A drainage investigation uses a CCTV camera to find out why a drain problem keeps happening. Unlike a routine survey, it has a narrow focus on your symptoms. The plumber traces the fault to its source.
This helps when blockages keep coming back, damp patches have no clear cause, smells linger or drains run slow. It also helps when standard unblocking has not worked. Push-rod and crawler cameras with tilting heads give a close view inside the pipes.
The investigation maps your drain layout and finds defects. As a result, you get clear proof of the cause. You receive a written report with footage, marked-up images and advice. The report can also help with insurance claims or disputes with neighbours over shared drains. Our guide explains what a CCTV drain survey tells home buyers.
The work for a drainage investigation depends on the system. A cause that is found quickly is simpler, whereas a hidden fault may need careful tracing. Request a quote online and describe the problem; the plumber will discuss the job with you.
