After the repair
The new line is pressure tested, flushed and inspected where a permit is required. Then the trench is backfilled and compacted. Keep the final invoice and any inspection sign-off for resale, insurance and utility records.
Spot repair vs full replacement: what to ask
Ask how many joints or sections are failing, whether the pipe near the repair is sound, and what the cost per foot of full replacement would be. If the cost gap is small and the pipe is old, replacement is often the better long-term value.

Does the repair come with a warranty?
Ask for a written warranty on labor and materials before approving the work.
