CCTV Drain Surveys
See what is happening inside your drainage system before deciding on the next step. Pulse Drainage provides CCTV drain survey and investigation support across London & Hertfordshire.
What to expect
Find the problem without guessing.
A CCTV drain survey can help investigate recurring blockages, suspected damage or an issue that cannot be confirmed from the surface. The aim is to understand what is happening in the pipework and make the next decision clearer.

Investigation of recurring blockages
Identification of visible defects or obstructions
Drain tracing where appropriate
Survey findings to support the next drainage decision
Drain investigation
Use CCTV when you need to see more than the symptom at the surface.
A CCTV drain survey uses a camera to inspect accessible drainage pipework and give a clearer view of what is happening below ground. It can be useful when a blockage keeps returning, the cause of poor flow is uncertain, drainage routes need to be understood or a property decision would benefit from more information about the system.
The purpose of the survey is not simply to produce footage. It is to support a better drainage decision. Visible obstructions, build-up, displacement or other defects can help determine whether clearance, jetting, monitoring or another type of follow-up work is the sensible next step.

When a CCTV survey can be useful
Recurring blockages where the underlying cause has not been established
Pre-purchase or property-related drainage investigation
Understanding drain routes, connections or areas that need closer inspection
Supporting a decision before repair, maintenance or other planned work
Service questions
Useful things to know.
These answers are general guidance. The right approach depends on the drainage system and what is happening at the property.
When should I consider a CCTV drain survey?
CCTV is useful when the cause of a drainage problem is unclear, when a blockage repeatedly returns or when you need more information about the condition or route of the pipework.
Does a CCTV survey clear a blockage?
A survey is primarily an inspection. If access is obstructed, clearance may be needed before the camera can inspect the relevant section properly.
Can CCTV help before buying a property?
Drainage inspection can provide additional information about accessible pipework before a property decision, particularly where drainage condition is a concern.
What happens after the survey?
The findings should help determine the sensible next step, which may be no immediate work, further clearance, jetting, monitoring or another drainage service.
CCTV survey context
What CCTV drainage investigation can help reveal.

Camera-led inspection
A camera survey helps move the conversation from surface symptoms to what can actually be seen inside accessible pipework.

Drain routes and mapping
Understanding the route and connections of a drainage system can support investigation and planned work.

Property drainage decisions
Drainage inspection can provide useful context where pipe condition matters before a property or maintenance decision.
Understanding CCTV drain surveys
What a camera inspection can reveal and when it is worth using one.
A CCTV drain survey is most useful when you need better information before deciding what to do next. It can help investigate recurring blockages, uncertain drainage routes, visible signs of poor flow or concerns about accessible underground pipework.
Common causes
Reasons a CCTV drain inspection may be useful
The same blockage keeps returning
Repeated clearance can restore flow without explaining why the restriction keeps coming back. A camera inspection can help identify visible build-up, obstructions, displacement or other conditions that may be contributing to the pattern.
The cause cannot be confirmed from the surface
Bad smells, slow drainage and intermittent backing up do not always reveal where the problem sits. CCTV gives a direct view of accessible pipework so the next decision is based on more than the visible symptom.
You need to understand the drainage route
Drain tracing and camera investigation can be useful where connections, branches or the direction of the drainage are uncertain. That information can support maintenance, property work or a more targeted follow-up investigation.
A property decision needs more drainage information
A pre-purchase or condition-led survey can add information about accessible drainage before a property decision. It should be treated as evidence about what can be seen, not as a guarantee that every part of the system is defect-free.
Choosing the right method
What happens around a CCTV drain survey
The quality of the inspection depends on access, visibility and choosing the right point in the process to use the camera.
Establish access and symptoms
Before the camera is used, it helps to understand which drainage points are affected and where access is available. If the pipe is completely obstructed, some clearance may be needed before the relevant section can be inspected properly.
Inspect accessible pipework
The camera can be moved through accessible drainage to look for visible obstructions, build-up, displaced joints, damage, changes in pipe condition or other features that may help explain the symptoms being reported.
Use the findings to choose the next step
The value of the survey is in the decision that follows. The result may support clearance, jetting, monitoring, further investigation or repair planning depending on what is visible and how it relates to the original problem.
Property context
CCTV surveys can support more than one type of drainage decision
Recurring domestic problems
Useful when the same blockage or poor flow keeps returning and the cause has not been established.
Property purchase decisions
Can provide additional information about accessible drainage where pipe condition is part of the due-diligence process.
Landlords and managed property
Helps investigate repeated drainage complaints where repeated clearance has not explained the underlying issue.
Commercial sites
Can support maintenance and repair decisions where downtime, access and multiple drainage routes need to be considered.
More questions
Useful questions before choosing the next step.
Does a CCTV drain survey inspect every part of a drainage system?
No. A survey can only inspect pipework that is accessible to the camera and clear enough to see. Access, standing water, a complete obstruction or the layout of the system can limit what can be inspected from a particular point.
Is a CCTV survey useful if the drain is currently flowing?
Yes, if there is still a reason to investigate recurring symptoms, poor flow, suspected damage or the route of the drainage. The purpose is not limited to finding an active blockage; it is to provide useful visual information about accessible pipework.
