A CCTV Drain Survey is a method used to inspect the condition of drainage systems using a small camera attached to a flexible rod. This camera is inserted into the drain, allowing professionals to view real-time footage of the interior. The survey helps identify blockages, cracks, or other issues without the need for invasive digging. These surveys are commonly used by plumbers and drainage specialists to assess problems in residential and commercial properties. The information gathered can guide necessary repairs and maintenance, ensuring that drainage systems function effectively and preventing future issues.
