Drains need to run smoothly. If there is any kind of blockage, you will start to experience some unpleasant incidents with overflowing toilets and wastewater coming back into the house. This needs to be avoided at all costs, and the use of a CCTV Drain Surveys London based operation such as https://www.drainpower.co.uk/drainage-services/cctv-drain-surveys/cctv-drain-surveys-london/ can be beneficial.
It’s not always easy to tell where the drain’s blockage occurs. In the past, the only way to find this out was to dig down into where the drain pipe was located. This was not an exact science and was almost guesswork. The interruption to the street and public life was annoying and disruptive. Also, if the drain workers got the wrong spot or they needed more exploratory work, then even more disruption was on the cards.
The creation of the CCTV camera was a real game-changer for the industry. It now meant that rather than digging up the road, all that needed to be done was the insertion of the camera down the drain pipe. This camera was small enough to see all the way to where the blockage was. As the camera gives measured metered readings, the operatives now know where they have to dig, how far down the pipe the blockage is and what the nature of the clog was caused by. In some cases, the direction of high-powered water blasts can clear the clog.
