Make It Safe
We shut off the water, contain the spill and find whether the fault sits in the pan, the branch line or the surcharged main, then say whose pipe it is.

Health first, plumbing second. Sewage on the floor is a hazard, so keep people and pets clear and work through the steps below. The emergency plumbing page covers the urgent calls we take, and Clontarf home lists everything we do.
Stop It Getting Worse
Before you do anything else, work down this list:
- 1
Stop flushing
Each flush feeds a pipe that is already full, and that water has to go somewhere, usually the floor.
- 2
Turn off the water at the toilet's isolation tap or the meter
The small tap behind the pan stops the cistern refilling; if water is surging from the bowl itself, close the main tap at the meter.
- 3
Keep the room clear
Keep children and pets out, and put towels or newspaper down on the route to the door to limit tracking.
- 4
Call us from a clean phone
Ring (07) 3067 4119, tell us what is overflowing and what you have turned off, and we will step you through the rest.

What Makes a Toilet Overflow
Most causes sit at the simple end of the scale, and the order below runs from the easiest clear to the biggest job, because checking the easy things first saves you money.
A blocked S-bend or trap
Paper, wipes or a dropped toy lodge in the pan's own bend. The simplest cause and the quickest to clear.
A blocked branch drain
The pipe carrying waste from your house to the street connection has a partial or full blockage, so water backs up and returns through the lowest fitting.
A surcharged sewer
Heavy rain pushes groundwater into old sewer joints until the whole system rises, and the water lifts out of gully traps and low-lying pans.
A collapsed line
The worst case: a broken branch drain needing excavation and replacement, which we diagnose before quoting.
What You Can Safely Check
A few checks are safe for anyone; anything beyond them needs a licensed plumber. Work through these, then call with what you know:
Try a bucket test
Pour a bucket of water straight into the pan. If it drains away slowly, the blockage is further down the line. If it surges straight back, the blockage is close to the pan.
Check other fittings
Run a basin tap and watch the shower floor or the yard gully trap. If several fittings back up together, the problem is the branch drain or the sewer, not the toilet.
Listen to the street
If neighbours report the same problem at once, the public sewer main may be involved, which sits on Unitywater's side, and we say so plainly if that is the case.
When It Becomes an Emergency
Sewage inside the house is always urgent. It becomes an emergency call the moment wastewater crosses a floor, surges repeatedly, or comes up in more than one fitting at once.
A single slow-draining pan that keeps its water in the bowl is a booked-job matter, not a midnight one. For the difference between the two, read burst pipes or the emergency plumbing page's triage guide.
Why Toilets Overflow Here
Clontarf's drains give an overflowing loo particular local causes, and knowing them changes the fix.
Old clay sewers
Old clay pipe accounts for the bulk of the sewer main under these streets, asbestos cement for much of the rest, and the branch drains serving the postwar houses date from the same era, so joints crack, roots enter and storm water surges through.
Low, wet ground
Council's acid sulfate mapping covers Yacht Street and Cornelius Street, where groundwater lies just below the surface, so a wet week quickly loads those old joints.
Storm routes
Council's flood overlay carries its higher hazard classes over Conley Street and Bell Street, and the storm tide layer picks up the foreshore streets off Hornibrook Esplanade, so summer storms are the recurring trigger for surcharge overflows.
Trees close to the pipes
The golf course and district parks put mature trees within a few metres of many earthenware drains, and roots push into the cracked joints from MacDonnell Road to the back of Kroll Gardens.
What We Do
Four things happen on an overflow call, and they happen in order, so you always know where the job stands and what the next step is before we take it:
Clear the Immediate Blockage
Paper or a dropped object lodged in the trap comes out on the spot, and we test the flush, the cistern and the inlet valve before calling the pan fixed.
Diagnose the Drain
Where the blockage sits further down, we run a CCTV drain inspection to find cracked joints, root intrusion or collapse, then show you the footage before any repair is approved.
Fix the Cause
Clearing a blockage without fixing what caused it just books you the same emergency next storm, so we quote the lasting fix, from blocked sewer clearing to full drain repairs.
Common Overflow Causes
Four causes cover nearly every overflowing loo we attend, and each has a different fix:
Paper and Wipes
Wipes and paper catch in the trap and the first bend of the branch drain, building a plug over days. Cleared on the spot, and the toilet flushes like new.
Roots in the Joints
Tree roots enter cracked earthenware joints and grow into a mat that catches everything passing through the line. We clear the roots and quote a repair that stops them returning.
Storm Surcharge
Heavy rain drives groundwater into sewer joints until the system backs up and spills from low gully traps. We confirm surcharge rather than blockage and advise on the right fix.
A Failing Cistern
A stuck inlet valve keeps filling a pan that cannot drain, so the water rises and spills over the rim. It is a quick toilet repair, not a drain job.
Why a Fast Response Matters
An overflowing loo does damage far beyond the bathroom floor, and the clock matters from the first spill, so here is what is at stake while the water is still coming:
- Health comes first. Sewage carries bacteria into flooring and along hallways, so the sooner the water stops and the spill is contained, the smaller the clean-up.
- Water travels down. A surcharge on a low-set slab home reaches floor coverings and cabinetry fast, while a high-set home sends it through to the space below, so minutes change the bill.
- The cause gets worse. A partial blockage becomes a full one, and cracked joints let in more roots and sand each season, so an early visit often turns a big job into a small one.

Questions Clontarf Households Ask About Overflowing Toilets
Call (07) 3067 4119Why does my toilet overflow when it rains in Clontarf?
Most of the sewer main beneath these streets is clay-era pipe with asbestos cement sections, so storm-driven groundwater surcharges the line and pushes wastewater back up into low pans and traps.
Do I own the drain causing my overflowing toilet?
The street sewer main falls to Unitywater, but the section of branch drain between your boundary and the connection point is yours, so we quote precisely the work needed on your side.
Can a blocked sewer make other Clontarf drains overflow too?
Yes, because one branch drain usually carries the toilet, bathroom and kitchen waste together, so a blockage sends water back up the lowest fitting, often the pan, the shower floor or a yard gully.
Should I keep flushing to test if the blockage clears?
No, because each flush feeds more water into a pipe that has nowhere to send it, so the level climbs and spills; stop flushing, keep people clear and ring (07) 3067 4119.
Does Council flood mapping affect toilet overflow risk on my street?
It can, because Council's higher flood hazard classes cover Conley Street, Bell Street and the foreshore storm tide zone, so storm-loaded sewers are a known risk on low ground here.
