When it comes to disruptive blockages in your plumbing system, tree roots have garnered the reputation as the boogeyman. An insidious threat that seeks to destroy your pipes when it gets a chance. However, the truth is a little more nuanced.


It’s true that tree roots can cause major blockages and ruptures in your plumbing system, which can be costly. However, this isn’t an insidious issue and, with the right approach, it can be resolved before it becomes a serious problem.


Why Tree Roots Invade Your Pipes in Dry Weather


Tree roots naturally grow towards water and nutrients. Your pipes often contain moisture and organic material, which can create the perfect environment for nearby root systems. However, these ‘perfect conditions’ are usually triggered by small leaks or weaknesses that allow moisture to escape into the surrounding soil.


During periods of dry weather, this is exacerbated, as soil moisture levels decrease and roots naturally seek out more reliable sources of water. Tiny cracks, loose joints, and ageing materials (such as clay or older systems) are particularly susceptible to root intrusion.


Keep in mind that roots do not force their way into pipes;  instead, they take advantage of these existing openings. Once inside, they can access a constant flow of water and organic material, allowing them to grow rapidly from fine strands into thicker roots, leading to significant blockages and pipe damage.


Signs You May Have Root Intrusion in Your Drains


If tree roots have entered your drainage system, there are usually clear warning signs that will become noticeable over time. Here are a few to look out for:


Slow Drainage

If you notice your kitchen and bathroom sinks, showers, or toilet drains a little slower than usual, it may indicate a developing blockage from tree roots.


Gurgling Sounds 

These sounds usually occur when air trapped by roots is forced through narrow pipes. This symptom usually goes hand-in-hand with slow drainage, but it can also appear on its own.


Recurring Clogs

The odd blockage is often a right of passage for many homeowners, but if you notice you’re having to regularly deal with clogs, it may be because something is obstructing your drainage system.


Sewer Backups

In more advanced cases, wastewater may begin to back up into your entire plumbing system as tree roots significantly restrict or block the pipe.


FAQs Around Your Plumbing System and Tree Roots


Can I remove tree roots myself?

Unfortunately, DIY solutions only provide temporary relief and sometimes may not even work. The best solution is to call a plumbing professional to remove any root invasions in your pipes.


How to remove roots in your plumbing system?

One of the most common ways to remove tree roots is through water jetting. This method uses high-pressure water to blast through root blockages and does an excellent job of cleaning your pipes. Additional techniques utilised are CCTV inspections and pipe repair or relining when needed.


Are there proactive steps to ensuring my pipes remain free of roots?

Yes! One of the best ways we can do this is through regular drain inspections. This preventative measure is an excellent way to detect early signs of roots creeping into your pipes and can also help prevent major problems in the long-term.


Will the roots come back?

Yes. Remember, tree roots grow towards moisture and nutrients, so if structural damage is not repaired, the likelihood of these tree roots invading your pipes is quite high.


How quickly should you deal with tree roots?

Tree roots should be dealt with immediately. Even small root growth can expand rapidly once inside your pipes, leading to worsening blockages and potential pipe damage over time. The longer it is left, the more extensive and costly the repair can become. Early inspection and treatment are the keys to preventing serious damage.


How Clearpath Drainage Can Help?


The longer tree roots are left unchecked, the more damage they can cause to your pipes. Unfortunately, signs such as slow drainage and gurgling sounds are often mistaken for a simple drain blockage. The best way to get to the root of the problem is to call in a professional.
