A new homebuyer needs to decide whether to maintain or replace long sewer sags (bellies) under a deck/garage, risking costly emergency excavation.

No software exists to model long-term trade-offs between recurring hydrojetting and upfront replacement, or to predict failure risk given dirt/debris conditions under structures.
