Seismic Strapping Requirements
California law requires water heaters to be braced at the upper and lower one-third points to resist earthquake displacement, adding labor and material costs.
Expansion Tank Installation
On closed plumbing systems, an expansion tank is required by code to prevent pressure buildup, which may not be present in older Sunnyvale homes.
Gas Line Upgrades for Tankless Units
Tankless water heaters often need a larger gas line ($375–$1,250) to handle higher BTU demands, especially in homes built in 1975 with original piping.
What to Expect During Installation
A licensed plumber will first obtain a permit from the City of Sunnyvale. The job includes removing the old unit, installing seismic straps, adding an expansion tank if needed, and connecting gas and water lines. For tankless units, a gas line upgrade may be required. Final inspection by the city ensures code compliance.
