Water Heater Is Leaking — What Should You Do?
Control active water when safe, identify where the leak appears, and avoid assuming every puddle means the tank itself failed.
Emergency plumbing guide
Look at where the water appears
Use the visible pattern to decide what you can safely control now and what information will help identify the next plumbing step.
- Check the tank body, top connections, relief-valve area, nearby piping, and base of the unit without touching unsafe components.
- Water can come from a supply connection or valve even when it collects beneath the tank.
- The visible location helps determine whether the problem centers on the heater or connected plumbing.
If the situation changes while you are checking the area, treat the new symptom as important information and avoid continuing to use plumbing that is actively leaking, overflowing, or returning wastewater.

Control active water
The goal is to reduce uncertainty without guessing at a diagnosis. Focus on the affected fixture, water type, scope, and any change in symptoms.
- Close the heater’s water supply if a leak continues and you can safely reach the correct valve.
- Keep belongings away from the wet area and avoid electrical equipment when water has spread around it.
- Do not disassemble safety valves or heater components while trying to stop the leak.
If the situation changes while you are checking the area, treat the new symptom as important information and avoid continuing to use plumbing that is actively leaking, overflowing, or returning wastewater.
