Drainage Davidson: Every Drain, Sewer and Stormwater Line Sorted
1000+ five-star reviews
Drainage is the trade this suburb keeps us busiest on. Between root pressure from a heavy native canopy, the ridge-and-gully shape of former quarry land, and pipes as old as the streets above them, the drains under Davidson work harder than almost anywhere else on the Northern Beaches.
This hub is where that work lives. Six pages cover every drainage problem a local home can develop, from a slow fixture to a sewer run needing relining.

When to call: matching the symptom to the right page
Drainage faults announce themselves differently depending on which line is involved, and the fastest fix starts with the right door.
One fixture draining slowly
While everything else runs freely usually points to a local blockage, and the blocked drains page covers the clearing, jetting and diagnosis.
Several toilets backing up and gurgles through the house
Point at the main sewer line, which is blocked sewer territory and needs bigger gear.
Water pooling in the yard or near downpipes after rain
Is stormwater work, and the stormwater page covers pits, lines and gully catchments.
The same drain blocking again and again
Needs a camera before another clearing, so start at CCTV drain inspections.
A known break, root mass or collapsed section
Is where pipe relining and drainage repair and installation come in.
If water is coming back up through a floor drain or a toilet right now, treat it as an emergency and head to the emergency plumbing hub instead. Come back here once the immediate mess is handled.
Roots, ridges and old quarry ground: why drainage here is its own trade
Two facts explain most of the drainage calls we take from this suburb.
The canopy
The ground
Put those together and drainage becomes a maintenance fact of life rather than an occasional nuisance. The leaf fall that makes the autumn streets so beautiful also packs gutters, pits and downpipes, and every heavy Sydney downpour washes more of it into the lower lines.
Clearing a drain is only half the job here. The other half is diagnosing why it blocked, and that is why this hub leads with cameras and ends with relining.
The drainage directory: six pages, every line covered
Everything below is a page of its own, with the full detail on diagnosis, method and pricing structure.
Drainage repair and installation
Fixing broken lines and installing new ones, including falls that work with the slope of the block.
Blocked drains
The clearing service, from one slow fixture to jetting a main line, with the camera check that stops the blockage coming back.
Blocked sewer
Sewer-specific diagnosis and clearing when the whole house is telling you the main line is in trouble.
Stormwater
Pits, spoon drains, absorption lines and the gully catchments that shed leaf litter in a downpour.
CCTV drain inspections
The camera down the line, the footage in your hands, the guesswork gone.
Pipe relining
Repairing broken lines without digging, no wrecked gardens.
Stone, shale and the streets where the lines run deep
The second local angle worth knowing before you pick up the phone is the ground your drains sit in.
Rock and shale country
Catch it early
The character streets tell the story. Stone Parade and Borgnis Street run along the higher ground where the falls are kinder, while the blocks stepping down toward the gully country carry the longer, steeper runs that concentrate debris at the lowest points.
If your home sits at the bottom of one of those gully sections, your drainage has a harder job than your neighbour's up the ridge. It deserves a maintenance rhythm to match.
The six services, one at a time
Drainage repair and installation
Broken, bellied or badly fallen drainage lines get properly repaired here, and new lines go in with falls that follow the land rather than fight it. Repairs range from spot fixes at a single joint to full line replacements, and every option comes priced in writing before excavation or relining begins.
Blocked drains
The clearing service runs from a shower recess that will not empty to a main line backing up, using drain machines and water jetting sized to the fault. Roots from the suburb's heavy canopy are the leading recurring cause, so each clear finishes with a camera check.
Blocked sewer
When several toilets gurgle, the yard smells of sewer gas or the lowest bathroom floods first, the main sewer line is the suspect. This page covers the sewer-specific diagnosis, the clearing gear a main line needs, and the honest conversation about repair versus relining once the camera shows the cause.
Stormwater
Stormwater work here means pits that take the runoff, lines sized for bushland catchments, and solutions for the gully sections where leaf litter and silt concentrate in heavy rain. We clear, repair and install, and we size everything for the downpours rather than the drizzle.
CCTV drain inspections
The camera goes down the line and the footage comes up on screen, showing you the roots, the offset joint or the collapse exactly as it sits. For recurring blockages, pre-purchase checks and disputes about whose responsibility a fault is, the recording settles the question with evidence.
Pipe relining
Relining threads a resin-saturated liner through the damaged pipe, where it cures and leaves a brand-new pipe inside the old one. On large blocks with established gardens and rock ground, it is often the difference between a two-day repair and a two-week excavation, and it carries its own warranty.
How we diagnose: from camera to jetter to the relining call
There is a sequence we follow on almost every recurring drainage job, and knowing it helps you understand what you are paying for.
Step one is the camera
Step two is the clear
Step three is the decision
Signs by property type: what your block tells you
Older bush blocks backing the reserves
Renovated homes on the ridge streets
Homes at the bottom of the gullies
What the trees, soil and storms mean for your drains
The bushland-interface setting shapes drainage here in three specific ways.
- The canopy feeds the lines Eucalypt and liquidambar leaf litter enters gutters, pits and downpipes year-round, with the autumn fall the heaviest single event.
- The soil punishes digging Rock and shale ground makes excavation expensive, which shifts the value of every repair toward relining and early intervention.
- The storms find the gullies Intense downpours concentrate stormwater in the lower catchments, so those lines get sized, cleared and maintained with the worst rain in mind, not the average.
None of this is bad news. It is just the honest local picture, and it is the difference between a plumber who clears a drain and one who keeps it clear.
How it works
From the first call to the finished line

