Your Drain Usually Warns You Long Before It Fully Backs Up
Gurgling fixtures, a shower slowing each week, a gully that glugs after every wash: those early warnings are worth acting on. Call (02) 9072 0504 and a licensed plumber will tell you what it likely means. Everything we do sits one click away on the Wahroonga home page.
Gravity Works Harder on a Ridge
This patch of the Upper North Shore sits high, with land falling steeply into the bushland gullies on either side, and that shape shapes every drain beneath it.
- Water moves fast here Drainage runs on gully-facing blocks carry real velocity, and decades of fast flow scour the joints of original vitrified clay pipes until roots and silt find a way in.
- Surcharges travel downhill When a line surcharges during a summer storm on a sloping block, the overflow shows up at the lowest gully trap, often near a garage or lower terrace.
- Repairs need to respect the fall A replacement run laid without the correct grade either silts up or scours itself apart, so we reinstate the original pitch on every repair.
It is the same gravity that makes the walk up from the bushland reserves feel like a staircase, working for your drains when they're right and against them when they're not.
How it works
How We Find and Fix the Blockage
Every job starts with the cause, not the symptom: here is what we clear, inspect and repair, with the right method chosen from what the pipe actually shows us:
- 01
Root cutting and jetting
High-pressure water jets and mechanical cutters strip tree roots back off the pipe's inner wall rather than poking a hole through them, which keeps the whole line flowing smoothly for years instead of weeks on the leafy garden blocks near Sydney Adventist Hospital.
- 02
CCTV drain inspection
A waterproof camera travels the full length of the drain and pinpoints whether roots, fractured joints or a sagging run caused the blockage, so the repair targets the actual fault rather than guessing from above the ground. See our full CCTV drain inspections service.
- 03
Pipe relining
Cracked earthenware joints under the older homes can be relined from inside the existing pipe, creating a smooth new sleeve that seals out roots without excavating the established gardens and mature trees those Federation-era properties around here are known for. Details on pipe relining.
- 04
Stormwater clearing
Surcharging gully traps and overflowing roofwater points get traced back to undersized or back-graded stormwater lines, which we regrade, upsize or extend so intense summer downpours rolling off the ridge stay in the pipes instead of across the garage floor. More on stormwater.
- 05
Excavation and replacement
When a clay run has collapsed beyond relining, we excavate the failed section, replace it with modern PVC joined to the sound original pipe, and reinstate the lawn or paving properly, with the whole mess contained and cleared right away.
Four Seasons of Pressure on the Same Pipes
The calendar around here loads the drains differently depending on the month, and knowing the pattern helps you catch trouble early.
- Autumn Leaf-fall from the deciduous street trees settles into gutters, strip drains and gully grates just before the wet season, so an outlet that cleared fine in March can surcharge by December.
- Summer Intense downpours arrive on the ridge faster than older stormwater lines can carry them away, and root-blocked sewer runs that coped in dry weather suddenly back up inside the house.
- Winter and spring Cool, damp months hide the slow signs, a gully that drains reluctantly or a sewer vent that smells after rain, which are worth a look before the next storm season.
Households on the big garden blocks who book a pre-summer clear of the stormwater lines rarely meet us in a panic later.
Common Blocked Drain Problems We Diagnose
These are the patterns that fill the diary, and each one has a cause worth finding before it becomes a bigger job:
The drain that blocks every few months
A drain that blocks every few months usually has roots regrowing through a hairline clay joint, and repeated clearing without a camera check treats the symptom while the crack underneath quietly widens toward a full collapse.
Everything backing up at once
When the toilet, shower and laundry sink all slow down together, the blockage sits in the shared sewer line rather than any single fixture, and that is the point where professional diagnosis beats another bottle of supermarket caustic. Sewer-specific faults are covered on our blocked sewer page.
The gully that surcharges in storms
A gully trap that surcharges during heavy rain often points to a stormwater line choked with leaf litter and silt, a common pattern on steep blocks where fast runoff carries debris straight into older, undersized pipes.
Why Clearing It Properly Matters
A blocked drain is never just an inconvenience, and the difference between a quick clear and a proper fix shows up over the following seasons:
Repeated backups cost more than one repair
Every temporary clear on a root-fractured joint buys weeks, not years, while the crack keeps opening, so the camera-first approach usually costs less across three years than three callouts.
Overflow finds the worst places
Surcharging sewage and stormwater on a sloping block heads for the lowest floor, the garage, or the neighbour's fence line, and the cleanup afterwards dwarfs the price of the pipe repair.
The garden stays the garden
Relining and targeted excavation protect the established trees and mature gardens that make these weatherboard and double-brick properties what they are, instead of trenching half the backyard for a pipe that could be renewed from inside.
How it works
Our Blocked Drain Process, Step by Step
- 01
Call and tell us
Ring (02) 9072 0504 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
Clear, verify and show you
The blockage is cleared using the method the footage supports, whether high-pressure jetting, mechanical cutting or excavation, and the line is re-verified on camera afterwards so you can see water running freely through the cleared run.
- 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 Wahroonga
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 Wahroonga 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.
Drainage is one slice of what we do, and the same crew handles everything from leak detection to full drainage repair and installation.
Where we work
Areas We Service
Our crews also work across Turramurra, Warrawee, Hornsby, Normanhurst and Waitara every week, carrying the same root-cutting and camera gear the Upper North Shore's older, tree-lined streets demand, so a nearby neighbour's blocked drain gets the very same fixed-price treatment.
Good questions, straight answers
Questions Wahroonga Householders Ask About Blocked Drains
How do you clear tree roots from a blocked drain?
We cut or jet the roots free of the pipe wall, then run a camera to confirm the line is clear and show you exactly where they were getting in.
Why do drains block so often in leafy suburbs like this one?
Mature street and garden trees push roots into ageing clay joints, and autumn leaf-fall loads the stormwater lines, so the mix of heavy canopy and original earthenware pipes keeps local drains working hard.
What does it cost to clear a blocked drain?
The call out is $0 and you receive a fixed written price before any work begins, so the figure you approve on the day is the only figure that appears on the invoice.
How do I know if it is a blocked sewer and not just a clogged toilet?
If the toilet blocks but every other fixture drains normally the problem is usually in the pan or its trap, but when several fixtures back up together the shared sewer line is the likely culprit.
Can a blocked drain cause damage to my home?
Yes, surcharging water can flood bathrooms, undermine footings on sloping blocks and force sewage back through low fixtures, so a blockage that keeps returning deserves a camera inspection rather than another temporary clear.
Do you repair the pipe after clearing the roots?
Where the camera shows cracked clay joints or a collapsed section, we quote relining or replacement as a separate fixed price, so you can decide with the footage in front of you.
