What we offer
When the blockage keeps coming back, you need a diagnosis
Some drainage problems do not respond to a quick clear. The same toilet blocks every three weeks. A persistent damp patch on a downstairs wall. Sewage smells that come and go. These symptoms point to an underlying fault that needs identifying before it can be fixed - which is what drainage fault finding is for.
Call2Drain runs a CCTV-equipped diagnostic vehicle for every fault finding visit. Crawler camera through every accessible run, sonde to locate buried pipework from above ground, acoustic listening equipment for leaks under floors, and dye testing to confirm cross-connections.
You receive a written summary explaining what was found, where it is located, the WRc severity rating, and what the right next step looks like - whether that is a clean, a patch repair, a full reline or excavation.
Evidence, not guesswork
Diagnostics in action
We find the cause on the screen, not by guesswork
A recurring blockage, a damp patch or an intermittent smell almost always has a single underlying cause hidden inside the pipework. Our diagnostic vehicle puts a high-resolution crawler camera through every accessible run and shows the defect on the monitor in real time — a cracked joint, a partial collapse, root ingress or a wrong connection.
Each Kent, Surrey, Sussex, Essex & London fault-finding visit pairs that footage with sonde tracing to pinpoint the exact location and depth from above ground, plus dye testing and acoustic detection where leaks are suspected under floors. You receive a plain-English written summary with the WRc severity rating and the right next step.
- Live CCTV footage of the defect, recorded for your report
- Sonde location of buried pipework — no needless digging
- Acoustic and dye testing for hidden leaks and cross-connections
- Fixed-price diagnostic fee agreed before we attend

FAQs
Common questions
How do you find a pipe underground?
A sonde transmitter on the camera head sends a signal to a receiver on the surface, letting us pinpoint the exact location and depth from above ground.
Can you find a leak under a concrete floor?
Yes. Acoustic listening equipment can often locate leaks under floors and hard surfaces without breaking through.
How long does fault finding take?
Most domestic fault finding visits take 90 minutes to 3 hours on site, depending on access and the complexity of the symptoms.
Do you offer fixed prices?
Yes. The diagnostic visit is a fixed fee agreed up front. Any repair work needed afterwards is quoted separately.
