Overtime, water heaters corrode producing weak spots and small holes in the tank’s metal. These holes may be extremely small at first but will surely manifest into a problem that eventually will have to be resolved. To determine if your water heater tank has a leak, visually inspect the top, bottom and entire outer surface of the water heater tank for any signs of water. If a leak is discovered then the water heater unit will need to be replaced since there currently is no solution to repair water heater tanks.
Water heater tank leaks are a covered item under most manufacturer warranties as long as warranty terms and conditions have been met. Most manufacturers provide an option on their website to lookup warranty status information. Just write down the serial number and model number from the manufacturer’s sticker located on the water heater and then enter it into the online lookup screen.
Please be aware that over the last few years California established new water heater emission laws requiring water heater manufacturers to upgrade their product lines. If you have an older water heater model, you may be responsible for the cost to upgrade to a new compliant model. The cost difference to homeowners is approximately $100-$175; depending on water heater size and manufacturer. While OneStop Plumbers doesn’t charge customers a mark-up price on warranty upgrade orders, some plumbing companies may, so it is advisable to ask.
If the tank shows no signs of a water leak, then continue troubleshooting the source of water by next checking the water heater’s supply lines.
