Tree Roots, Block Drains... Why?

The most common cause of blocked drains, either sewer lines or storm water pipes are tree roots. Tree root growth can have a damaging effect on your plumbing services. Tree roots can break, crack or collapse your sewer pipes or stormwater drain pipes. Forcing a complete pipe replacement and all that it entails. Long downtime, excavation and increased costs. Tree roots in your plumbing services should be taken seriously.


Network Plumbing have identified 4 main reasons as to why, tree roots are drawn to your pipes and are the largest single cause of a blocked drain.


Underground


As most of our sewer pipes are buried underground, planting trees in close proximity to your sewer pipes... may result in those or surrounding plants finding their way into your plumbing systems. Pipes located underneath the ground do in many ways become fair game.


Source of Nutrients


Tree roots thrive in sewer pipes. The conditions create the perfect moist atmosphere for tree roots. Hot water, cool water and the nutrients inside your sewer drains naturally attract tree roots. The condensation that can build up around your sewer pipes can be likened to a beacon calling unto them.


Structural Integrity Of Your Plumbing Services


Do you know the age of your pipes? Are they earthenware pipes, durable PVC pipes or metal pipes? Each pipe material will present different risk factors. The offending tree roots, won't mind the type of material. If there is a way in, a tree root will find it. For example, rusting, cracked or misaligned pipes will be taken advantage of by tree roots.


Location Of Your Drainage System


Do you know the location of your sewer pipes or stormwater drains on your property? Are trees planted close by?


Did you know that tree roots can grow up to 2-3 times that of the radius of the tree's canopy... during dryer seasons this might even be up to 5 times that. Searching tree roots will travel. Knowing where your plumbing system is located will help you to identify potential risks. If you are considering your landscape and where to plant trees, also consider your plumbing service footprint. Plant trees at least 6 meters away from your service. This is a general rule of thumb. Avoid planting trees any closer than this.

Signs You Might Have Tree Roots In Your Sewer Pipes?

You guessed it, signs of a blocked drain will indicate if tree roots have entered your pipework. Why is this? As mentioned above, tree roots are one of the common causes of a blocked drain.


  • Slow to drain sinks
  • Strange toilet flushes
  • Smell or odours coming from your drain
  • Wet patches in your yard
  • Cracked driveways or pavers


A blocked drain is inconvenient but can also present health risks as well. A tree root can completely block your sewer line. The roots can retain material that passes into a drainpipe including tissue grit and other dangerous waste. They will then obstruct the whole pipe and that can contaminate the sewage line, potentially flood your home, and pose health and property damage.


How Will A Root Risk Analysis Help?

Network Plumbing has taken the time to assess how we might best serve our clients. Prevention is better than a cure, by taking advantage of our complementary service of a Root Risk Analysis you'll be acting before blocked drains become a pain point.

Our plumber will use their CCTV drain camera to inspect your pipes, identify any current or potential areas that might be at risk. The Root Risk Analysis checklist will help you determine your risk factor.


  • Drainage smells or odours
  • Slow draining toilets or sinks
  • Pipes that are over 20 years old
  • Trees with prolific root growth
  • Medium to large trees surrounding your property


If you can tick the box on any of these factors, reaching out to our trained professional plumber to assess your pipes will help to minimise any damage caused to your pipes.


The goal is to act before damage is caused by the tree root and therefore the blocked drain has gone too far. A tree root can take over an entire pipe, tree root damage can be significant. Clearing and acting to prevent tree roots from taking hold of your pipes will give you choices on a course of action when you're facing blocked drains. Sometimes when a pipe is so severely damaged the only solution may be a complete pipe replacement. Tree roots blocking are only one factor, the damage that can occur to your sewer line is another.

The Method To Remove Tree Roots

Tree root removal requires skilled plumbers. Removing tree roots sufficiently with the latest plumbing technology is a task Network Plumbing can handle. Our plumbers regularly and successfully clear tree roots from a stormwater drain to a sewer pipe throughout Sydney.


It entails much more than DIY fixes found on the internet. Myths like pouring weed killer down your pipes to kill roots is futile, by the time you've poured the weed killer, it's already making its way out to your main sewer line connection. This process is even worst when practised in your stormwater pipes, as your stormwater will not travel to a water treatment plant but out to a natural waterway instead.


Drain cleaning is more than flushing rock salt down your toilet in hope of drying out the tree roots blocking your drains. The quickest and cheapest method available isn't always the method that will lead to a permanent solution, just a temporary fix... if that?


Clearing roots once they have been located and identified can be undertaken in less than a few hours. Network Plumbing regularly employs the use of a high-pressure water Jetter.


Hydro jetting is a powerful and effective plumbing tool. Jet blasting can clear tree roots, dirt/sand, foreign objects and all matter of things that may have caused the blockage. All the roots will be cleared from your system. A hydro jet is environmentally friendly, not relying on the use of chemicals and in turn safeguarding our waterways.
