High-Pressure Drain Jetting In Derby

Jetting is the right tool when a drain keeps blocking, runs slowly after it has been rodded, or has a build-up of fat from a kitchen or takeaway. We usually follow a jet with a camera check, so you can see the pipe is clean and whether a defect — a displaced joint or a root entry point — is causing the build-up.

In Derby the public sewers belong to Severn Trent Water. If the problem is in a shared or lateral pipe it's normally theirs to clear — call Severn Trent on 0800 783 4444. Anything inside your boundary serving only your property is yours, and that's where we come in.

Severn Trent is clear that every food service business is legally responsible for keeping fat, oil and grease out of the public sewer. For a Derby takeaway, café, pub or restaurant, that responsibility starts at the kitchen sink. Warm fat cools in the pipe, coats the walls and catches food scraps, and the drain slowly narrows until one busy evening it stops. Rods can punch a hole through that build-up. Jetting scours the pipe back to its full width, which is why we recommend it for commercial kitchens and for any drain that blocks again within weeks.

Surface water drains need attention too. Derby's flood risk study explains that since 1980, new surface water sewers have been designed to cope with a storm that has a 3.3% chance of happening in any year. Until recently that standard didn't apply to smaller private systems. Silt in a private channel drain, yard gully or soakaway eats into capacity that may never have been generous. Jetting clears it out.

Jetting is also how we prepare a pipe for a camera survey or relining, because neither works in a dirty drain. We price jetting once we know the number of runs and the access.
