Why Do Drains Keep Blocking? Understanding and Solving Persistent Drainage Issues
Common Culprits Behind Persistent Blockages
Wet Wipes and Sanitary Items
Despite what packaging might claim, wet wipes don't break down like toilet paper. They're actually the number one cause of drain blockages in Australian homes, creating massive problems in our sewerage systems.
Tree Root Infiltration
Tree roots naturally seek out water sources and can penetrate pipes through tiny cracks or joints, creating significant obstructions over time.
Old Terracotta Pipes
Many older Australian homes still have terracotta pipes, which can:
Crack and collapse over time
Allow tree root infiltration more easily
Create ongoing drainage issues due to deterioration
Construction Debris
A growing problem, especially in new build areas:
Sand and sediment from construction sites
Concrete washout
Building materials that find their way into drainage systems
Other Common Causes
Hair and soap scum in bathroom drains
Grease and fat deposits in kitchen pipes
Food waste accumulation
Foreign objects
Warning Signs of Persistent Drainage Problems
Keep an eye out for these tell-tale signs:
Slow-draining sinks and bathtubs
Unpleasant odours coming from drains
Gurgling sounds in pipes
Water backing up in multiple fixtures
Recurring blockages despite regular cleaning
Professional Solutions for Lasting Results
Professional plumbers use CCTV camera inspections to identify the exact location and nature of blockages, ensuring targeted and effective treatment.
High-Tech Clearing Methods
Hydro-jetting technology for powerful cleaning
Specialised root removal equipment
Professional-grade drain cleaning solutions
Pipe relining for damaged sections
Prevention is Better Than Cure
To avoid future blockages:
Properly dispose of wet wipes in bins, never flush
Install drain guards to catch debris, especially during construction
Regular gutter cleaning to prevent overflow and blockages
Schedule periodic professional inspections
Be mindful of big trees or root systems nearby
Summary
Understanding what causes persistent drain blockages helps you take the right preventative steps. Whether you're dealing with old terracotta pipes that need replacing or recurring blockages that require professional attention, it's important to address these issues promptly.
