What cctv drain surveys involves
A CCTV drain survey records the inside condition of accessible drainage runs. It can help identify blockages, open joints, root intrusion, deformation or other visible defects, giving a clearer basis for repair decisions or a property purchase enquiry.
When it may help
- Recurring or unexplained blockages
- A property purchase or sale
- Suspected pipe damage
- Planning a repair or insurance enquiry
How it is assessed
A camera is introduced through a suitable access point and guided through the accessible pipework. The footage is reviewed with the route, pipe condition and any visible defects recorded in the survey findings.
What to expect
Before an engineer arrives
Let the engineer know the reason for the survey, any known drainage issues and the access points available. For a purchase, share any questions that need answering in the report.
Timing
Survey time varies with the number of drainage runs, access conditions and the extent of inspection needed. The expected scope should be agreed before the survey begins.
What affects the price
Price is affected by the size and layout of the system, access, the amount of footage and reporting required, and whether a blockage must be cleared before inspection.
Excavation and alternatives
A survey is non-invasive and uses existing access points where possible. If the survey identifies a fault, repair options can then be considered separately.
Common questions
What can a CCTV drain survey show?
It can show the accessible condition of a drainage run, including blockages, root intrusion, open joints, deformation and other visible defects.
Is a drain survey useful before buying a property?
It can provide additional information about accessible drainage that may not be visible during a standard property inspection.
What affects the scope of a survey?
Access points, the number of drainage runs, the length of pipework and the required report detail all affect the survey scope.
