When Do You Need a Water Heater Replacement?
Most water heaters last 8–12 years. After that, signs of failure often include:
- No hot water
- Leaking tank or pooling water
- Pilot light won’t stay lit
- Faulty thermostat or heating element
In some cases, our technicians can repair the issue—but if the tank is leaking or too old, a full water heater replacement is usually the safest and most cost-effective solution.
