Describe the post-work behavior
Note the first occurrence, affected fixtures, weather, and whether the issue is intermittent. Stop adding water if an overflow is developing. Keep the original scope, final inspection video, warranty, and any change orders together for the provider’s review.
Ask for a comparison inspection
The useful question is how the current condition compares with the recorded finished job. Ask the technician to inspect accessible connections, liner endpoints, and unrepaired sections as well as the liner itself. Request copies of the new findings and an explanation of any area they could not reach.
Keep diagnosis separate from blame
If a defect is identified, ask how it relates to the contracted work and written warranty. Have any corrective scope and costs explained before authorization. Avoid assuming that a second company’s verbal opinion alone resolves responsibility; a documented condition is a better starting point.
Your next-step checklist
- Collect the scope, warranty, and final video
- Record exactly when and where backups occur
- Compare current footage with installation footage
Discuss the next step for your property
For a Philadelphia service enquiry, call (267) 740-0245. Describe the symptoms, the address, and any inspection findings. Ask about CIPP pipe lining and confirm provider availability before arranging work.
