe actually needs, never on a worst-case assumption.

Where the Drainage Work Sits Beside the Rest

Drainage overlaps the other silos at the edges

A blocked sewer flooding a bathroom floor right now becomes an emergency plumbing matter, and the emergency hub carries the make-safe steps while this silo carries the repair. A burst pipe under a driveway is burst pipes work.

The neighbouring trades have their own hubs

A hot water unit leaking from the base is hot water repair territory, and the hot water hub covers that side of the trade. For everything above ground, the plumbing hub is the directory, and the contact page has every way to reach us.

We also cover the neighbouring streets: Turramurra, Warrawee, Hornsby, Normanhurst and Waitara each have their own local page, and the same canopy-and-clay pattern follows the ridge through all of them.

Good questions, straight answers

Drainage Questions Wahroonga Locals Bring Us

Do you clear tree roots out of old clay drains?

Yes, we cut the roots, flush the line and then put the camera through it to see whether the pipe needs patching, relining or replacing, so the blockage does not simply return next season.

How do I know if the blockage is the sewer or the stormwater side?

Sewer trouble shows as gurgling fixtures, slow toilets and smells, while stormwater trouble appears as water pooling outside, and a camera survey settles the question definitively before any digging starts.

Can you reline a drain instead of digging up the garden?

In most cases yes, because relining threads a resin liner through the existing run and cures it in place, which suits gardens full of mature established trees that nobody wants excavated.

What does a CCTV drain inspection involve?

We feed a camera along the pipe, record what we find and show you the footage, so the diagnosis and the fixed price rest on evidence rather than guesswork.

Do you handle stormwater problems on steep, gully-facing blocks?

Yes, sloping blocks here shed runoff hard, and old lines that coped for decades can back up in a single downpour, so we clear, repair or reline the run as the camera footage dictates.

Is drainage work covered by your warranty?

Every job we complete is covered by our Lifetime Labour Warranty, and the fixed written price is provided before any work begins with a $0 call out fee.

How fast can you get here for a drain backing up?

We work these streets every day, so the van is often minutes away, and you get an honest arrival window during the call rather than a vague promise.

Will you quote before starting drainage work?

Yes, the full fixed price goes in writing before a tool comes off the van, and if the number does not work for you the call out costs you nothing.
