Our East Bay Coverage Area

Check your bill for your provider.
Hillside Lots and Pressure
East Bay hills create large pressure differences. High pressure strains fixtures and heaters, and a regulator and gauge help.
Craftsman Bungalows, Cast Iron and Clay Laterals
Older homes often have galvanized supply, cast iron drains and clay laterals, and mature trees send roots toward old joints. A written inspection and a camera run before buying or renovating show what remains.
Faults and Seismic Safety
The Hayward and Calaveras faults run through the East Bay. Brace the heater, use flexible gas and water connectors and know where both shutoffs are.
