Drain investigation

A closer look inside the drainage run

A camera survey may help examine accessible pipework and record visible conditions. The right survey scope and deliverables depend on why the inspection is needed.

Reasons to ask about a survey

  • A blockage or symptom keeps returning.
  • There is a suspected defect or damaged section.
  • Evidence is needed before planned work.
  • A property-related inspection is being considered.

Be clear about the required output

A recording, written report, map or document for a lender or insurer must never be assumed. Explain the purpose of the survey so the required deliverable can be confirmed before work is agreed.

If damage is suspected, read the drain repairs guide.

Do not wait for a complete failure

Warning signs deserve an answer.

Slow flow, gurgling, smells or repeat blockages can point to a developing drainage problem. Ask about a CCTV inspection before the situation becomes more disruptive.
