High-Pressure Water Jetting (HPWJ) Services

When pipes, drains, or industrial lines become blocked with grease, scale, or debris, traditional cleaning methods aren’t always enough. That’s when High-Pressure Water Jetting (HPWJ) comes into its own. Using advanced water jetting technology, we deliver powerful cleaning that restores your system to peak performance — quickly, safely, and with minimal disruption.

At First Choice Drainage Solutions, we provide professional HPWJ services across London, Essex, Kent, Surrey, and Hertfordshire. Whether it’s a domestic drain blockage, a heavily used commercial kitchen system, or large-diameter industrial pipework, our engineers have the equipment and expertise to get the job done right.

What Is High-Pressure Water Jetting?

HPWJ is a proven, environmentally friendly method of drain and pipe cleaning. By directing pressurised water through specialist jet heads, we can:

• Break down fats, oils, and grease (FOG) – common in kitchen and catering environments.

• Remove mineral scale – restoring full flow in hard water areas.

• Dislodge root intrusions – clearing roots without excavation.

• Flush out silt and sediment – preventing standing water and recurring blockages.

• Clean interceptors and gullies – keeping surface drainage systems clear.

Because the pressure is adjustable, HPWJ is effective across a wide range of applications — from delicate domestic pipework to heavy-duty industrial cleaning.

Benefits of HPWJ

• Thorough cleaning – removes deposits that rods and plungers can’t reach.

• Non-invasive – clears blockages without digging or dismantling pipework.

• Safe for pipes – targeted jet heads clean without causing damage.

• Fast and efficient – blockages cleared in a fraction of the time of manual methods.

• Versatile – suitable for reactive unblocking, preventative maintenance, and post-clean inspections.

• Eco-friendly – uses only water, avoiding harsh chemicals.

Where HPWJ Is Used

Our HPWJ services support a wide range of clients and systems, including:

• Domestic drains – clearing sinks, toilets, and outdoor drainage.

• Commercial kitchens – removing grease build-up from busy catering facilities.

• Car parks and forecourts – cleaning interceptors and gullies clogged with oil and sediment.

• Industrial facilities – flushing large pipe networks to maintain operational efficiency.

• Municipal drainage systems – supporting councils with gully and sewer cleaning.

No matter the size or type of system, HPWJ provides a powerful and reliable cleaning solution.

Our Process

1. Site Assessment
   We evaluate the blockage or cleaning requirement and determine the best jetting approach.

2. Jetting Operation
   Using flexible hose systems and pressure-adjustable jet heads, we flush through the affected pipework.

3. Waste Removal
   Dislodged debris, grease, and silt are cleared safely from the system.

4. Inspection
   Where needed, a CCTV survey is carried out to confirm the system is fully clean and free of defects.

5. Reporting & Advice
   We provide recommendations for ongoing maintenance to reduce future issues.
