Call Now0493 824 176
Signs you may notice
- Several toilets or drains back up together
- An outdoor gully overflows
- Wastewater appears at the lowest fixture
- The blockage returns after temporary clearing
Possible causes
- Tree-root intrusion
- Broken, displaced or collapsed pipework
- Wipes and foreign material
- A belly, poor fall or accumulated debris
Symptoms help narrow the investigation; they do not confirm the cause on their own.
Diagnosis before equipment
Sewer blockages need controlled access and hygiene precautions. We locate a suitable access point, restore flow where possible, then inspect the line when recurrence or pipe damage is suspected.
A suitable sewer opening permits controlled clearing. Jetting and selected nozzles can remove many deposits, but a collapsed section or lodged object may need another method. A camera is more useful once the line can be seen.
Tools and materials
- Commercial high-pressure water jetter
- CCTV drain camera and locator
- Root-cutting and descaling nozzles
- Excavation and pipe-repair equipment where required
Selection depends on safe access, the obstruction and the actual pipe condition.
Safe first actions
Stop connected toilets, sinks, showers and washing appliances. Keep people and pets away from sewage and do not lift heavy or pressurised covers. Stay out of flooded plant rooms and report any nearby electrical hazards.
If wastewater is near electrical equipment, keep clear. Immediate danger needs the appropriate emergency service.
Clearing versus repair
Restoring sewer flow does not repair cracks, open joints or low sections. If evidence shows structural failure, locating the fault helps define a separate repair and reinstatement scope.
After the agreed work, flow is checked where appropriate and the findings, remaining limits and next steps are explained.
Sewer Drain Blockages: your questions
Why is the outdoor gully overflowing?
It may be where wastewater escapes from a downstream restriction. Its location does not confirm the exact fault. Stop connected water use and keep the area clear.
Is the blockage necessarily on my property?
Symptoms alone cannot establish the boundary or responsibility. The plumber investigates accessible private drainage and explains findings and any relevant limits.
Should I run a hose to test the sewer?
No while it is backing up. Additional water can spread contamination. Flow testing is performed when the line and working area are safe.
Can sewage backup affect a floor above the ground?
Shared or branch restrictions can affect different levels. Give the level and the sequence of symptoms rather than assuming the lowest outdoor point must be involved.
