A collapsed drain is serious, but recurring blockages do not prove collapse. Understand the clues and checks.
What collapse can look like
Broken or displaced pipes may trap solids and interrupt flow. In some cases a substantial defect allows surrounding ground to wash into a drain.
Do not diagnose from one symptom
Slow drainage and repeated obstructions can have much simpler explanations. A depression in the garden also has several possible causes.
Why inspection matters
A camera survey can show deformation, fracture, missing sections or displaced joints, subject to visibility. Sometimes the pipe first needs clearing before a reliable view is possible.
Choosing the repair
Local excavation, no-dig repair or replacement may be considered depending on extent, access and pipe condition. Ask for the evidence, location and expected outcome in writing.
Urgency
If there is sudden ground settlement, sewage overflow or a possible hazard near the house, restrict access and obtain prompt professional assessment.
