A repair may remove one defect while leaving another restriction or poor pipe gradient. Compare current symptoms with the precise location of the earlier repair.
Before arranging disruptive work, separate what has been observed from what is only suspected. Ask whether one outlet is involved or whether several drain to the same point.
What else might cause it?
A returning blockage doesn't prove the original contractor caused damage. Drainage faults can overlap with surface-water problems, poor plumbing connections or unusual weather, so timing and location deserve attention.
Getting the right work done
A follow-up survey may show whether the repaired section is sound. Ask for a clear explanation of the problem, the proposed method and what evidence will show that the work was successful.
Before you agree to major work
Get the proposed work and its limits in writing. For costly repairs, ask for photographs or survey evidence locating the defect and consider a second quotation. Where the affected run may be shared or adopted, check ownership before arranging privately funded work.
