It depends on the leak location. Leaks from external fittings, shutoff valves, or T&P relief valves can easily be repaired. However, if the internal steel tank itself has rusted through and cracked, full unit replacement is required.
First, turn off the cold water shutoff valve above the tank to stop incoming water flow. Next, shut off the power at your breaker box (for electric units) or turn the gas control dial to “OFF” (for gas units), then call a plumber.
Rumbling noises indicate heavy mineral sediment buildup at the bottom of the tank. As the burner or lower element heats water trapped beneath this sediment layer, steam bubbles pop loudly. Flushing the tank resolves this issue.
If your hot water runs out twice as fast as usual or stays lukewarm, one of your two heating elements (or its corresponding thermostat) has likely failed and requires multimeter testing and replacement.
"Quality doesn't cost, it pays. We treat every customer like family with reliable craftsmanship and with clear honest cost guidance."
