What is a CCTV Drain Survey?

What is a CCTV Drain Survey?

Suppose you have a smelly sink, or a blocked toilet. A quick call to your Drainflow drain clearance specialist would normally ensure a quick resolution to the problem. But not always. Drains are complex systems and sometimes it’s necessary to investigate deep in the drainage system in order to discover the source of the blockage. It’s in these circumstances that we use a CCTV drain survey.


Yes, But What is a CCTV Drain Survey?

It’s a remote controlled closed circuit camera which is sent into the drainage system to find the blockage. The CCTV camera, or ‘crawler’, provides 360° imagery of the drain’s interior which is relayed to the surface where it is analysed by a Drainflow engineer. This ‘real time’ data allows us to both pinpoint the location of the blockage, and ascertain the nature of it.

CCTV Drain Surveys Usually Save Us From Digging

If it’s pipe damage that is causing the problem, we can use the CCTV camera as a repair vehicle. The ‘crawler’ is sent down the drain to the problem area. It’s used to place a patch liner over the damaged pipe. The liner is attached to a tube which is then inflated to bond the two surfaces. Once the bonding agent has dried, the tube is deflated, leaving the pipework restored to functionality.

What is a CCTV Drain Survey For Apart From Repairs?

CCTV drain surveys are used to check the condition of a drainage system prior to buying or selling a house. The diagnostics provide information about damaged pipes, but also give warning of potential problems that can be dealt with early. Repairs are far cheaper, as a result of a drain survey report, because the exact location requiring repair, or replacement is known.

Even if your drains are working perfectly well, it’s worth checking them out regularly. In the same way that a car service maintains the performance of your vehicle, a CCTV drain survey will ensure that your ahead of the curve should repairs or remediation be necessary. The frequency is dependent upon the age and condition of your pipes, but your Drainflow expert can offer guidance on this.

Will a Survey Disrupt the Household?

In the majority of cases there’s no disruption. You’ll be able to continue using your water supply whilst Drainflow engineers get on with the survey. The major benefit, however is that we’re able to manage most drainage repairs without the need to excavate. Where we do have to dig, the fact that we have a precise location limits the activity required.
