Sediment buildup
Hard water minerals accumulate in the tank, reducing efficiency and causing rumbling noises.
Seismic strapping compliance
Older installations may lack proper strapping, which is required by California law to prevent tipping during earthquakes.
Expansion tank failure

The old unit is drained and disconnected, and the new unit is installed with seismic strapping at the upper and lower one-third points. An expansion tank is added if not present. The job typically takes 4–8 hours, and the plumber will schedule a final inspection to ensure code compliance.
