Click your brand of water heater for the warranty validation page
The serial number of your water heater will be needed to validate the warranty and confirm the age of the heater. The serial number is located on the rating plate/sticker on the water heater. Please note that most GSW and John Wood water heater serial numbers will work on the AO Smith warranty validation page.
