Plumbing in San Anselmo
San Anselmo Creek runs right through the middle of town, and downtown has flooded hard more than once, so backups and sewer overflow prevention matter here. A lot of the housing is early-1900s Craftsman and cottage stock with original galvanized pipe and old clay sewer laterals. The town is part of the Ross Valley Sanitary District, which requires a lateral inspection when a home is sold.
For homes in the flat blocks near San Anselmo Creek, we install backwater valves and sump pumps to keep storm backups out of the house.
Neighborhoods we cover: The Hub, San Anselmo Avenue, Red Hill, Sleepy Hollow, Seminary.
ZIP codes: 94960.
