What to Do When Your Water Heater is Leaking
Finding water around your water heater is alarming—but don't panic. Some leaks are minor and fixable. Others signal it's time for replacement. Here's how to assess the situation and take the right action.
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** — In humid Tyler summers, cold pipes can "sweat"
- **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:
Turn the gas control valve to "Pilot" or "Off" position. This stops heating but keeps the pilot light (or shuts everything down).
For Electric Water Heaters:
Flip the dedicated breaker in your electrical panel to "Off."
Step 3: Shut Off the Water Supply
Locate the cold water supply valve on top of or above the water heater. Turn it clockwise to close. If this valve is stuck or broken, shut off your home's main water valve.
Step 4: Identify the Leak Location
Top Leaks (Usually Fixable):
- Loose inlet/outlet connections — Tighten fittings
- Faulty T&P valve — May need replacement
- Condensation — Not a true leak
Side Leaks:
- Temperature & Pressure (T&P) valve discharge — Could indicate excess pressure
- Internal tank corrosion showing through — Replacement likely needed
Bottom Leaks (Often Serious):
- Drain valve — May just need tightening or replacement
- Internal tank failure — The tank itself is corroding from inside
- Bottom of tank rusted through — Replacement required
Step 5: Assess Repair vs. Replace
Consider Repair If:
- Water heater is less than 8 years old
- Leak is from a valve or fitting (not the tank)
- Single issue, no other problems
Consider Replacement If:
- Unit is 10+ years old
- Leak is from the tank itself
- You've had multiple repairs recently
- Rust in hot water
The 50% Rule
If repair costs exceed 50% of a new water heater installation, replacement makes more financial sense.
Emergency Actions
If the leak is severe:
- Turn off water and power immediately
- Place towels or a wet-vac to contain water
- Move belongings away from the area
- Call for emergency service
Water Heater Life Expectancy
- Tank water heaters: 8-12 years
- Tankless water heaters: 20+ years
- East Texas hard water may shorten lifespan
Annual maintenance (flushing sediment, checking anode rod) extends water heater life significantly.
