How to Diagnose the Leak
- Turn Off the Power and Water Supply
- For electric water heaters, turn off the circuit breaker.
- For gas water heaters, turn off the gas valve.
- Shut off the cold water supply to the unit.
- Identify the Source of the Leak
- Drain Valve: Check if water is dripping from the drain valve. Tighten it or replace if faulty.
- TPR Valve: If water is leaking from the TPR valve, it may be faulty. Replace it immediately.
- Tank: If the leak is coming from the tank itself, the unit may need replacement.
- Inspect the Heating Element Gasket
- For electric water heaters, check the gasket around the heating element. If it’s loose or damaged, tighten or replace it.

When to Replace Your Water Heater
If the leak is coming from the tank itself, it’s usually a sign of corrosion or structural damage. In this case, the water heater will need to be replaced. Other signs that it’s time for a replacement include:
- The unit is over 10 years old.
- Rusty water is coming from the taps.
- The water heater is making unusual noises (e.g., popping, rumbling).
Preventing Leaks in the Future
- Flush the tank annually to remove sediment and prevent corrosion.
- Inspect the anode rod every 2–3 years and replace if corroded.
- Check for leaks regularly around the base and connections.
- Install a water softener if you have hard water to reduce mineral buildup.
