Is it the sewer or just one fixture?
One slow basin points at a fixture trap. Several fixtures misbehaving at once points at the sewer line itself. Watch for these:
- Water climbing up the shower drain each time the toilet flushes
- Gurgling from the laundry trough or basin while the bath drains
- More than one toilet backing up on the same day
- Overflow around the inspection shaft or a wet patch on the lawn above the line
If you see more than one of those, stop running water inside and treat it as urgent. A backed-up sewer does not wait politely, and the lowest fixture in the house copes it first.
How we clear a sewer
Footage picks the method, so the camera always goes in before the cutter:
- 01
Find the line and open the access
We locate the inspection shaft or boundary trap and get a clear entry point before anything else happens.
- 02
Camera the pipe first
The CCTV drain inspection shows what is sitting in the line, whether it is roots, sediment or a collapse, and what the pipe behind it can take.
- 03
Clear it with the right tool
High-pressure jetting slices roots and flushes sand and grease, and the electric eel handles tougher knots where the jetter needs backup.
- 04
Film it again afterwards
The follow-up footage proves the sewer is flowing and flags any split joint that needs a repair quote.
That last step matters more than most owners expect. Clearing a sewer without filming it afterwards leaves you guessing whether the same fault will be back next month.
What moves the price of a sewer clear?
"Professional, hardworking and friendly lads. Replaced our sewer line and got very filthy under the house." Annie
Depth, pipe material, and how much of the line is affected drive the figure more than anything else. A shallow PVC run in the front yard is a quicker job than a deep clay line under a house. The main factors:
- How deep the pipe sits and how far the run extends to the main
- Clay pipe, which needs gentler clearing, versus modern PVC
- Where the choke is reached from, under the house versus an open yard
- Whether the footage shows a structural fault that needs pipe relining or excavation
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead. The sewer price is set once the camera has shown the cause.
Why local sewers block twice
Much of the post-war housing stock here still carries earthenware sewer pipes, and a cracked joint on a low block lets groundwater seep in whether or not anyone is running a tap. That steady inflow carries fine sand along the pipe floor and narrows the channel until solids start snagging.
The low blocks wear it worst. Streets near Green Point Foreshore Reserve sit barely above lake level, where groundwater runs highest and older lines cop it hardest. A sewer that blocks twice in a year usually has a structural cause, and the camera tells us whether relining beats digging.
When we're not the right call
A choke in the shared street main belongs to Hunter Water, not to you. If the footage puts the fault beyond your property, the plumber gives you Hunter Water's faults contact. Sewage coming up in several neighbouring yards at once usually points the same way.
Sewer questions before you book
Why does my sewer keep blocking here?
Repeat blockages usually trace back to cracked earthenware joints in the post-war pipe stock. Groundwater on the peninsula sits close to the surface, so it keeps feeding sand through those cracks until solids snag again.
Can a blocked sewer damage my house?
It can. Sewage backs up through the lowest fixtures first, usually a shower or floor waste, and on sandy ground the moisture soaks into sub-floor space quickly. Clearing the line early costs far less than drying out and cleaning up afterwards.
Will the sewer be filmed again once it is clear?
Yes. Filming happens twice, once to find the choke and once after it is gone, and you watch the second run with the plumber to judge whether the old clay is fit to keep.
Do you clear sewers outside Belmont too?
We do. The same run covers Belmont North, Redhead, Belmont South and Valentine, and every job gets the same fixed up-front quote and the 365-day warranty on all work.
Where the rest of the drainage work sits
A sewer clear is one part of the drain work we cover.
If the line misbehaving is a stormwater run rather than the sewer, our stormwater drains page explains how those systems behave on low ground. Where the footage shows damage instead of a clog, pipe relining can seal the damaged length without digging it up.
