Drain Cleaning in South Whittier, CA
Help for clogged drains, slow drains and sewer line backups

South Whittier is an unincorporated community of about 56,000 residents just south of the City of Whittier. Its public sewer mains are maintained by Los Angeles County Public Works, while homeowners maintain their own laterals. Main line backups, kitchen grease clogs and toilet clogs in busy households are the drain problems people most often need help with here.
South Whittier is not part of the City of Whittier. It is an unincorporated community in Los Angeles County, with a 2020 census population of 56,415, located just south of the city. It is a dense, largely residential area of single-family homes and apartments, and most residents own their homes.
Because South Whittier is unincorporated, the public sewer system here is the county's responsibility. That is useful to know when a backup happens: if the blockage is in your lateral, you arrange the cleaning; if it is in the public main, the county handles it.
