What is high-pressure drain jetting?

High-pressure drain jetting (also called hydro jetting or water jetting) uses a powerful pump to force water through a flexible hose at pressures of up to 4,000 PSI. The jet simultaneously cuts through blockages and scours the pipe walls clean, removing grease, scale, roots and debris.

How much does drain jetting cost?

Residential drain jetting typically costs between £100 and £300 depending on the severity of the blockage and pipe length. The engineer will quote a fixed price before starting. Using Blocked Drain Quotes to find a jetting engineer is completely free.

Can jetting clear tree roots?

Yes. High-pressure jetting with a root-cutting nozzle can cut through and flush away tree roots that have entered the drain. However, roots will regrow unless the structural defect allowing entry is repaired. After root removal, a CCTV survey is recommended to assess the damage.

Q: Is drain jetting better than rodding?

For most blockages, yes. Rodding (drain rods) can break up a blockage but often pushes debris further down the pipe and leaves residue on pipe walls, leading to faster re-blocking. Jetting fully clears the blockage and cleans the pipe walls, providing a more thorough and longer-lasting result.

Q: Will jetting damage my pipes?

No — when carried out by a trained engineer at the correct pressure for your pipe material, jetting is safe for all standard residential drainage including clay, plastic, cast iron and concrete pipes. Your engineer will assess the pipe type and condition before starting.

Jetting uses water at up to 4,000 PSI to blast through blockages and scour pipes clean. Faster, more thorough, and longer-lasting than rodding. Get a free quote today.

Why choose jetting

Jetting vs rodding — which is better?

High-Pressure Jetting

Recommended

Completely clears blockage — not just punches through it
Scours pipe walls clean, removing grease and scale
Removes root ingress with a root-cutting nozzle
Longer-lasting result — fewer repeat call-outs
Effective on fat, grease, scale, roots and compacted debris

Drain Rodding

Basic method

Often pushes debris further down, not fully clearing it
Does not clean pipe walls — grease and scale remain
Cannot remove root ingress effectively
Lower upfront cost for very minor blockages
Higher chance of re-blocking — more repeat call-outs needed

When is drain jetting the right solution?

Jetting is the professional standard for most drainage blockages. While a plunger is fine for a minor sink blockage, the following situations nearly always require jetting to resolve properly.

Stubborn blockages that rodding or chemicals have not cleared
Recurring blockages that keep coming back within weeks
Fat and grease build-up in kitchen or commercial drains
Tree root intrusion causing partial or full obstruction
Blocked outside drains and manhole chambers
Preventative maintenance on older drains before problems start
