Drain Jetting: how Blocked Up handles it
Rods push a blockage along. Jetting removes it. High-pressure water jetting scours the full bore of the pipe, cutting through fat, grease, scale, silt and even root growth, and flushes it all out to the sewer.
Blocked Up Drainage carries jetting equipment on the van, so it is available on emergency call-outs as well as planned cleans. It is also the right first step before a CCTV survey, because a clean pipe gives a clear picture.
Problems this solves
- Fat and grease build-up from kitchens
- Scale in older pipework
- Silt after flooding or heavy rain
- Root ingress in clay drains
- Drains that block again weeks after rodding
- Pre-survey cleaning
Why call Blocked Up
- Cleans the whole pipe, not just the blockage
- Safe for clay, plastic and cast-iron drains when done properly
- On the van for emergencies
