What to Do When Your Water Heater is Leaking
Water around a water heater can come from the tank, a connection, a valve or discharge pipe, the drain pan, condensation, or nearby equipment. Do not select a repair or replacement from the puddle alone; first identify visible conditions without touching unsafe controls or hot water.
Step 1: Confirm the Source
Before assuming the worst, verify the water is actually coming from your water heater:
- Check nearby pipes — Supply lines, drain lines, and connections can leak
- Look for condensation — Cold piping and equipment can collect condensation under some conditions
- Check the drain pan — If there's a pan, water might be from a condensate line nearby
- Inspect the HVAC — Water heaters near AC systems may catch overflow
Step 2: Turn Off the Power
For Gas Water Heaters:
If gas odor, combustion, or venting is suspected, leave the area and contact the gas utility or 911 from a safe location. Otherwise, use only the manufacturer emergency-shutdown instructions for the exact model; do not operate an unfamiliar control.
For Electric Water Heaters:
Keep away from standing water and exposed electrical equipment. Use the identified disconnect or breaker only when it is safe and you know it supplies the unit; otherwise contact a qualified provider.
Step 3: Shut Off the Water Supply
Use the identified cold-water shutoff only if it is accessible and safe to operate. Do not force a stuck or damaged valve. If water is spreading and the fixture shutoff cannot be used safely, use the building shutoff only if you know its location and operation.
Step 4: Identify the Leak Location
Water Seen Near the Top:
- Inlet, outlet, valve, or nearby piping — record the exact wet point without tightening a hot or pressurized connection
- Relief-valve or discharge piping — do not cap or plug it; record when discharge occurs
- Condensation or water from nearby equipment — compare the source and timing
Water Seen at a Side Connection or Jacket:
- Relief-valve discharge can involve temperature, pressure, the valve, or system conditions and needs diagnosis
- Corrosion, seam leakage, or water tracking from above should be distinguished before a decision
Water Seen at the Bottom:
- A drain valve, pan, piping connection, or water tracking down the jacket may be involved
- A leaking tank or heat exchanger changes repair-versus-replacement options
- Record corrosion, the wettest point, and whether water continues with the unit isolated
Step 5: Assess Repair vs. Replace
Repair may be considered when:
- The diagnosed problem is isolated to a compatible replaceable component
- The tank or heat exchanger is not leaking
- The equipment condition supports continued service
Replacement may be considered when:
- The tank or heat exchanger is leaking
- Required parts are unavailable or incompatible
- Corrosion, capacity, utility, or code requirements limit a repair
Emergency Actions
If the leak is severe:
- Turn off water and the appropriate fuel or power source only when it is safe
- Place towels or a wet-vac to contain water
- Move belongings away from the area
- Call for emergency service
Equipment Age and Documentation
Record the model and serial number, installation date if known, fuel or power source, prior repairs, and manufacturer maintenance instructions. Age is one factor, but the diagnosed condition and compatible parts determine whether repair is practical.
