Everything You Need to Know About Plumbing Unblocking and High-Pressure Water Jetting

February 2nd, 2024

Unblocking and high-pressure water jetting are common plumbing procedures used to eliminate obstructions and buildup in pipelines. These interventions are crucial to ensure efficient water flow and prevent plumbing issues. Here’s everything you need to know about plumbing unblocking and high-pressure water jetting.


Unblocking refers to the removal of obstructions that impede water passage in pipelines. Obstructions can be caused by various factors such as hair, food residues, debris, grease, and foreign objects. Here are some commonly used methods for unblocking:


The plunger is a basic tool used to unblock sinks, basins, and toilets. By creating pressure and suction, the plunger can break down and eliminate obstructions.

Mechanical Snake (Furet mécanique):

A mechanical snake is a flexible rod with a corkscrew-shaped end that can be inserted into pipelines to break down obstructions. It is particularly effective for deeper blockages.

Chemical Unblockers:

Chemical unblocking products are corrosive solutions designed to dissolve obstructions. However, their excessive use can damage pipes and pose health risks, so it’s recommended to use them with caution.

Manual Cleaning:

For more severe blockages, manual cleaning may be necessary. This often involves disassembling pipes to access the obstruction and remove it manually.

High-Pressure Water Jetting:

High-pressure water jetting is a more advanced method that uses pressurized water to clean pipelines. It is a more powerful and effective solution, often employed in situations where traditional unblocking has not been sufficiently effective. Here’s how high-pressure water jetting works:

High-Pressure Water Jet:

Specialized equipment sends a jet of high-pressure water into the pipelines. The high pressure dislodges and eliminates obstructions, grease deposits, residues, and even plant roots.

Comprehensive Cleaning:

High-pressure water jetting not only clears immediate blockages but also removes accumulations along the pipe walls, ensuring smoother flow and preventing future issues.

Safe and Environmentally Friendly:

High-pressure water jetting is considered a safer and more environmentally friendly method than using chemical unblockers, as it doesn’t require the use of corrosive chemicals.

In conclusion, unblocking and high-pressure water jetting are essential plumbing procedures to maintain pipelines in good working condition. The choice between these methods depends on the nature of the obstruction and its location in the pipelines. It is always recommended to enlist the services of plumbing professionals for effective and risk-free interventions.
