A blocked drain can be something of a nightmare for the British homeowner, as the blockage could literally be anywhere within the maze of underground drainage pipes. Rather than digging up half of the garden, you can contact a company that undertakes CCTV drain surveys in Leeds, and they can quickly pinpoint the blockage and carry out effective repairs.

Causes of Blocked Drains

There are many potential causes of a blocked drain, which include the following:

• Invasive Tree Roots – Tree roots can cause a sewer pipe collapse.
• Ground Subsidence – Common with new and old properties.
• Foreign Objects – Over time, foreign objects can become lodged and cause a partial or total blockage.
• Build Up of Food Waste – You are not advised to put food waste down the sink.  

The Benefits of CCTV Drain Inspections

The only way to find out what is causing the blockage is to send down a video camera, which gives the technician a close-up view of the inner pipes, and once the blockage has been located, the technician can make a recommendation on the best repair solution. Using CCTV eliminates the need for digging, which is very much hit and miss, and by pinpointing the blockage with video, you save both time and money.  

Pipe Relining

In some cases, the drainage system is very old, and often, the best way to repair damage is to reline the pipes. This can be carried out without having to excavate the pipe, by using an inflatable inner pipe sleeve, which cures after being put in place, and provides a new inner surface.
