The specialty of the shop. Broken, bellied and root-blocked sewer laterals diagnosed and repaired.

Tankless water heater installation and servicing, plus repair and replacement of standard tanks.
Faucet installation and repair, toilet repair, and whole-house water filter installation.
Why homeowners call back
Anderson Sewer and Rooter is registered with the state as a sole ownership, and the license carries a workers’ compensation exemption because there are no employees. In plain English: there is one plumber, and he is the owner. Nobody hands your job to whoever is free that afternoon.
That shows up in the reviews. Customers from 2023 through 2026 name Sam personally — same plumber, same standard, three years apart.
Verify any of this yourself: search license #1132129 at cslb.ca.gov. It is a C-36 plumbing license, current and active, with a $25,000 contractor’s bond on file.
