A water heater is one of the most essential systems in your home or business — and when it fails, it can cause major inconvenience. Knowing what signs to watch for can help you catch problems early and avoid costly damage. Common warning signs include:

-Heating element (electric) or burner failure (gas) — when your water only gets lukewarm or cold, a reset won’t help; a part replacement may be needed if the tank is still in good condition.

-Thermostat control issues — water that’s too hot, too cold, or constantly fluctuating often indicates a faulty thermostat.
