Is the water hard in Sunnyvale?

the South Bay's water is moderately hard — enough to scale water heaters and fixtures over time — so periodic flushing keeps them running efficiently.

Should I repair or replace my water heater?

Repair small issues on a newer unit; replace if it's leaking from the tank or over about 10 years old, since failures and flooding become likely.

Does my water heater need earthquake strapping in California?

Yes — California requires water heaters to be strapped and fitted with flexible connectors so a quake can't topple the tank or shear the gas and water lines.

Is a tankless water heater worth it in California?

Often yes — tankless units save space and run efficiently, but California's hard water scales them, so periodic descaling (and a softener) keeps them working.
