Tree roots in your pipes and sewers.
Tree roots naturally seek out moisture — which often leads them straight into underground pipes, sewer lines and stormwater drains. Once inside, they grow, block and damage the system, especially in older pipes with cracks or loose joints.

Signs you have a tree root blockage
Identifying tree root intrusion early can save you from serious plumbing damage. Look for these common indicators:
Frequent clogs
Repeated clogs — especially in outdoor or below-ground drains — often point to roots.
Slow draining water
Water draining slowly from sinks, tubs or toilets can indicate a root intrusion in the pipes.
Gurgling noises
Gurgling from your fixtures may mean air is trapped by root interference.
Foul odours
Unpleasant smells from drains can indicate roots trapping decomposing organic matter.
Wet spots in your yard
Unexplained wet or lush patches can signal a sewer line leak caused by roots.
Roots follow the water
Tree roots are drawn to the moisture in your pipes. They enter through small cracks, loose joints or other openings — then thrive on the water and nutrients inside.
Where roots invade
Sewer lines
The most common target, thanks to the moisture and nutrients in wastewater.
Stormwater pipes
Roots invade and block drainage systems, especially older or damaged ones.
Water supply pipes
Leaks or cracks in older water lines attract roots seeking moisture.
Irrigation pipes
Ageing or damaged irrigation systems give roots an easy way in.
What it can lead to
- Severe blockages — roots form dense mats that restrict flow, causing slow drains or complete backups
- Pipe damage — the pressure from expanding roots cracks or breaks pipes, leading to costly repairs
- Sewage leaks — infiltrated lines leak, with wastewater pooling in your yard
Best methods for tree root removal
If you suspect tree roots are behind your blocked drains, we have proven ways to deal with them:
Mechanical root cutting
Specialised cutting equipment clears away roots that have infiltrated your sewer lines, restoring normal drainage.
Hydro jetting
High-pressure water jets clear out roots and debris, leaving a clean and clear system.
Root barrier installation
Barriers installed around your sewer lines deter tree roots from encroaching again.
Pipe relining
Where damage has occurred, relining reinforces the pipe and prevents future root infiltration.
How to prevent tree roots in sewers
A few smart habits go a long way toward keeping roots out of your plumbing:
Choose wisely when planting
Avoid planting trees near sewer lines — or select species with less invasive root systems.
Install root barriers
Adding root barriers during landscaping redirects growth away from your pipes.
Regular maintenance
Routine inspections and cleaning catch potential intrusions before they become major problems.
Monitor your yard
Keep an eye out for excess moisture or wet spots — early evidence of a sewer issue.
Troubleshooting this problem
Suspect roots are blocking your drains? A few checks and DIY steps you can try first:
- 1
Inspect your yard
Look for visible roots or wet areas that may indicate a sewer line problem.
- 2
Check for slow drains
Monitor your fixtures for slow drainage, particularly in outdoor areas.
- 3
Test for odours
Stay alert to foul smells coming from your drains — a classic sign of root intrusion.
- 4
Try a root killer
Chemical root-killing solutions can help with minor intrusions in the pipes.
- 5
Flush with hot water
Regular hot-water flushes help keep drains clear and reveal early signs of blockages.
