When Every Drain in the House Stops at Once
One slow sink is a fixture problem. A sewer blockage announces itself everywhere at once, and the sooner it is diagnosed, the smaller the repair tends to be. Call (02) 9072 0520 and talk to a licensed plumber who clears sewer lines every week.
Why Sewer Lines Fail Faster on This Side of the Plateau
- Bush-edge sewer runs Houses backing onto the Berowra Valley reserve sit at the bottom of long falls, so their sewer lines collect runoff and fine roots from every garden above them along the street.
- Shale and rock ground The soil here is shale over rock, which shifts with moisture and snaps rigid clay pipes at their joints rather than flexing with them the way sandy soils do.
- Autumn leaf load Heavy canopy dumps leaves into gully grates and overflow points for weeks each autumn, and that debris settles in the sewer where it snags the first root that finds a joint gap.
Sewer Services We Provide
Sewer work is a specialist corner of drainage: the line is shared, buried deep and regulated, so every job starts with seeing inside the pipe and ends with proof it flows. These are the fixes we reach for when the whole system stalls.
Camera diagnosis first
A waterproof camera is pushed along the sewer from an access point, showing whether the blockage is roots, a collapsed joint or a sagging run, so the repair targets the actual fault instead of a guess. On bush-edge blocks this step usually pays for itself.
Root cutting and high-pressure jetting
Fine roots that have threaded through a clay joint are cut back flush with the pipe wall, then the line is jetted to strip debris off the walls, restoring full bore. Most sewers on the leafier streets are flowing again within a single visit.
Pipe relining over excavation
Where the camera shows cracked or rooted joints that will keep inviting roots back, a resin liner is cured inside the old pipe, sealing every gap and adding decades of life without trenching through gardens, driveways or that established canopy you are protecting.
Sewer excavation and renewal
A section that has collapsed or sagged beyond relining is dug out by hand where access is tight, replaced in modern PVC with the correct fall, and the surface is reinstated. We only ever open the failed length, never the whole run.
Gully, vent and overflow repairs
A sewer needs somewhere to overflow when it surcharges, and a broken gully grate or blocked vent makes that happen inside the house instead. We rebuild gullies, clear vents and set overflows so any future backup shows itself outdoors, where it belongs.
What Sewer Trouble Looks Like Around Here
The brick homes built through the 1940s to 1960s, the second wave of housing after the Federation streets, often carry sewer lines that have been patched rather than renewed, and those patched runs are where repeat blockages gather.
Families here run big loads of washing and long showers, so a sewer that is quietly narrowing shows itself quickly. If the lowest fixtures gurgle first, treat it as the sewer.
Gully overflowing after ordinary rain
A gully that surcharges in light rain usually means the sewer, not the stormwater, is struggling, because household water has nowhere else to go. It is one of the clearest early warnings a line gives, and it is always worth a camera look.
The lowest toilet gurgles when the washer drains
When air displaced by water draining elsewhere bubbles up through the lowest pan, the choke sits downstream in the shared line. Clearing the fixture will achieve nothing, so the sewer itself needs tracing and clearing before the backup reaches the bathroom floor.
Repeat blockages every few months
A sewer that needs clearing twice a year has a structural cause, almost always fine roots regrowing through a cracked clay joint, and each clear without a repair buys only a few months. A relined patch or renewed section ends the cycle for good.
Why Clearing It Properly Matters
A blocked sewer is not a patience test, it is a live health and property risk that gets more expensive every week it is left. Acting early costs less and keeps the repair small.
- Sewage in living areas A surcharging sewer eventually overflows through the lowest gully, shower or floor waste, and contaminated water across tiles or carpet means more than a plumbing bill to sort out.
- Roots widen every gap A fine root that finds a hairline crack today becomes a root mass that splits the pipe within a season, turning a jetting job into an excavation if the line is left alone.
- A fixed cause ends the cycle Clearing the choke and repairing the joint it came through means the line holds for years, not months, and you stop budgeting for the same call out every season.
How it works
How We Fix a Blocked Sewer, Step by Step
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Diagnose, clear and prove it
The sewer is camera-inspected to find the fault, roots are cut and the line jetted clean, then the camera goes through again so you can see it flowing. See CCTV drain inspections for what that involves, or pipe relining when sealing beats clearing.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why Choose Your Plumber Normanhurst
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Normanhurst works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
Where We Work Beyond the Sewer Runs
Alongside sewer work across town, our vans run daily through Thornleigh, Hornsby, Wahroonga, Pennant Hills and Waitara, where the same leafy blocks and ageing clay lines produce the same faults. The full drainage scope sits at drainage services, with blocked drains and stormwater alongside this page.

Good questions, straight answers
Questions Locals Ask About Sewer Blockages
How do I know it is the sewer and not just a drain?
When several fixtures back up together, the lowest toilet gurgles while the washing machine drains, or the outside gully overflows, the blockage sits in the shared sewer line rather than a single fixture.
Can tree roots be cleared without digging up the yard?
Yes, in most cases. Roots are cut back with a cutting head and the line is jetted clean, and where the clay joints keep admitting roots, a relined patch seals them without excavation.
What does a blocked sewer call out cost?
The call out costs nothing. Your plumber inspects the line, often with a camera, and hands you a single fixed written price for the complete fix before any work begins.
How long does a sewer blockage take to clear?
A straightforward root or debris blockage is usually cleared in a single visit, while a collapsed or badly broken section needing relining or excavation can run to a second day.
Is a sewer backup an emergency?
It is. Sewage spilling through a gully or indoor fixture carries health risks and worsens fast, so stop running water where you can and call a licensed plumber straight away.
Do older homes here have worse sewer problems?
Many do. Federation and inter-war houses were laid with earthenware clay drainage whose joints shift and crack over decades, letting fine roots in, so their sewers block far more often than modern PVC runs.
