Why High-Pressure Jetting Works

High-pressure water jetting (HPWJ) is the most effective and environmentally friendly method for clearing and cleaning drainage systems. Using controlled water pressure, jetting can cut through grease, silt, and roots while washing away debris, leaving pipes clean and fully restored — all without harsh chemicals or costly excavation.

At Clearmasters, we use state-of-the-art jet vac units capable of delivering up to 4,000 PSI, allowing us to handle everything from domestic drains to large-diameter sewers. Our skilled engineers tailor the pressure, nozzle type, and flow rate to your system, ensuring safe, precise, and effective cleaning every time.

Applications of High-Pressure Jetting

  • Blocked Drains & Sewers – Quickly clears obstructions caused by grease, silt, or foreign objects.
  • Grease & Fat Removal – Ideal for kitchens, restaurants, and food production facilities.
  • Root Cutting & Scale Removal – Restores flow and prevents structural pipe damage.
  • Pre- & Post-CCTV Survey Cleaning – Ensures clear visibility for accurate inspection results.
  • Preventative Maintenance – Keeps commercial and public drainage networks free-flowing year-round.

When Do You Need High-Pressure Jetting?

Jetting is recommended whenever your drainage system shows signs of restriction, slow flow, or repeat blockages. It’s also an essential part of ongoing maintenance for commercial or high-usage sites.

  • Slow draining sinks, toilets, or surface drains that keep backing up.
  • Recurring blockages that chemical cleaners or rods can’t resolve.
  • Grease or fat build-up in kitchen or restaurant drainage systems.
  • Root ingress or scale causing partial blockages in pipes or sewers.
  • Scheduled maintenance to prevent disruption in commercial and municipal networks.

Our 24/7 response team is fully equipped to handle emergency jetting and routine maintenance across Surrey, Sussex, Kent, Hampshire, and London — ensuring your system stays clean and compliant all year round.

Benefits of Professional Jetting

Regular jetting prevents costly drainage problems and improves the overall performance of your system. Whether you’re managing a single property or a full drainage network, professional jetting offers long-term reliability and peace of mind.

  • Restores Full Flow – Removes all traces of debris, grease, and roots.
  • Prevents Blockages – Stops build-up before it causes flooding or overflows.
  • Non-Invasive Cleaning – No excavation, no chemicals, no disruption.
  • Environmentally Friendly – Uses clean water under pressure — safe and sustainable.
  • Extends System Lifespan – Reduces wear and tear on pipework and infrastructure.

Jetting vs Traditional Drain Cleaning

Traditional drain cleaning methods, such as drain rods or chemical cleaners, can be effective for minor blockages — but they often provide only a temporary fix. In contrast, high-pressure water jetting (HPWJ) delivers a deep, long-lasting clean by completely removing build-up along the entire pipe length.

Traditional Cleaning

  • ✔ Suitable for small domestic blockages
  • ✘ Limited reach and cleaning depth
  • ✘ Risk of pipe damage with excessive force
  • ✘ Chemical methods can harm the environment
  • ✘ Usually provides only short-term relief

High-Pressure Jetting

  • ✔ Clears full pipe length, not just the blockage
  • ✔ Safe for most pipe materials with no harsh chemicals
  • ✔ Removes grease, roots, and scale completely
  • ✔ Prevents repeat blockages and extends system life
  • ✔ Fast, efficient, and environmentally friendly

In short: jetting isn’t just about clearing drains — it’s about restoring them. Whether for a one-off blockage or a planned maintenance programme, Clearmasters’ jetting services deliver the most thorough, reliable clean available.

Our Jetting Process

Clearmasters follow a structured, safety-led approach for all jetting works — ensuring efficiency, compliance, and minimal disruption.

1. Site Assessment

We assess drain layout, size, and material to select the right pressure and jetting nozzle for safe cleaning.

High-pressure water is delivered through the pipework to cut through blockages, grease, and scale build-up.

3. Waste Removal

Jet vac units collect loosened debris and waste for safe, compliant disposal at licensed facilities.