Call us and talk to a plumber
Speak to a licensed plumber, not an answering machine. Tell us what's going on and we'll tell you what happens next.
- 02
We turn up when we say we will
Your plumber arrives on time, in a stocked van, ready to start, not ready to have a look and come back next week.
- 03
Fixed price before we lift a spanner
You get the full price in writing before any work begins. No surprises, no obligation. If you say no, that's fine. The call out cost you $0.

The price we quote is the price you pay. No exceptions
Every job is priced upfront, in writing, before work starts. Weekend or weekday, day or night, with no overtime surprises.
$0 Call Out Fee
Getting us to your door costs nothing. You only ever pay for work you've approved.
Licensed & insured, Lic #275278C
Every plumber on the team is fully licensed and insured. Your compliance certificates are sorted, every time.
Lifetime Labour Warranty
Our workmanship is guaranteed for life. If it's not right, we come back. No questions. No cost.
What the fix costs, and when you find out
- $0 call out: the assessment and quote cost you nothing
- One fixed price, in writing, before any work begins
- No overtime rates: nights and weekends priced the same way
- Card, cash and payment plans accepted

Drainage quoting has one extra step worth knowing. Where a diagnosis genuinely needs footage, the camera fee is part of the conversation before anything runs, and the price of the fix is quoted from what the footage shows, never from a guess.
Good questions, straight answers
Questions Davidson locals ask about drainage
Do tree roots cause most of the drain blockages here?
They cause a large share of them, because the heavy eucalypt and liquidambar canopy on the suburb's large bush blocks sends roots into joints in older drainage lines, and we clear them with jetting and confirm with a camera.
What is the difference between a blocked drain and a blocked sewer?
A blocked drain usually affects one fixture or the stormwater side, while a blocked sewer backs up several toilets and gurgles through the whole house, and each gets its own diagnosis and its own page on this hub.
How does a CCTV drain inspection work?
We send a camera down the line and watch the footage in real time, then show you the recording so you can see the roots, the break or the collapse yourself before deciding on the fix.
Can you fix a broken drain without digging up the yard?
Often, yes, because pipe relining threads a resin liner through the damaged pipe and cures it there, which suits established gardens and bush blocks where excavation would wreck the setting.
Why do the gully sections flood in heavy rain?
The ridge-and-gully terrain on former quarry land concentrates runoff and debris in the lower drainage lines, and bushland catchments shed leaf litter and silt during downpours, choking the stormwater side.
Do you charge a call out fee to diagnose a drainage problem?
No, the call out is $0, and you receive a fixed written price covering the complete fix before any work begins, with no obligation to proceed.
Is stormwater work the council's responsibility or mine?
The pipes within your property boundary are generally yours to maintain, and we can advise where your responsibility ends and the council's begins once we camera the line.
The rest of the network, one door each
Drainage is one of four doors. The home page gathers everything, the general plumbing hub covers the fixtures and fittings side, and the hot water hub handles the units this suburb keeps replacing.
The emergency plumbing hub handles the after-hours versions of everything, including a toilet overflowing or a burst line. For those, it routes you straight.
