Stop the Refill
We shut the cistern's inlet tap or the meter stopcock, whichever stops the feed fastest, and confirm the pan has settled before anyone starts on the fittings inside the cistern.

First Moves at the Pan
Water rising at the pan keeps coming until something stops it, so do these in order:
Do not flush again to test it, because every flush adds to the water already down.
- 1
Lift the lid off the cistern
and hold the float down. If the refill stops, the valve is the problem.
- 2
Close the inlet tap
on the small pipe feeding the cistern, usually near the wall.
- 3
Shut the meter stopcock
if the pan keeps rising. That stops every fixture feeding the flood.
- 4
Stay clear of power points near the wet floor
, and call (07) 3067 4119.

What Makes a Toilet Overflow
Most overflows come from one of four places, and they run from a five-minute job to a real one:
A refill valve that never shuts
The float sits too high or the valve has worn, so water runs into the pan non-stop.
A jam in the pan or trap
Paper wedged in the S-bend, or a dropped item caught in the trap, means one flush comes straight back up.
A blocked sewer line
Everything downstream chokes, and the lowest fixture, nearly always the toilet, is where it shows.
A choked shared main
One blocked stack in a unit block can back up into several homes at once, and it cannot wait for morning.
When more than one fixture runs slow at the same time, the fault sits downstream of the toilet, and that is the blocked sewer end of the trade.
What You Can Safely Check
There is a short list worth checking yourself, and a short list to leave alone:
The cistern water level
It should sit below the top of the overflow pipe inside the cistern.
The inlet tap
Turn it fully off and confirm the cistern stops filling.
The gully outside
If the grated drain near your boundary is also backing up, the choke is in the sewer line.
Other fixtures
Run a tap or flush a second toilet and listen for gurgling in the pan.
Skip the drain chemicals. They rarely shift a real blockage, they make the water unsafe for whoever works on the line, and they can eat at old clay further down.
When It Cannot Wait
Sewage spilling inside the house is a hygiene problem before it is a mess, and it worsens while it sits. Call straight away if:
- the water is actively rising
- a shared main serving a block of units is involved
- the overflow has reached carpet or a hallway.
We're available 24/7, and there is no extra charge for nights, weekends or public holidays. If it can safely wait a few hours for a booked visit, say so when you call and we will set a time.
Clay Joints, Grease and Storms
The drain stock under this suburb is older than most of its kitchens, and that shapes the overflow calls we take:
Clay drains under the character homes
The pre-1947 Queenslanders and cottages in the pockets near Keylar Street still drain through clay lines laid in short sections, and every buried joint is a spot where fine roots grab hold. A sewer that chokes at a root-bound joint backs up into the lowest fixture, which is usually the toilet.
Grease from the food strip
Fat from the Blackwood Street cafes thickens in the shared mains, so an overflow in a home near that strip often arrives after a busy evening of trade.
Storms loading the slopes
The streets here fall toward Kedron Brook, so a quick storm cell that soaks every yard can push a marginal sewer over the edge, and the overflow arrives with silt in it.
Telling us your street and your style of house when you call puts the right gear on the van the first time.
The Overflow Work We Handle
An overflow call runs from stopping the water to proving the line is clear, and these four jobs cover almost every overflowing toilet we attend:
Clear the Pan
A plunger or a closer tool shifts most pan and trap blockages during the visit, and we flush-test afterwards so you can see the line running before we pack up.
Clear the Sewer
Where the choke sits further down the line, we shift it and then put the camera down the run, because a patched blockage above cracked clay only buys weeks before the next backup.
Make It Safe
Once the overflow stops we check the subfloor, the nearby fittings and the gully outside for trapped water, so nothing keeps seeping into the house after we go.
Common Causes Behind the Flood
Four causes sit behind most of the overflow jobs we attend, and each one has a different fix:
Running Cistern
A worn inlet valve or a float adjusted too high sends water down the overflow pipe without stopping; fitting a new valve ends it, and the part itself costs little.
Blocked Trap
Paper packed into the bend or something fallen from a pocket jams the pan's trap so the water returns with the first flush; most of these clear on the visit.
Root Intrusion
Fine roots grab the joints of old clay drains under the pre-1947 homes, and the first sign on a quiet street is often the toilet gurgling or backing up.
Shared Main Choke
In a unit block one choked stack backs up into several apartments at once, and the lowest bathroom floods first; naming your building when you call helps us bring the right gear.
Why a Fast Response Matters
The damage is done in the first hour, and the difference between a quick stop and a slow one is usually measured in flooring:
Water travels
Overflow water runs along floors, into subfloors and down wall cavities, and a spill stopped in twenty minutes is a mop-up while an overnight one is a restoration bill.
Health comes first
Toilet water on the floor is a genuine hygiene risk, especially with kids or pets, and it should be cleaned up properly, not just dried.
The cause gets worse
A root-choked sewer or a failing valve never fixes itself, and the same overflow that came tonight comes back heavier next time.

Questions on Overflowing Toilets
Call (07) 3067 4119Why does my toilet overflow when I flush?
Nearly always a blockage downstream: the pan, the trap, or the sewer line, so flushed water has nowhere to go and comes back up; in Mitchelton it is often roots at an old clay joint.
Should I turn the water off at the cistern or the meter?
Start with the little inlet tap beside the cistern if the refill keeps running, and shut the main stopcock at the meter if the pan itself is rising; either stops fresh water feeding the flood.
Does Urban Utilities fix a blocked sewer in Mitchelton?
Urban Utilities maintains the public sewer and water mains, but the pipes on your side of the connection are yours, so a choke in your own sewer line is our job, not theirs.
Do the old clay drains under Mitchelton's character homes change the fix?
They can, because the pre-1947 homes in the character pockets often drain through old clay pipes in short lengths, so we clear them with care and put the camera down before calling the line sound.
Do you charge extra to come out at night in Mitchelton?
No, there is no extra charge for nights, weekends or public holidays, we are available 24/7, and every job comes with $0 call-out fees and flat-rate pricing.

Ring (07) 3067 4119, tell us the street name and what the toilet is doing, and we can arrange a time, quote a flat rate before starting, and stock the parts most likely needed for a home like yours.
