What drives sewer line repair calls in California
Sewer lateral failure
When: Winter rain and mature street trees. What fails: Roots and cracks in older laterals cause backups. What to do: A camera inspection is often required or recommended when buying an older home; some cities require lateral inspection at sale.
Winter storms: Heavy rain tests sewer laterals and storm drains; many older laterals in coastal cities are clay and let in roots and groundwater.
Dry season: Long dry months shrink some soils, and irrigation systems, backflow devices and outdoor lines get heavy use.
