Drain Cleaning in California
A plumber clears a clogged drain with a drain cable (snake) sized to the pipe, and uses a camera or hydro jetting when a clog keeps coming back. One slow fixture is usually a local clog; several slow fixtures at once point to the main line.

What drives drain cleaning 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.
Pre-war homes in Los Angeles, San Francisco and Oakland often have galvanized supply lines and cast-iron or clay drains. Slab-on-grade construction is common in Southern California and the Central Valley, while raised foundations are typical in older coastal neighborhoods.
