Can Tree Roots Affect Your Plumbing or Septic System?

Yes, and it’s more common than most homeowners realise.

If you’ve ever dealt with slow drains, recurring blockages, or unexplained plumbing issues, tree roots could be the hidden cause. In many WA properties, especially older homes or rural blocks, tree roots are one of the leading reasons pipes and septic systems fail.

At Harvey Tree Care, we regularly work alongside plumbers to fix the root cause of these problems, not just the symptoms. Here’s how tree roots affect plumbing and septic systems, the warning signs to look out for, and what you can do about it.

Why Tree Roots Target Pipes and Septic Systems

Tree roots naturally grow towards moisture and nutrients. Underground pipes, septic tanks, and leach drains provide exactly what roots are looking for. Even a tiny crack or joint in a pipe is enough for roots to enter.

Once inside, roots continue to grow, slowly filling the pipe and trapping waste, paper, and debris. Over time, this can lead to complete blockages or pipe failure.

Common systems affected include:

• Older clay or earthenware pipes
  
• PVC pipes with aging joints
  
• Septic tanks and leach drains
  
• Stormwater and sewer lines

Warning Signs of Root Damage

Root intrusion often starts quietly. Many homeowners don’t realise there’s a problem until the damage is already advanced.

Watch for signs such as:

• Slow-draining sinks, showers, or toilets
  
• Frequent blockages that keep returning
  
• Gurgling noises from pipes
  
• Sewage smells in the yard or near drains
  
• Wet or soggy patches of soil around septic areas
  
• Toilets backing up after rain

If these issues keep coming back after plumbing repairs, roots are likely the cause.

Clearing Pipes vs Fixing the Root Problem

Plumbers can often clear roots temporarily using jetting or cutting tools. While this restores flow, it does not stop roots from growing back. In many cases, blockages return within months.

This is where professional tree root removal becomes essential. Removing or managing the root system stops the problem at its source and prevents repeated plumbing damage.

How Root Removal Machines Help

At Harvey Tree Care, we use specialised root removal machines designed to remove invasive roots safely and effectively.

These machines allow us to:

• Grind and remove roots near pipes and septic systems
  
• Clear root systems when grinding stumps
  
• Access tight or confined areas with minimal disruption
  
• Prevent regrowth that causes recurring blockages

Our approach focuses on solving the problem permanently while protecting surrounding structures and landscaping.

When Tree Removal Is the Best Option

In some cases, root pruning alone is not enough. Full tree removal services may be required when:

• The tree is planted directly over pipes or septic lines
  
• Roots have caused repeated pipe failures
  
• The tree is unhealthy or unstable
  
• The cost of ongoing plumbing repairs outweighs removal

Our experienced arborists assess each situation carefully and provide honest advice on the safest and most cost-effective solution.

Common Trees Linked to Plumbing Issues in WA

Certain species are more aggressive root growers than others. In WA, problems often come from:

• Large gums
  
• Figs
  
• Willows
  
• Some wattles
  
• Fast-growing ornamental trees

Knowing what’s planted near your pipes is key to preventing future damage.

Prevention Tips for Homeowners

To reduce the risk of root damage:

• Avoid planting trees near sewer or septic lines
  
• Choose species with non-invasive root systems
  
• Schedule regular tree inspections
  
• Address early plumbing issues before they escalate
  
• Remove problematic stumps completely to prevent regrowth

Early action is always cheaper than emergency repairs.

Frequently Asked Questions

Can roots be removed without killing the tree?
In some cases, yes. Targeted root removal can be done safely, depending on the species and location.

How do I know where my pipes run?
Plumbers can locate pipe paths using cameras or mapping tools. We often work alongside them for coordinated solutions.

Will stump grinding stop root problems?
Grinding removes the stump and major root mass, which helps prevent future growth, but existing underground roots may still need treatment.
