If the noises persist, it may be a sign of a more serious problem, such as a faulty heating element, and it’s best to call in a professional.
Leaking or Pooling Water Around the Heater
If you notice water pooling around the base of your water heater or leaking from the unit itself, it’s likely due to a faulty temperature and pressure relief valve or a leak in the tank. Try replacing the valve first, and if that doesn’t solve the problem, it may be time to replace the entire unit.
Smelly or Discolored Water
If your hot water has a foul odor or appears discolored, it’s likely due to a buildup of bacteria in the tank. To fix this, try flushing the tank and adding a small amount of hydrogen peroxide to the water. If the problem persists, it may be time to replace the unit.
By following these simple solutions, you can fix common water heater problems and enjoy consistent, reliable hot water once again.
