What are the signs of a drainage fault?
A drain smell, slow or gurgling toilets and gullies, or sinking ground near a chamber can indicate a fault. ADI Leak Detection Throckley locates the cracked, collapsed or root damaged section and reports its position.
A drain fault is out of sight underground, so these signs are usually the first warning:
- A drain smell in the garden or in a downstairs room
- Gullies and toilets that empty slowly or gurgle
- Repeated blockages in the same run of pipe
- Ground sinking near an inspection chamber or a soil pipe
- Rats, which follow broken drains
Where do drainage faults occur in Throckley?
The team investigates suspected private drainage leaks at homes and local premises.
- Older terrace rows at The Leases and the documented industrial setting provide different access situations for such enquiries. Tell the advisor which drains appear involved, where the symptom is visible and whether a previous inspection identified a specific section.
- If plans exist, explain any later changes to the layout or occupied units. Responsibility for a shared line should be confirmed before private work is arranged, and another occupier may need to authorise access to a cover or service area.
- The person arranging the investigation should provide the available findings and identify what remains unresolved. The enquiry then concerns the actual drainage route at the Throckley property, rather than a conclusion drawn from its age or surrounding land use.
How does ADI Leak Detection Throckley find a drainage fault?
The engineer opens the inspection chambers, runs a CCTV camera along the drain and locates the defect with the camera's sonde. Once the position is found, the engineer explains it on site before any repair is discussed.
The inspection chambers reveal the drain layout when their covers are lifted, before the camera survey starts.
A CCTV drain camera records the condition of every joint, bend and connection as it travels through the pipe.
The camera sonde, tracked from the surface, gives the position and depth of the drain defect on the ground above.
Acoustic listening and water testing confirm whether a defect is actually losing water.
The drain condition report includes the survey video, still images and a plan of the pipe run.
What happens after a drainage fault is found?
The drain defect is located, marked and reported with the CCTV footage. Drain repairs and lining are carried out by a drainage contractor, working from the survey.
Every leak detection visit ends with a written report by the engineer who attended, with photographs and video, formatted for trace and access and escape of water insurance claims.
- The leak position marked on site and explained before you decide anything
- Photographs and video in the written report

What do people ask about drainage leak investigation?
Before a drainage investigation people ask how long it takes, how it differs from a CCTV survey, what happens with a shared drain and whether drains get unblocked.
How long does a drainage leak investigation visit take?
It depends on the property and how much of the system has to be tested, so the advisor gives you an estimate when you book.
Is a CCTV drain survey the same as leak detection?
A CCTV drain survey is the drainage form of leak detection. The camera shows the pipe condition and the sonde locates the defect, giving your repair contractor the information needed to plan the work.
Who is responsible for a shared drain?
Northumbrian Water maintains public sewers and most shared sewers. Owners maintain drains serving only their property within its boundary. Shared drains serving flats within a single boundary, private treatment systems and drainage that does not connect to a public sewer can remain private. Drainage for properties built after 2011 generally remains with the owner or developer; check responsibility with Northumbrian Water.
Does ADI Leak Detection unblock drains?
Clearing enough of a blockage to get the camera through is part of the survey. Full drain clearance, repair and lining is a drainage contractor’s work.
