Unblocking the Flow: The Power of Jet Blasting for Blocked Drains

jet blasting blocked drains

Blocked drains can be a headache, causing slow drainage, unpleasant odours, and gurgling sounds. If you’ve faced this issue, you’re not alone. But there’s a solution that goes beyond traditional methods – jet blasting or hydro jetting.

What is Jet Blasting?

Jet blasting or hydro jetting is a method of cleaning or surface preparation that involves the use of high-pressure water jets. It’s often used in industrial settings for tasks such as cleaning surfaces, removing paint or coatings, and clearing blockages from pipes or drains. The process typically involves directing a stream of water at very high pressure, sometimes combined with abrasive materials or detergents, to effectively remove dirt, debris, or unwanted substances.

In the context of cleaning pipes or drains, jet blasting can dislodge and flush away obstructions such as tree roots, grease buildup, scale, or sediment that may be blocking the flow. The high-pressure water jet can break up these blockages and carry them away, restoring proper flow and function to the system.

How does jet blasting work?

Jet blasting is a process that uses high-pressure water jets to break apart and flush away any obstructions within pipes, ensuring that plumbing systems are clear of any blockages and maintaining their integrity.

  1. The first step a plumber will perform is to assess your drain using cameras or other inspection tools and determine the type and location of the blockage.

  2. Before jet blasting the drain, the plumber will prepare the surrounding area. This includes ensuring access points are open and safety measures are in place. Jet blasters use specially designed nozzles that emit highly pressurised streams of water. These high-pressure jets can vary in intensity and pattern, allowing for customisation based on the nature of the blockage.

  3. The high-pressure water jets will be directed precisely to target specific blockages within the pipes. This targeted approach ensures that the force is applied directly to the obstruction, maximising the effectiveness of the process.

  4. The forceful water jets serve to dislodge and break down debris, including grease, hair, soap scum, and other materials causing the blockage. The pressure is adjusted based on the type and severity of the obstruction.

  5. As the debris gets broken down, the powerful water flow flushes away the loosened particles through the drainage system. This ensures a thorough removal of obstructions and leaves the pipes clean and free-flowing.
    In advanced cases or where additional force is required, hydro-jetting may be employed. Hydro-jetting involves the use of a combination of high-pressure water and controlled force, offering enhanced capabilities in clearing even the most resilient blockages.

  6. Throughout the jet blasting process, monitoring tools, such as cameras, may be used to inspect the pipes in real-time. This helps ensure that the blockage is completely cleared and identifies any potential issues within the pipes.
    Safety measures are crucial during jet blasting. Operators wear protective gear, and precautions are taken to prevent injuries. Proper training is essential to ensure the safe and efficient execution of the process.

  7. After the jet blasting is complete, a post-inspection is often conducted to verify the success of the process. This ensures that the drainage system is clear of obstructions and is functioning optimally.
