Tree roots don’t like wet feet
Even though tree roots get into pipes seeking water, they don’t like to be in the water all the time.
Excavated soil allows the fine tree roots to move along the top of and into the pipe joints and then down into the water flow.
In permanently water charged ground, tree roots rarely appear in the sewer because they don’t like to be continually immersed in water.
How tree roots get into pipes #2
In my last post I described how tree roots can easily travel through soil that has been loosened by excavation to accommodate your pipe installation.
Do you know why tree roots grow in sewer pipes from the top of the pipe joints?
Condensation is formed when we run water from our water pipes, through our drains; especially when we have a hot shower, wash our clothes or dishes in hot or warm water.
When the warm water enters the drains buried in the cold earth, condensation is formed, and it gathers on the inside top of our sewer pipes and drains.
The tree roots moving through our already loosened soils can now move along the top of the pipelines and are attracted to the warmth and moisture inside. All they need now is a way into the pipe.
This 1.58sec clip shows how.
Tree roots will travel to find your pipes
Quite often a sewer blockage can be caused by the roots from trees that are not even on your property.
Tree roots will travel great distances to seek moisture and nutrients readily found in sewer pipes, especially during periods of extended drought. Amazingly in some cases the roots will travel from the base of the tree up to 3 times the height of that same tree. So a 15 metre high tree will spread its roots up to 45 metres from the base of the tree.

What is a blocked drain?
A drain is an outlet where water can be piped away from a plumbing fixture like a toilet or WC, a basin, bath or shower, a kitchen sink, laundry tubs or an external drain, known as a gully.
Stormwater drains can take discharge from roofing guttering and pits and grates installed to take runoff water collected from hard surfaces.
A blocked drain is usually referred to when waste water accumulates around any of the drains and can not be evacuated.
Most drains run to either sewer or stormwater mains that are assets of Water authorities, municipal councils and the cities and towns across the country
Most blockages are generally caused by tree roots, grease, hair, sanitary products, dirt and debris or a multitude of foreign items including broken pipes.
Blocked drains are the responsibility of the property owners.
This series of blog posts will be aimed at blocked drain basics.
We will discuss who owns the drains, how to maintain them, what you should and should not put in your drains and what to look out for if your drains are about to block up.
We will look inside pipes, show you a drainoscopy or pipe survey so you know what it’s like in the network of pipes under your homes and buildings.
I encourage your feedback, so please ask questions and we will answer them promptly!
5 Things You Can Do To Prevent Blocked Drains
Here are a few measures that go a long way to prevent roots from infiltrating and destroying your pipes.
- Use pipes made of Polyvinyl chloride (PVC) for new and replacement drains. PVC pipes are strong enough to repel the tree roots. Experts agree that PVC is the best material for reducing the risk of tree root blockages.
- Don’t plant trees near pipes. This seems simple enough, but many home and business owners don’t realize what constitutes as ‘near’ when we’re talking about tree roots. Many Australian trees have roots with an incredibly wide spread.
- Choose proper foliage. Eucalyptus, for example, can have roots systems that spread out as much as 60 meters. Hills Weeping Fig, on the other hand, can have a root spread as small as 6 meters.
- Maintain your pipes. Wear and tear, cracks, and leaks can cause nutrient-rich water to seep into the soil around your pipes. This attracts tree roots like mad.
- Routinely check and clear your sewer drain. Though roots can be attracted to any type of water-bearing line, they are most often lured towards sewer drains. Have an expert come by and clear roots out of your pipes before they become a big problem.
