How long is the A.O. Smith warranty?
Term varies by model and runs from installation; registering is voluntary and does not change it (US).
This is a typical figure, not a guarantee — the term can vary by product line and by country (UK and US terms for the same brand often differ). Always check the paperwork that came with your specific appliance.
