Is the failure isolated?
A visible crack identifies one failure, but the surrounding pipe still needs assessment. Ask whether other damage is visible after access is opened.
Will the new fittings suit the existing pipe?
The material and diameter determine compatible connections. Ask how any transition between materials will be made.
Has the same line failed before?
Share the location of previous repairs and any known freezing episode. Repeated repairs can help explain why a longer section is being considered.
What is the minimum sound connection point?
The new section needs suitable pipe to join onto. Ask the provider why the chosen end points are appropriate.
What is the difference in the written scope?
Compare the proposed repair length, access work and testing. Ask about the limits of each option rather than accepting a broad replacement recommendation without an explanation.
