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 Ebbw Vale 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 Ebbw Vale?
Drainage leak investigation in Ebbw Vale follows suspected escapes from waste pipes and drainage routes.
- The Works combines business, education, housing and leisure uses on the former steelworks site.
- For a premises enquiry in that setting, explain whether the affected drainage serves only your unit or passes through a managed shared area.
- The team can use the discharge pattern and accessible inspection points to plan suitable checks.
- The council directs public-sewer incidents to Welsh Water.
- The connection at your building needs its own responsibility check, particularly where the suspected section extends beyond the part of the premises you control.
How does ADI Leak Detection Ebbw Vale 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.

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?
Pipes serving more than one property, or serving a single property outside its boundary, are probably Welsh Water’s responsibility. Pipes serving only your property within its boundary are your responsibility.

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.
