High-pressure water jetting for London drains

High-pressure water jetting uses water pumped at pressures between 1,500 and 4,000 psi to remove blockages and clean the full bore of the drain. Unlike drain rods, which punch through a blockage but leave residue on the pipe walls, jetting simultaneously clears the blockage and scours the internal pipe surface, restoring full flow capacity. This is the correct UK term for the technique sometimes referred to as hydro jetting in North American usage.

London's Victorian-era clay drainage — the majority installed between the 1860s and early 1900s — is particularly prone to grease and fat accumulation. Decades of cooking waste from London's dense terraced housing stock and commercial kitchens build up on rough clay pipe walls, eventually narrowing the bore to the point where blockages recur every few months. High-pressure water jetting is the only method that removes this build-up completely and restores full pipe capacity.

Our process

Inspect

We confirm the blockage location and assess the pipe condition. For London's older Victorian clay drainage, we check for cracks or displaced joints before selecting the correct jetting pressure to avoid causing damage.

Resolve

We jet the drain using the appropriate nozzle — rotating head for grease, penetrating nozzle for scale, or root-cutting head for tree root ingress common in London street trees. The engineer works until the post-jet flow test confirms full clearance.

Prevent

We advise on the blockage cause — often grease from London commercial kitchens or root ingress from Victorian-era street trees — and recommend a maintenance schedule to prevent recurrence.

High-Pressure Drain Jetting — frequently asked questions

Is high-pressure jetting safe for Victorian drains in London?

Yes, when carried out by an experienced engineer who assesses the pipe condition first. We adjust the operating pressure to suit the pipe type and condition. If there is any doubt, a CCTV survey before jetting is the safest approach.

Do you provide sewer drain cleaning across London?

Yes — sewer drain cleaning is one of our most-booked services. Our high-pressure jetting units clean lateral drains, shared sewer runs, and the section of pipe between your property and the public sewer connection. We use specialist nozzles for grease, scale, and root infiltration, and we provide before-and-after CCTV footage as standard for sewer drain cleaning jobs.
