We provide sonde drain tracing across Stockport, Manchester and the surrounding areas, to locate pipe runs, work out the direction of flow and pinpoint blockages, defects and inspection chambers without unnecessary digging.
It's often called sonar drain tracing. The method we use is sonde tracing: a small transmitter goes into the pipe, on a rod or on the CCTV camera head, and we follow its signal from the surface with a locator.
When Drain Tracing Helps
- Locating hidden or buried drain runs
- Finding lost or covered inspection chambers
- Working out the direction of flow
- Pinpointing blockages or defects
- Planning excavations and repairs
- Pre-purchase investigations
- Confirming drain layouts before building work
- Checking drains before a new driveway or patio
Why Drains Need Tracing
Drains don't always run where you'd expect. On older homes and altered buildings across Stockport and Manchester, pipes often take unusual routes or disappear under extensions, driveways, patios and gardens.
Tracing tells us where the line runs, so CCTV surveys, patch repairs and excavations can be done accurately and with less disruption. It saves money by cutting out guesswork and showing the best place to investigate.
Signs you may have a buried manhole: you have a gully or soil pipe but no manhole anywhere nearby; your neighbour has a manhole on the shared boundary but you don't; old plans or deeds show a chamber where there's now paving; or a blockage can only be reached from a long way off. Buying a house? A drain plan is useful if you're unsure what you're taking on.
How We Trace a Drain
-
We get into the drain
We access the system through a chamber, gully or soil vent pipe, wherever is most suitable.
-
We follow the signal
We send the sonde or CCTV camera down the pipe and track its signal from above ground.
-
We mark the route
We mark out the route and any likely chamber locations, defects or problem areas, and explain what we've found.
Drain Tracing Prices
Drain tracing visit
Tracing a drain run, finding chambers and marking the route. Includes drain mapping.
Drain mapping
Included with every drain tracing visit, to show how the drains run across the property.
CCTV drain survey
Camera inspection, no report. £220 + VAT for one drain with a written report, and home buyer surveys from £320 + VAT.
Pricing depends on access, site conditions and whether tracing is done alongside unblocking or a CCTV survey. If tracing is part of a bigger investigation, we'll advise on the most cost-effective option when you book. A written CCTV report is £80 + VAT. See our pricing and terms.
Tracing and CCTV Together
In many cases tracing is most useful alongside a CCTV drain survey. The camera shows the condition of the drain, and the sonde in the camera head shows exactly where each section sits underground.
That's especially helpful when we're looking for cracked sections, root ingress, collapses or hidden chambers, or deciding the best place to dig. Read about replacing broken manhole covers once a chamber has been found.

Drain Tracing FAQs
How much does drain tracing cost?
A drain tracing visit is from £250 + VAT and includes drain mapping. The price depends on access, site conditions and whether we're tracing alongside unblocking or a CCTV survey. We'll advise on the most cost-effective option when you book.
Is it sonar or sonde drain tracing?
People often search for sonar drain tracing, but the method we use is sonde tracing. A small transmitter, the sonde, goes into the pipe and we follow its signal from the surface with a locator.
Can you find a buried manhole?
Often, yes. By tracing the line from a gully or another chamber, we can usually pinpoint where a buried or covered manhole sits, so it can be uncovered without digging up the whole garden.
Can drain tracing be combined with a CCTV survey?
Yes, and it's often the most useful option. The camera shows the condition of the pipe while the sonde shows exactly where that section is underground.
Do I need my drains traced before building an extension?
It's a good idea. Knowing where the drains run helps you plan foundations and avoid surprises. If you're building near or over a public sewer, you may also need permission from United Utilities.
Do you trace drains for businesses?
Yes. We trace drains for homes, rental properties, shops and business premises across Stockport and Greater Manchester.
