Is It the Sewer or One Drain?
One fixture misbehaving points at that fixture. A sewer choke announces itself across the whole house:
- The shower or floor waste filling up when the washing machine pumps out
- A gurgling toilet, or the bowl sitting higher than normal after a flush
- The outside gully overflowing, or a sewer smell hanging around the yard
- The lowest fixtures in the house misbehaving first, then the rest
If two or more of those are happening, stop flushing and using the laundry, because everything you send down has to come back up somewhere.
What causes a sewer to block in Charlestown?
The causes follow the age of the pipes, and most local sewers share one:
Tree roots at the clay joints
Cracked earthenware that silts up
Grease and scale
Ground movement
How We Clear a Sewer
Four steps, and the camera is what turns a guess into a diagnosis:
- 01
Find the choke
We run the CCTV drain camera down the line from an inspection opening, so we know exactly where the blockage sits and what it is before clearing starts.
- 02
Clear the line
The jetter washes the bore back to the pipe wall, and the electric eel cuts root masses too dense for water alone.
- 03
Film it again
The camera goes back down to confirm the line is clean and show whether the joint or crack behind the trouble is still open.
- 04
Fix the cause
If the footage shows structural damage, pipe relining renews the pipe from the inside, and tree root removal deals with the source before it regrows.
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead. The camera decides whether you are paying for a simple clear or a structural repair, and you see that footage before you commit to either.
What drives the price of a sewer clear?
The figure follows what the camera finds, not a flat rate:
- Where the choke sits and how far down the line the equipment has to travel
- Whether it is soft waste, grease or a root mass threaded through a joint
- Whether the pipe itself is sound, cracked or collapsed
- The after-hours rate, when sewage is rising at night
One sewer program, one pipe age
The sewers under the postwar blocks nearly all share a birthday. Sewer reached Charlestown in one 1959 program, which put the clay house drains under these front yards into the ground together, and they are wearing out in the same decade. Add reactive clay that moves with wet and dry spells, and those old joints drop out of line, so a neighbour's sewer trouble is fair warning about your own. When the footage shows cracked, silted clay rather than a one-off choke, the lasting fix is relining or replacing that section, and we price both so you can choose with the footage in front of you.

When we're not the right call
Some sewer faults are not ours to quote. Hunter Water owns the public sewer main, so a choke past your property connection is theirs to clear, and you report it to them rather than paying us to touch it. The camera footage shows where the choke sits, so you have something to pass on.
Sewer questions locals ask us
Can I keep using the toilets while the sewer is blocked?
Not once sewage is rising in the lowest fixtures, because every extra flush has nowhere to go but back up. If the outside gully still drains and nothing indoors is rising, short use might be possible, but ring first and describe what you see so we can judge whether it can wait.
Why do sewers block more here than in newer suburbs?
Because nearly every house drain here went into the ground in the same 1959 program, the pipes share one age. Sixty-plus years of root growth and ground movement have opened the clay joints, and that is where most chokes begin.
Does the water authority fix some sewer blockages?
Yes. The public sewer main is Hunter Water's, so a choke in it is theirs to clear. When the camera shows the blockage past your property connection, you get that footage before paying for anything on the wrong side of the line.
How long does clearing a sewer usually take?
A simple choke in the house drain usually clears with the jetter or electric eel, and a second look on camera confirms it. When the old clay is broken or has caved in, clearing is only the first step, and a reline or a new length of pipe is quoted as its own job.
Book a sewer clear
Relining, jetting and stormwater all sit under the blocked drains hub, and drain jetting explains the clearing method in detail; if sewage is already coming up inside at night, ring for emergency plumbing. For taps, hot water and gas, the same plumber in Charlestown handles the lot.
