    7th February 2025

    Blocked drains can be a nightmare, causing bad smells, slow drainage, and even flooding. One of the most effective ways to clear stubborn blockages is drain jetting. But what is drain jetting, and how does it work? In this guide, we’ll explain everything you need to know about this powerful drainage solution.

    What is Drain Jetting?

    Drain jetting is a professional method of cleaning and unblocking drains using high-pressure water jets. It blasts away debris, grease, tree roots, and other obstructions that can clog your pipes. This technique is widely used for both domestic and commercial drainage systems due to its efficiency and long-lasting results.

    Unlike traditional drain rods, which only break up blockages, jetting fully cleans the inside of pipes. This helps prevent future problems by removing built-up deposits before they cause further issues.

    How Does Drain Jetting Work?

    The process involves using a specialised jetting machine that pumps water at high pressure (often up to 4000 PSI) through a flexible hose. This hose is inserted into the blocked drain, and the pressurised water scours the pipe’s interior, dislodging debris and flushing it away.

    Here’s a step-by-step look at how drain jetting works:

    1. Inspection – A drainage specialist may first inspect the drain using CCTV cameras to locate the blockage.
    2. Insertion of the Jetting Hose – A high-pressure hose is fed into the drain, with a nozzle designed to break down different types of blockages.
    3. High-Pressure Water Jetting – Water is released at intense pressure, cutting through grease, scale, silt, and even tree roots.
    4. Flushing the Drain – The loosened debris is then flushed out, leaving the pipe clean and free-flowing.

    What Can Drain Jetting Remove?

    • Fat, oil, and grease build-up
    • Tree roots intruding into pipes
    • Silt and mud deposits
    • Soap scum and hair blockages
    • Food waste and organic debris
    • Limescale and mineral deposits

    Benefits of Drain Jetting

    1. Highly Effective

    Drain jetting is much more powerful than traditional drain rods, ensuring a thorough clean.

    2. Prevents Future Blockages

    Because it clears debris along the entire pipe, it reduces the chance of another blockage forming soon after.

    3. Safe for Pipes

    Unlike harsh chemical drain cleaners, jetting won’t corrode or damage your pipes.

    4. Eco-Friendly

    Since it only uses water (at high pressure), it’s an environmentally friendly way to maintain your drainage system.

    5. Fast and Non-Invasive

    There’s no need for digging or disruptive work—drain jetting quickly clears blockages with minimal fuss.

    When Should You Use Drain Jetting?

    If you’re experiencing:

    • Slow-draining sinks or bathtubs
    • Gurgling sounds from your drains
    • Bad odours coming from pipes
    • Recurring drain blockages

    Then it might be time for a professional drain jetting service.

    Very pleased with service provided by Cotswold Drainage, Luke did a great job. Would certainly recommend them, very efficient. Arrived on site when promised and solved the problem, can't ask for more than that.
    - Phil Timms
    I’d happily use Cotswold Drainage again - the engineer arrived and within a couple of minutes had not only identified the problem but cleared the blockage. He then went on to give everything a good hose down and then did a camera inspection to make sure there were no more issues further down the drain. Highly recommended.
