回複：下水管子被樹根鑽了，臨街管口有OFFSET，求處理經驗

Repipe work fine if done right by reputable contractor. if it shrinks then the root still may come inside the annular space over time. Ask Repipe contractor how long it its longest repipe sewer work.

check your township rule to decide who "own" that offset. Each town may have different policy.
