Clearing a Blocked Drain with High-Pressure Water Jetting
Our team attended a property in Glenwood to investigate a blocked drainage line that was preventing wastewater from flowing correctly through the property's underground drainage system.
Using professional high-pressure water jetting equipment, we cleared the blockage, restored normal drainage flow, and assessed the condition of the existing pipework to determine whether any underlying issues required further attention.
While many people think blocked drains are simply caused by "something getting stuck," the reality is that a blockage is often a symptom of a larger problem developing within the drainage system.
Why Do Drains Become Blocked?
Blocked drains can occur for many different reasons depending on the type of pipe and where the blockage is located.
For sewer drains, common causes include:
- Tree root intrusion
- Grease and fat build-up
- Wet wipes and sanitary products
- Foreign objects flushed into the sewer
- Ageing or damaged pipework
Stormwater drains can become blocked by leaves, sediment, garden debris and soil that gradually build up inside the pipe over time.
In many cases, the blockage develops slowly. Homeowners might first notice water draining more slowly than usual before toilets begin gurgling, floor wastes overflow, or wastewater starts backing up around inspection openings.
Why We Use High-Pressure Water Jetting Instead of a Drain Snake
One of the biggest misconceptions about blocked drains is that every blockage can be cleared with a drain snake.
While electric drain machines still have their place, high-pressure water jetting is now considered one of the most effective ways to clear underground drainage systems.
Rather than simply punching a hole through the blockage, a water jetter uses highly pressurised water to scour the inside of the pipe.
This process removes:
- Grease build-up
- Sludge
- Tree roots
- Soap residue
- Food waste
- Sediment
- Loose debris
Instead of leaving material behind to cause another blockage a few weeks later, high-pressure jetting cleans the full internal diameter of the pipe, helping restore proper flow.
For many drainage systems, this provides a much more thorough clean than traditional mechanical clearing equipment.
Clearing the Blockage
For this Glenwood project, our team accessed the drainage system through the existing inspection openings before introducing specialised high-pressure jetting equipment into the affected pipework.
The blockage was progressively broken down and flushed through the drainage system while the line was continuously monitored to ensure water flow was returning to normal.
Once the obstruction had been removed, the entire section of pipe was thoroughly flushed to remove any remaining debris and improve the overall performance of the drainage system.
Testing confirmed that normal flow had been successfully restored.
Clearing the Blockage Doesn't Always Mean the Problem Is Gone
One thing many homeowners don't realise is that clearing a blocked drain doesn't always fix the underlying cause.
If a drain has become blocked because a pipe has cracked, collapsed or been invaded by tree roots, the blockage may eventually return if the damaged section isn't repaired.
That's why professional drain clearing isn't just about restoring flow—it's also about assessing the condition of the drainage system while the blockage is being removed.
During this project, the pipework was monitored throughout the clearing process. Where there are signs that damaged or collapsed drainage may exist, further investigation or repair can be recommended before the problem develops into a much larger and more expensive failure.
Early intervention often saves homeowners from repeated emergency call-outs and recurring blocked drains.
