A CCTV drain survey is an internal inspection of accessible drainage pipework using specialist camera equipment. The camera is introduced through a suitable access point and carefully guided along the drain while the engineer monitors the internal view. This can reveal trapped objects, waste deposits, root intrusion, cracks, displaced joints and collapsed sections of pipe. A survey is often recommended when a blockage repeatedly returns or the cause cannot be identified from the surface. The findings help determine whether the drain requires unblocking, high-pressure cleaning or repair work and allow the affected section to be targeted more accurately.

Consider arranging a CCTV inspection if the same drain repeatedly becomes blocked, several fixtures are draining slowly or wastewater is backing up without an obvious cause. Persistent smells, unexplained dampness near a drainage route and suspected pipe damage may also justify further investigation. A survey can support decisions before certain repairs or property work by providing more information about the condition of accessible pipework. However, not every straightforward blockage requires a camera survey. Contact Blockage Busters and explain the symptoms so our team can advise whether the drain should be inspected, unblocked or cleaned first.

A CCTV survey may reveal signs that a pipe has partially or fully collapsed, provided the camera can reach the affected section. The footage may show severe deformation, broken pipework, displaced material or a point beyond which the camera cannot travel. It can also identify other defects that produce similar symptoms, including root intrusion, displaced joints and substantial deposits. If the camera cannot pass through because the drain is completely obstructed, preliminary unblocking or further investigation may be required. Once the likely position and nature of the problem have been established, suitable drain repair options can be considered.

The camera requires enough space to travel through the pipe and capture a useful view of its internal condition. If a drain contains substantial standing waste, grease, silt or another complete obstruction, it may need to be unblocked or cleaned before an effective survey can be completed. Attempting to inspect through dirty water or heavy deposits may obscure defects and limit how much of the pipe can be examined. Our engineers can assess the condition of the drain and advise whether high-pressure water jetting or another cleaning method is required before continuing with the camera inspection.

Blockage Busters provides a range of services for problems discovered during CCTV drain surveys. Removable obstructions may be addressed through professional drain unblocking, while grease, silt and other stubborn deposits may require high-pressure water jetting. Limescale cleaning is available for suitable mineral deposits. If the inspection identifies cracks, displaced joints or damaged sections of pipework, drain repair or patch lining may be recommended. The appropriate solution depends on the location, severity and accessibility of the defect. For urgent problems involving wastewater backing up or overflowing, our emergency drainage service is available 24 hours a day.
