Finding out the root cause of your problems is a simple process and that of sending a CCTV down your drain(s) to carry out a drain survey is the most direct method. Here we will discuss what findings your surveyor will obtain from viewing the footage and how each individual finding can be used to diagnose and thereby recommend solutions to your problems.
Root Intrusion
Tree and shrub roots can find their way into pipes through hairline cracks or poor jointing. Once inside, the root mass spreads to fill the pipe. A CCTV drain survey can identify where the root intrusion has taken place and record the exact location. Root cutting can then clear the blockage. Depending on the severity of the root penetration, a patch or pipe lining may also be required to repair any damage to the surrounding pipe walls.
Pipe Deformation
Pipe Deformation: As mentioned earlier Pipe Deformation can cause serious problems with drains. A pipe that has been buckled, flattened or even collapsed is easily identified on a CCTV drain survey. The amount of deformation is noted and if partial a relining solution could be appropriate however if the pipe has collapsed completely then excavation of the pipe would be required to repair.
Joint Displacement
Over time pipes can move which can cause the joints between sections of pipe to become displaced. These displaced joints can cause leaks from within the system as well as slow infiltration of groundwater into the system. A CCTV Drain Survey Coventry property owners carry out will often discover joint displacement as the root cause of a number of problems with a drain.

Build-Up Narrowing the Bore
Grease, scale and other sediment build-up on the internal surface of pipes. This build-up will progressively narrow the bore of the pipe. On inspection by a CCTV Drain Survey Coventry surveyor, a reduced bore is revealed with a rough or layered surface on the internal surface of the pipe. It is then determined if a simple jetting of the drain is required to clear the blockage or if further treatment is required to clear hard build-ups.
Gradient Faults
Drains are laid at certain angles to allow for the free flow of water. If a pipe is laid at the wrong gradient water will not drain properly and will pool within the pipe. maintenance of which pipes as a gradient fault on a shared sewer would need to be dealt with by the main responsibility party as opposed to a private lateral.
So, in summary, each finding will be logged along with an assessment of the cause and recommended repair to provide a clear answer and course of action before incurring large repair costs.
