Drains in big cities like London have a much higher chance of getting blocked when compared to other cities. Drains can get clogged due a number of reasons. A root of a tree might block a drain, debris fallen into the drain due to construction work can also sometimes block a drain. Moreover, drains like any other civic amenity can wear out with the passage of time.
Therefore, one of the first steps before cleaning a blocked drain is to identify the cause of the blockage. It has been noticed that on a lot of occasions, people use harmful chemicals to clean drains that have been blocked. These chemicals are known to damage the drains more than they clean them.
One of the best ways to find out the cause of a blocked drain is to have a look at it. Since it can be very difficult to physically enter drains and find the problem, hiring a professional drain management company can solve your problems. Professional drain management companies based in London use the benefits of CCTV. CCTV can help to look at the insides of a drain and can be quite useful in finding the root cause of the blockage.
A CCTV survey is conducted by attaching a small camera on the head of a long flexible rod which is then introduced into the drain. This provides in-depth information about the clogged drain and enables the professional drain cleaning company to take the necessary measures to clean it.
